3ff468ef98 net: mscc: ocelot: remove struct ocelot_mm_state :: lock
Unfortunately, the workarounds for the hardware bugs make it pointless
to keep fine-grained locking for the MAC Merge state of each port.

Our vsc9959_cut_through_fwd() implementation requires
ocelot->fwd_domain_lock to be held, in order to serialize with changes
to the bridging domains and to port speed changes (which affect which
ports can be cut-through). Simultaneously, the traffic classes which can
be cut-through cannot be preemptible at the same time, and this will
depend on the MAC Merge layer state (which changes from threaded
interrupt context).

Since vsc9959_cut_through_fwd() would have to hold the mm->lock of all
ports for a correct and race-free implementation with respect to
ocelot_mm_irq(), in practice it means that any time a port's mm->lock is
held, it would potentially block holders of ocelot->fwd_domain_lock.

In the interest of simple locking rules, make all MAC Merge layer state
changes (and preemptible traffic class changes) be serialized by the
ocelot->fwd_domain_lock.

15f93f46f3 net: mscc: ocelot: export a single ocelot_mm_irq()
When the switch emits an IRQ, we don't know what caused it, and we
iterate through all ports to check the MAC Merge status.

Move that iteration inside the ocelot lib; we will change the locking in
a future change and it would be good to encapsulate that lock completely
within the ocelot lib.

9ecd05794b net: mscc: ocelot: strengthen type of "u32 reg" in I/O accessors
The "u32 reg" argument that is passed to these functions is not a plain
address, but rather a driver-specific encoding of another enum
ocelot_target target in the upper bits, and an index into the
u32 ocelot->map[target][] array in the lower bits. That encoded value
takes the type "enum ocelot_reg" and is what is passed to these I/O
functions, so let's actually use that to prevent type confusion.

d1aae06630 clk: starfive: Avoid casting iomem pointers
Let's use a wrapper struct for the auxiliary_device made in
jh7110_reset_controller_register() so that we can stop casting iomem
pointers. The casts trip up tools like sparse, and make for some awkward
casts that are largely unnecessary. While we're here, change the
allocation from devm and actually free the auxiliary_device memory in
the release function. This avoids any use after free problems where the
parent device driver is unbound from the device but the
auxiliuary_device is still in use accessing devm freed memory.

2afbf43a4a soc: qcom: Make the Qualcomm UFS/SDCC ICE a dedicated driver
This takes the already existing duplicated support in both ufs-qcom
and sdhci-msm drivers and makes it a dedicated driver that can be used
by both mentioned drivers.

The reason for this is because, staring with SM8550, the ICE IP block
is shared between UFS and SDCC, which means we need to probe a dedicated
device and share it between those two consumers.

So let's add the ICE dedicated driver as a soc driver.

Platforms that already have ICE supported, will use it as a library
as the of_qcom_ice_get will return an ICE instance created for the
consumer device. This allows the backwards compatibility with old-style
devicetree approach.

Also, add support to HW version 4.x since it works out-of-the-box with
the current driver. The 4.x HW version is found on SM8550 platform.

6505b68056 net: mscc: ocelot: add MAC Merge layer support for VSC9959
Felix (VSC9959) has a DEV_GMII:MM_CONFIG block composed of 2 registers
(ENABLE_CONFIG and VERIF_CONFIG). Because the MAC Merge statistics and
pMAC statistics are already in the Ocelot switch lib even if just Felix
supports them, I'm adding support for the whole MAC Merge layer in the
common Ocelot library too.

There is an interrupt (shared with the PTP interrupt) which signals
changes to the MM verification state. This is done because the
preemptible traffic classes should be committed to hardware only once
the verification procedure has declared the link partner of being
capable of receiving preemptible frames.

We implement ethtool getters and setters for the MAC Merge layer state.
The "TX enabled" and "verify status" are taken from the IRQ handler,
using a mutex to ensure serialized access.

ab3f97a961 net: mscc: ocelot: export ethtool MAC Merge stats for Felix VSC9959
The Felix VSC9959 switch supports frame preemption and has a MAC Merge
layer. In addition to the structured stats that exist for the eMAC,
export the counters associated with its pMAC (pause, RMON, MAC, PHY,
control) plus the high-level MAC Merge layer stats. The unstructured
ethtool counters, as well as the rtnl_link_stats64 were left to report
only the eMAC counters.

Because statistics processing is quite self-contained in ocelot_stats.c
now, I've opted for introducing an ocelot->mm_supported bool, based on
which the common switch lib does everything, rather than pushing the
TSN-specific code in felix_vsc9959.c, as happens for other TSN stuff.

Merge tag 'drm-next-2022-12-13' of git://anongit.freedesktop.org/drm/drm

Pull drm updates from Dave Airlie:
 "The biggest highlight is that the accel subsystem framework is merged.
  Hopefully for 6.3 we will be able to line up a driver to use it.

  In drivers land, i915 enables DG2 support by default now, and nouveau
  has a big stability refactoring and initial ampere support, AMD
  includes new hw IP support and should build on ARM again. There is
  also an ofdrm driver to take over offb on platforms it's used.

  Stuff outside my tree, the dma-buf patches hit a few places, the vc4
  firmware changes also do, and i915 has some interactions with MEI for
  discrete GPUs. I think all of those should have been acked/reviewed by

8e17b16a2c SoC driver updates for 6.2
There are few major updates in the SoC specific drivers, mainly the usual
 reworks and support for variants of the existing SoC.  While this remains
 Arm centric for the most part, the branch now also contains updates to
 risc-v and loongarch specific code in drivers/soc/.
 
 Notable changes include:
 
  - Support for the newly added Qualcomm Snapdragon variants
    (MSM8956, MSM8976, SM6115, SM4250, SM8150, SA8155 and SM8550) in the
    soc ID, rpmh, rpm, spm and powerdomain drivers.
 
  - Documentation for the somewhat controversial qcom,board-id
    properties that are required for booting a number of machines
 
  - A new SoC identification driver for the loongson-2 (loongarch)
    platform
 
  - memory controller updates for stm32, tegra, and renesas.
 
  - a new DT binding to better describe LPDDR2/3/4/5 chips in
    the memory controller subsystem
 
  - Updates for Tegra specific drivers across multiple subsystems,
    improving support for newer SoCs and better identification
 
  - Minor fixes for Broadcom, Freescale, Apple, Renesas, Sifive,
    TI, Mediatek and Marvell SoC drivers

Merge tag 'soc-drivers-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC driver updates from Arnd Bergmann:
 "There are few major updates in the SoC specific drivers, mainly the
  usual reworks and support for variants of the existing SoC. While this
  remains Arm centric for the most part, the branch now also contains
  updates to risc-v and loongarch specific code in drivers/soc/.

  Notable changes include:

   - Support for the newly added Qualcomm Snapdragon variants (MSM8956,
     MSM8976, SM6115, SM4250, SM8150, SA8155 and SM8550) in the soc ID,
     rpmh, rpm, spm and powerdomain drivers.

   - Documentation for the somewhat controversial qcom,board-id
     properties that are required for booting a number of machines

   - A new SoC identification driver for the loongson-2 (loongarch)
     platform

   - memory controller updates for stm32, tegra, and renesas.

   - a new DT binding to better describe LPDDR2/3/4/5 chips in the
     memory controller subsystem

   - Updates for Tegra specific drivers across multiple subsystems,
     improving support for newer SoCs and better identification

   - Minor fixes for Broadcom, Freescale, Apple, Renesas, Sifive, TI,
     Mediatek and Marvell SoC drivers"

soc: fsl: qe: request pins non-exclusively
Commit 84582f9ed0 ("soc: fsl: qe: Avoid using gpio_to_desc()") changed
qe_pin_request() to request and hold GPIO corresponding to a given pin.
Unfortunately this does not work, as fhci-hcd requests these GPIOs
first, befor calling qe_pin_request() (see
drivers/usb/host/fhci-hcd.c::of_fhci_probe()).
To fix it change qe_pin_request() to request GPIOs non-exclusively, and
free them once the code determines GPIO controller and offset for each
GPIO/pin.

Also reaching deep into gpiolib implementation is not the best idea. We
should either export gpio_chip_hwgpio() or keep converting to the global
gpio numbers space until we fix the driver to implement proper pin
control.

On Tegra234 NVDEC firmware is loaded from a secure carveout, where it
has been loaded by a bootloader. When booting NVDEC, we need to tell it
the address of this firmware, which we can determine by checking the
starting address of the carveout. As such, add an MC API to query the
bounds of carveouts, and add related information on Tegra234.

Merge tag 'qcom-drivers-for-6.2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers
Qualcomm driver updates for 6.2

The qcom,msm-id and qcom,board-id DeviceTree properties are documented,
to allow them to be used in configurations or devices requiring these
and the socinfo driver is updated to reuse the introduced identifiers.

The rpmh-rsc driver is extended to register for PM runtime notifications
from the CPU clusters, in order to submit sleep and wake votes the last
core in a cluster is being powered down.

A mechanism for keeping rpmhpd resources voted until sync_state is
introduced, this ensures that power-domains required during boot are
kept enabled. The rpmhpd power-domains for SDM670 are also added.

Support for the new QDU1000/QRU1000 platform is introduced in the rpmhpd
and socinfo drivers.

The APR driver gains missing error handling. QMI message descriptors in
the PDR driver are made const.

Support for the RPM found in SM6375 is added. The SPM driver gains
support for MSM8939 and MSM8976 platforms.

The stats and command-db drvers are marked as not having PM support.

Merge tag 'tegra-for-6.2-firmware-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into soc/drivers

firmware: tegra: Changes for v6.2-rc1

This adds new BPMP ABI so that newer features can be enabled.
Furthermore, the BPMP driver is updated to use iosys-map helpers to
allow working with shared memory regions that are located in system
memory.

Apart from that, several minor cleanups are included.

Since commit 4d1d157fb6 ("net: mscc: ocelot: share the common stat
definitions between all drivers") there is no longer a need to share the
stats structures to the world. Relocate these definitions to inside
ocelot_stats.c instead of a global include header.

bdc753c7fc Here's the main clk pull request for this merge window. We have some
late breaking reports that a patch series to rework clk rate range
 support broke boot on some devices, so I've left that branch out of this
 PR. Hopefully we can get to that next week, or punt on it and let it
 bake another cycle. That means we don't really have any changes to the
 core framework this time around besides a few typo fixes. Instead this
 is all clk driver updates and fixes.
 
 The usual suspects are here (again), with Qualcomm dominating the
 diffstat. We look to have gained support for quite a few new Qualcomm
 SoCs and Dmitry worked on updating many of the existing Qualcomm drivers
 to use clk_parent_data. After that we have MediaTek drivers getting some
 much needed updates, in particular to support GPU DVFS. There are also
 quite a few Samsung clk driver patches, but that's mostly because there
 was a maintainer change and so last release we missed some of those
 patches.
 
 Overall things look normal, but I'm slowly reviewing core framework code
 nowadays and that shows given the rate range patches had to be yanked
 last minute. Let's hope this situation changes soon.
 
 New Drivers:
  - Support for Renesas VersaClock7 clock generator family
  - Add Spreadtrum UMS512 SoC clk support
  - New clock drivers for MediaTek Helio X10 MT6795
  - Display clks for Qualcomm SM6115, SM8450
  - GPU clks for Qualcomm SC8280XP
  - Qualcomm MSM8909 and SM6375 global and SMD RPM clk drivers
 
 Deleted Drivers:
  - Remove DaVinci DM644x and DM646x clk driver support
 
 Updates:
  - Convert Baikal-T1 CCU driver to platform driver
  - Split reset support out of primary Baikal-T1 CCU driver
  - Add some missing clks required for RPiVid Video Decoder on RaspberryPi
  - Mark PLLC critical on bcm2835
  - More devm helpers for fixed rate registration
  - Various PXA168 clk driver fixes
  - Add resets for MediaTek MT8195 PCIe and USB
  - Miscellaneous of_node_put() fixes
  - Nuke dt-bindings/clk path (again) by moving headers to dt-bindings/clock
  - Convert gpio-clk-gate binding to YAML
  - Various fixes to AMD/Xilinx Zynqmp clk driver
  - Graduate AMD/Xilinx "clocking wizard" driver from staging
  - Add missing DPI1_HDMI clock in MT8195 VDOSYS1
  - Clock driver changes to support GPU DVFS on MT8183, MT8192, MT8195
    - Fix GPU clock topology on MT8195
    - Propogate rate changes from GPU clock gate up the tree
    - Clock mux notifiers for GPU-related PLLs
  - Conversion of more "simple" drivers to mtk_clk_simple_probe()
  - Hook up mtk_clk_simple_remove() for "simple" MT8192 clock drivers
  - Fixes to previous |struct clk| to |struct clk_hw| conversion on MediaTek
  - Shrink MT8192 clock driver by deduplicating clock parent lists
  - Change order between 'sim_enet_root_clk' and 'enet_qos_root_clk'
    clocks for i.MX8MP
  - Drop unnecessary newline in i.MX8MM dt-bindings
  - Add more MU1 and SAI clocks dt-bindings Ids
  - Introduce slice busy bit check for i.MX93 composite clock
  - Introduce white list bit check for i.MX93 composite clock
  - Add new i.MX93 clock gate
  - Add MU1 and MU2 clocks to i.MX93 clock provider
  - Add SAI IPG clocks to i.MX93 clock provider
  - add generic clocks for U(S)ART available on SAMA5D2 SoCs
  - reset controller support for Polarfire clocks
  - .round_rate and .set rate support for clk-mpfs
  - code cleanup for clk-mpfs
  - PLL support for PolarFire SoC's Clock Conditioning Circuitry
  - Add watchdog, I2C, pin control/GPIO, and Ethernet clocks on R-Car V4H
  - Add SDHI, Timer (CMT/TMU), and SPI (MSIOF) clocks on R-Car S4-8
  - Add I2C clocks and resets on RZ/V2M
  - Document clock support for the RZ/Five SoC
  - mux-variant clock using the table variant to select parents
  - clock controller for the rv1126 soc
  - conversion of rk3128 to yaml and relicensing of the yaml bindings
    to gpl2+MIT (following dt-binding guildelines)
  - Exynos7885: add FSYS, TREX and MFC clock controllers
  - Exynos850: add IS and AUD (audio) clock controllers with bindings
  - ExynosAutov9: add FSYS clock controllers with bindings
  - ExynosAutov9: correct clock IDs in bindings of Peric 0 and 1 clock

Pull clk updates from Stephen Boyd:
 "We have some late breaking reports that a patch series to rework clk
  rate range support broke boot on some devices, so I've left that
  branch out of this. Hopefully we can get to that next week, or punt on
  it and let it bake another cycle. That means we don't really have any
  changes to the core framework this time around besides a few typo
  fixes. Instead this is all clk driver updates and fixes.

  The usual suspects are here (again), with Qualcomm dominating the
  diffstat. We look to have gained support for quite a few new Qualcomm
  SoCs and Dmitry worked on updating many of the existing Qualcomm
  drivers to use clk_parent_data. After that we have MediaTek drivers
  getting some much needed updates, in particular to support GPU DVFS.
  There are also quite a few Samsung clk driver patches, but that's
  mostly because there was a maintainer change and so last release we
  missed some of those patches.

  Overall things look normal, but I'm slowly reviewing core framework
  code nowadays and that shows given the rate range patches had to be
  yanked last minute. Let's hope this situation changes soon.

  New Drivers:
   - Support for Renesas VersaClock7 clock generator family
   - Add Spreadtrum UMS512 SoC clk support
   - New clock drivers for MediaTek Helio X10 MT6795
   - Display clks for Qualcomm SM6115, SM8450
   - GPU clks for Qualcomm SC8280XP
   - Qualcomm MSM8909 and SM6375 global and SMD RPM clk drivers

  Deleted Drivers:
   - Remove DaVinci DM644x and DM646x clk driver support

  Updates:
   - Convert Baikal-T1 CCU driver to platform driver
   - Split reset support out of primary Baikal-T1 CCU driver
   - Add some missing clks required for RPiVid Video Decoder on

   - Mark PLLC critical on bcm2835
   - More devm helpers for fixed rate registration
   - Various PXA168 clk driver fixes

ff6862c23d ARM: driver updates for 6.1
The drivers branch for 6.1 is a bit larger than for most releases.  Most
 of the changes come from SoC maintainers for the drivers/soc subsystem:
 
  - A new driver for error handling on the NVIDIA Tegra
    'control backbone' bus.
 
  - A new driver for Qualcomm LLCC/DDR bandwidth measurement
 
  - New Rockchip rv1126 and rk3588 power domain drivers
 
  - DT binding updates for memory controllers, older Rockchip
    SoCs, various Mediatek devices, Qualcomm SCM firmware
 
  - Minor updates to Hisilicon LPC bus, the Allwinner SRAM
    driver, the Apple rtkit firmware driver, Tegra firmware
 
  - Minor updates for SoC drivers (Samsung, Mediatek, Renesas,
    Tegra, Qualcomm, Broadcom, NXP, ...)
 
 There are also some separate subsystem with downstream maintainers that
 merge updates this way:
 
  - Various updates and new drivers in the memory controller
    subsystem for Mediatek and Broadcom SoCs
 
  - Small set of changes in preparation to add support for FF-A
    v1.1 specification later, in the Arm FF-A firmware subsystem
 
  - debugfs support in the PSCI firmware subsystem

eca70102cf net: dsa: felix: add support for changing DSA master
Changing the DSA master means different things depending on the tagging
protocol in use.

For NPI mode ("ocelot" and "seville"), there is a single port which can
be configured as NPI, but DSA only permits changing the CPU port
affinity of user ports one by one. So changing a user port to a
different NPI port globally changes what the NPI port is, and breaks the
user ports still using the old one.

To address this while still permitting the change of the NPI port,
require that the user ports which are still affine to the old NPI port
are down, and cannot be brought up until they are all affine to the same
NPI port.

The tag_8021q mode ("ocelot-8021q") is more flexible, in that each user
port can be freely assigned to one CPU port or to the other. This works
by filtering host addresses towards both tag_8021q CPU ports, and then
restricting the forwarding from a certain user port only to one of the
two tag_8021q CPU ports.

Additionally, the 2 tag_8021q CPU ports can be placed in a LAG. This
works by enabling forwarding via PGID_SRC from a certain user port
towards the logical port ID containing both tag_8021q CPU ports, but
then restricting forwarding per packet, via the LAG hash codes in
PGID_AGGR, to either one or the other.

When we change the DSA master to a LAG device, DSA guarantees us that
the LAG has at least one lower interface as a physical DSA master.
But DSA masters can come and go as lowers of that LAG, and
ds->ops->port_change_master() will not get called, because the DSA
master is still the same (the LAG). So we need to hook into the
ds->ops->port_lag_{join,leave} calls on the CPU ports and update the
logical port ID of the LAG that user ports are assigned to.

Drivers could refuse to offload a LAG configuration for a variety of
reasons, mainly having to do with its TX type. Additionally, since DSA
masters may now also be LAG interfaces, and this will translate into a
call to port_lag_join on the CPU ports, there may be extra restrictions
there. Propagate the netlink extack to this DSA method in order for
drivers to give a meaningful error message back to the user.

b713442214 soc/tegra: cbb: Add CBB 1.0 driver for Tegra194
Adding driver to handle errors from Control Backbone (CBB) which are
generated due to illegal accesses. CBB 1.0 is used in Tegra194 SoCs.
When an error is reported from a NOC within CBB, the driver prints debug
information about failed transaction like Error Code, Error Description,
Master, Address, AXI ID, Cache, Protection, Security Group etc. It then
causes system crash using BUG_ON() or call WARN() based on whether the
error type is fatal or not.

96765cc475 soc/tegra: Set ERD bit to mask inband errors
Add a function to set the ERD (Error Response Disable) bit in the
MISCREG_CCROC_ERR_CONFIG register from the Control Backbone (CBB) error
handler driver.

ERD bit allows masking of SError due to inband errors which are caused
by illegal register accesses through CBB. When the bit is set, interrupt
is used for reporting errors and magic code '0xdead2003' is returned.
This change is only required for Tegra194 SoC as the config is moved to
CBB register space for future SoC's. Also, remove unmapping the
apbmisc_base as it's required to get the base address for accessing the
misc register.

4d1d157fb6 net: mscc: ocelot: share the common stat definitions between all drivers
All switch families supported by the ocelot lib (ocelot, felix, seville)
export the same registers so far. But for example felix also has TSN
counters, while the others don't.

To reduce the bloat even further, create an OCELOT_COMMON_STATS() macro
which just lists all stats that are common between switches. The array
elements are still replicated among all of vsc9959_stats_layout,
vsc9953_stats_layout and ocelot_stats_layout.

b69cf1c675 net: mscc: ocelot: minimize definitions for stats
The current definition of struct ocelot_stat_layout is long-winded (4
lines per entry, and we have hundreds of entries), so we could make an
effort to use the C preprocessor and reduce the line count.

Create an implicit correspondence between enum ocelot_reg, which tells
us the register address (SYS_COUNT_RX_OCTETS etc) and enum ocelot_stat
which allows us to index the ocelot->stats array (OCELOT_STAT_RX_OCTETS
etc), and don't require us to specify both when we define what stats
each switch family has.

Create an OCELOT_STAT() macro that pairs only an enum ocelot_stat to an
enum ocelot_reg, and an OCELOT_STAT_ETHTOOL() macro which also contains
a name exported to the unstructured ethtool -S stringset API. For now,
we define all counters as having the OCELOT_STAT_ETHTOOL() kind, but we
will add more counters in the future which are not exported to the
unstructured ethtool -S.

e32036e1ae net: mscc: ocelot: add support for all sorts of standardized counters present in DSA
DSA is integrated with the new standardized ethtool -S --groups option,
but the felix driver only exports unstructured statistics.

Reuse the array of 64-bit statistics collected by ocelot_check_stats_work(),
but just export select values from it.

Since ocelot_check_stats_work() runs periodically to avoid 32-bit
overflow, and the ethtool calling context is sleepable, we update the
64-bit stats one more time, to provide up-to-date values. The locking
scheme with a mutex followed by a spinlock is a bit hard to digest, so
we create and use a ocelot_port_stats_run() helper with a callback that
populates the ethool stats group the caller is interested in.

The exported stats are:
ethtool -S swp0 --groups eth-phy
ethtool -S swp0 --groups eth-mac
ethtool -S swp0 --groups eth-ctrl
ethtool -S swp0 --groups rmon
ethtool --include-statistics --show-pause swp0

25027c8409 net: dsa: felix: check the 32-bit PSFP stats against overflow
The Felix PSFP counters suffer from the same problem as the ocelot
ndo_get_stats64 ones - they are 32-bit, so they can easily overflow and
this can easily go undetected.

Add a custom hook in ocelot_check_stats_work() through which driver
specific actions can be taken, and update the stats for the existing
PSFP filters from that hook.

Previously, vsc9959_psfp_filter_add() and vsc9959_psfp_filter_del() were
serialized with respect to each other via rtnl_lock(). However, with the
new entry point into &psfp->sfi_list coming from the periodic worker, we
now need an explicit mutex to serialize access to these lists.

We used to keep a struct felix_stream_filter_counters on stack, through
which vsc9959_psfp_stats_get() - a FLOW_CLS_STATS callback - would
retrieve data from vsc9959_psfp_counters_get(). We need to become
smarter about that in 3 ways:

- we need to keep a persistent set of counters for each stream instead
  of keeping them on stack

- we need to promote those counters from u32 to u64, and create a
  procedure that properly keeps 64-bit counters. Since we clear the
  hardware counters anyway, and we poll every 2 seconds, a simple
  increment of a u64 counter with a u32 value will perfectly do the job.

- FLOW_CLS_STATS also expect incremental counters, so we also need to
  zeroize our u64 counters every time sch_flower calls us

7a94b83a7d ARM: at91: pm: fix DDR recalibration when resuming from backup and self-refresh
On SAMA7G5, when resuming from backup and self-refresh, the bootloader
performs DDR PHY recalibration by restoring the value of ZQ0SR0 (stored
in RAM by Linux before going to backup and self-refresh). It has been
discovered that the current procedure doesn't work for all possible values
that might go to ZQ0SR0 due to hardware bug. The workaround to this is to
avoid storing some values in ZQ0SR0. Thus Linux will read the ZQ0SR0
register and cache its value in RAM after processing it (using
modified_gray_code array). The bootloader will restore the processed value.

36a0bf4435 net: mscc: ocelot: set up tag_8021q CPU ports independent of user port affinity
This is a partial revert of commit c295f9831f ("net: mscc: ocelot:
switch from {,un}set to {,un}assign for tag_8021q CPU ports"), because
as it turns out, this isn't how tag_8021q CPU ports under a LAG are
supposed to work.

Under that scenario, all user ports are "assigned" to the single
tag_8021q CPU port represented by the logical port corresponding to the
bonding interface. So one CPU port in a LAG would have is_dsa_8021q_cpu
set to true (the one whose physical port ID is equal to the logical port
ID), and the other one to false.

In turn, this makes 2 undesirable things happen:

(1) PGID_CPU contains only the first physical CPU port, rather than both
(2) only the first CPU port will be added to the private VLANs used by
    ocelot for VLAN-unaware bridging

To make the driver behave in the same way for both bonded CPU ports, we
need to bring back the old concept of setting up a port as a tag_8021q
CPU port, and this is what deals with VLAN membership and PGID_CPU
updating. But we also need the CPU port "assignment" (the user to CPU
port affinity), and this is what updates the PGID_SRC forwarding rules.

All DSA CPU ports are statically configured for tag_8021q mode when the
tagging protocol is changed to ocelot-8021q. User ports are "assigned"
to one CPU port or the other dynamically (this will be handled by a

d4c3676507 net: mscc: ocelot: keep ocelot_stat_layout by reg address, not offset
With so many counter addresses recently discovered as being wrong, it is
desirable to at least have a central database of information, rather
than two: one through the SYS_COUNT_* registers (used for
ndo_get_stats64), and the other through the offset field of struct
ocelot_stat_layout elements (used for ethtool -S).

The strategy will be to keep the SYS_COUNT_* definitions as the single
source of truth, but for that we need to expand our current definitions
to cover all registers. Then we need to convert the ocelot region
creation logic, and stats worker, to the read semantics imposed by going
through SYS_COUNT_* absolute register addresses, rather than offsets
of 32-bit words relative to SYS_COUNT_RX_OCTETS (which should have been
SYS_CNT, by the way).

9190460084 net: mscc: ocelot: make struct ocelot_stat_layout array indexable
The ocelot counters are 32-bit and require periodic reading, every 2
seconds, by ocelot_port_update_stats(), so that wraparounds are
detected.

Currently, the counters reported by ocelot_get_stats64() come from the
32-bit hardware counters directly, rather than from the 64-bit
accumulated ocelot->stats, and this is a problem for their integrity.

The strategy is to make ocelot_get_stats64() able to cherry-pick
individual stats from ocelot->stats the way in which it currently reads
them out from SYS_COUNT_* registers. But currently it can't, because
ocelot->stats is an opaque u64 array that's used only to feed data into
ethtool -S.

To solve that problem, we need to make ocelot->stats indexable, and
associate each element with an element of struct ocelot_stat_layout used
by ethtool -S.

This makes ocelot_stat_layout a fat (and possibly sparse) array, so we
need to change the way in which we access it. We no longer need
OCELOT_STAT_END as a sentinel, because we know the array's size
(OCELOT_NUM_STATS). We just need to skip the array elements that were
left unpopulated for the switch revision (ocelot, felix, seville).

22d842e3ef net: mscc: ocelot: turn stats_lock into a spinlock
ocelot_get_stats64() currently runs unlocked and therefore may collide
with ocelot_port_update_stats() which indirectly accesses the same
counters. However, ocelot_get_stats64() runs in atomic context, and we
cannot simply take the sleepable ocelot->stats_lock mutex. We need to
convert it to an atomic spinlock first. Do that as a preparatory change.

5152de7b79 net: mscc: ocelot: fix incorrect ndo_get_stats64 packet counters
Reading stats using the SYS_COUNT_* register definitions is only used by
ocelot_get_stats64() from the ocelot switchdev driver, however,
currently the bucket definitions are incorrect.

Separately, on both RX and TX, we have the following problems:
- a 256-1023 bucket which actually tracks the 256-511 packets
- the 1024-1526 bucket actually tracks the 512-1023 packets
- the 1527-max bucket actually tracks the 1024-1526 packets

=> nobody tracks the packets from the real 1527-max bucket

Additionally, the RX_PAUSE, RX_CONTROL, RX_LONGS and RX_CLASSIFIED_DROPS
all track the wrong thing. However this doesn't seem to have any
consequence, since ocelot_get_stats64() doesn't use these.

Even though this problem only manifests itself for the switchdev driver,
we cannot split the fix for ocelot and for DSA, since it requires fixing
the bucket definitions from enum ocelot_reg, which makes us necessarily
adapt the structures from felix and seville as well.

8670dc33f4 net: dsa: felix: update base time of time-aware shaper when adjusting PTP time
When adjusting the PTP clock, the base time of the TAS configuration
will become unreliable. We need reset the TAS configuration by using a
new base time.

For example, if the driver gets a base time 0 of Qbv configuration from
user, and current time is 20000. The driver will set the TAS base time
to be 20000. After the PTP clock adjustment, the current time becomes
10000. If the TAS base time is still 20000, it will be a future time,
and TAS entry list will stop running. Another example, if the current
time becomes to be 10000000 after PTP clock adjust, a large time offset
can cause the hardware to hang.

This patch introduces a tas_clock_adjust() function to reset the TAS
module by using a new base time after the PTP clock adjustment. This can
avoid issues above.

Due to PTP clock adjustment can occur at any time, it may conflict with
the TAS configuration. We introduce a new TAS lock to serialize the
access to the TAS registers.

Pull networking updates from Jakub Kicinski:
 "Core
  ----

   - Support TCPv6 segmentation offload with super-segments larger than
     64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP).

   - Generalize skb freeing deferral to per-cpu lists, instead of
     per-socket lists.

   - Add a netdev statistic for packets dropped due to L2 address
     mismatch (rx_otherhost_dropped).

   - Continue work annotating skb drop reasons.

   - Accept alternative netdev names (ALT_IFNAME) in more netlink
     requests.

   - Add VLAN support for AF_PACKET SOCK_RAW GSO.

   - Allow receiving skb mark from the socket as a cmsg.

   - Enable memcg accounting for veth queues, sysctl tables and IPv6.

  BPF
  ---

   - Add libbpf support for User Statically-Defined Tracing (USDTs).

   - Speed up symbol resolution for kprobes multi-link attachments.

   - Support storing typed pointers to referenced and unreferenced
     objects in BPF maps.

   - Add support for BPF link iterator.

   - Introduce access to remote CPU map elements in BPF per-cpu map.

   - Allow middle-of-the-road settings for the
     kernel.unprivileged_bpf_disabled sysctl.

   - Implement basic types of dynamic pointers e.g. to allow for
     dynamically sized ringbuf reservations without extra memory copies.

  Protocols
  ---------

   - Retire port only listening_hash table, add a second bind table
     hashed by port and address. Avoid linear list walk when binding to
     very popular ports (e.g. 443).

   - Add bridge FDB bulk flush filtering support allowing user space to
     remove all FDB entries matching a condition.

   - Introduce accept_unsolicited_na sysctl for IPv6 to implement
     router-side changes for RFC9131.

   - Support for MPTCP path manager in user space.

   - Add MPTCP support for fallback to regular TCP for connections that
     have never connected additional subflows or transmitted
     out-of-sequence data (partial support for RFC8684 fallback).

   - Avoid races in MPTCP-level window tracking, stabilize and improve
     throughput.

   - Support lockless operation of GRE tunnels with seq numbers enabled.

   - WiFi support for host based BSS color collision detection.

   - Add support for SO_TXTIME/SCM_TXTIME on CAN sockets.

   - Support transmission w/o flow control in CAN ISOTP (ISO 15765-2).

   - Support zero-copy Tx with TLS 1.2 crypto offload (sendfile).

   - Allow matching on the number of VLAN tags via tc-flower.

   - Add tracepoint for tcp_set_ca_state().

  Driver API
  ----------

   - Add support for listing line cards in switches (devlink).

   - Add helpers for reporting page pool statistics with ethtool -S.

   - Add support for reading clock cycles when using PTP virtual clocks,
     instead of having the driver convert to time before reporting. This
     makes it possible to report time from different vclocks.

   - Support configuring low-latency Tx descriptor push via ethtool.

   - Separate Clause 22 and Clause 45 MDIO accesses more explicitly.

007c3ff11f crypto: caam - add in-kernel interface for blob generator
The NXP Cryptographic Acceleration and Assurance Module (CAAM)
can be used to protect user-defined data across system reboot:

  - When the system is fused and boots into secure state, the master
    key is a unique never-disclosed device-specific key
  - random key is encrypted by key derived from master key
  - data is encrypted using the random key
  - encrypted data and its encrypted random key are stored alongside
  - This blob can now be safely stored in non-volatile memory

On next power-on:
  - blob is loaded into CAAM
  - CAAM writes decrypted data either into memory or key register

Add functions to realize encrypting and decrypting into memory alongside
the CAAM driver.

They will be used in a later commit as a source for the trusted key
seal/unseal mechanism.

a4e044dc4c net: dsa: felix: tag_8021q preparation for multiple CPU ports
Update the VCAP filters to support multiple tag_8021q CPU ports.

TX works using a filter for VLAN ID on the ingress of the CPU port, with
a redirect and a VLAN pop action. This can be updated trivially by
amending the ingress port mask of this rule to match on all tag_8021q
CPU ports.

RX works using a filter for ingress port on the egress of the CPU port,
with a VLAN push action. Here we need to replicate these filters for
each tag_8021q CPU port, and let them all have the same action.
This means that the OCELOT_VCAP_ES0_TAG_8021Q_RXVLAN() cookie needs to
encode a unique value for every {user port, CPU port} pair it's given.
Do this by encoding the CPU port in the upper 16 bits of the cookie, and
the user port in the lower 16 bits.

c295f9831f net: mscc: ocelot: switch from {,un}set to {,un}assign for tag_8021q CPU ports
There is a desire for the felix driver to gain support for multiple
tag_8021q CPU ports, but the current model prevents it.

This is because ocelot_apply_bridge_fwd_mask() only takes into
consideration whether a port is a tag_8021q CPU port, but not whose CPU
port it is.

We need a model where we can have a direct affinity between an ocelot
port and a tag_8021q CPU port. This serves as the basis for multiple CPU
ports.

Declare a "dsa_8021q_cpu" backpointer in struct ocelot_port which
encodes that affinity. Repurpose the "ocelot_set_dsa_8021q_cpu" API to
"ocelot_assign_dsa_8021q_cpu" to express the change of paradigm.

Note that this change makes the first practical use of the new
ocelot_port->index field in ocelot_port_unassign_dsa_8021q_cpu(), where
we need to remove the old tag_8021q CPU port from the reserved VLAN range.

a72e23dd67 net: dsa: felix: update bridge fwd mask from ocelot lib when changing tag_8021q CPU
Add more logic to ocelot_port_{,un}set_dsa_8021q_cpu() from the ocelot
switch lib by encapsulating the ocelot_apply_bridge_fwd_mask() call that
felix used to have.

This is necessary because the CPU port change procedure will also need
to do this, and it's good to reduce code duplication by having an entry
point in the ocelot switch lib that does all that is needed.

d44d6c4a3a Update devfreq next for v5.19
Detailed description for this pull request:
 1. Update devfreq core
 - Add cpu based scaling support to passive governor. Some device like
 cache might require the dynamic frequency scaling. But, it has very
 tightly to cpu frequency. So that use passive governor to scale
 the frequency according to current cpu frequency.
 
 To decide the frequency of the device, the governor does one of the following:
 : Derives the optimal devfreq device opp from required-opps property of
   the parent cpu opp_table.
 
 : Scales the device frequency in proportion to the CPU frequency. So, if
   the CPUs are running at their max frequency, the device runs at its
   max frequency. If the CPUs are running at their min frequency, the
   device runs at its min frequency. It is interpolated for frequencies
   in between.
 
 2. Update devfreq driver
 - Update rk3399_dmc.c as following:
 : Convert dt-binding document to YAML and deprecate unused properties.
 
 : Use Hz units for the device-tree properties of rk3399_dmc.
 
 : rk3399_dmc is able to set the idle time before changing the dmc clock.
   Specify idle time parameters by using nano-second unit on dt bidning.
 
 : Add new disable-freq properties to optimize the power-saving feature
   of rk3399_dmc.
 
 : Disable devfreq-event device on remove() to fix unbalanced
   enable-disable count.
 
 : Use devm_pm_opp_of_add_table()
 
 : Block PMU (Power-Management Unit) transitions when scaling frequency
   by ARM Trust Firmware in order to fix the conflict between PMU and DMC
   (Dynamic Memory Controller).

Merge tag 'devfreq-next-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux

Pull devfreq changes for 5.19-rc1 from Chanwoo Choi:

"1. Update devfreq core

 - Add cpu based scaling support to passive governor. Some device like
   cache might require the dynamic frequency scaling. But, it has very
   tightly to cpu frequency. So that use passive governor to scale
   the frequency according to current cpu frequency.

  To decide the frequency of the device, the governor does one of the following:
  : Derives the optimal devfreq device opp from required-opps property of
    the parent cpu opp_table.

  : Scales the device frequency in proportion to the CPU frequency. So, if
    the CPUs are running at their max frequency, the device runs at its
    max frequency. If the CPUs are running at their min frequency, the
    device runs at its min frequency. It is interpolated for frequencies
    in between.

 2. Update devfreq drivers

  - Update rk3399_dmc.c as following:

   : Convert dt-binding document to YAML and deprecate unused properties.

   : Use Hz units for the device-tree properties of rk3399_dmc.

   : rk3399_dmc is able to set the idle time before changing the dmc clock.
     Specify idle time parameters by using nano-second unit on dt bidning.

   : Add new disable-freq properties to optimize the power-saving feature
     of rk3399_dmc.

   : Disable devfreq-event device on remove() to fix unbalanced
     enable-disable count.

   : Use devm_pm_opp_of_add_table()

   : Block PMU (Power-Management Unit) transitions when scaling frequency
     by ARM Trust Firmware in order to fix the conflict between PMU and DMC
     (Dynamic Memory Controller)."

7e708760fc net: mscc: ocelot: move ocelot_port_private :: chip_port to ocelot_port :: index
Currently the ocelot switch lib is unaware of the index of a struct
ocelot_port, since that is kept in the encapsulating structures of outer
drivers (struct dsa_port :: index, struct ocelot_port_private :: chip_port).

With the upcoming increase in complexity associated with assigning DSA
tag_8021q CPU ports to certain user ports, it becomes necessary for the
switch lib to be able to retrieve the index of a certain ocelot_port.

Therefore, introduce a new u8 to ocelot_port (same size as the chip_port
used by the ocelot switchdev driver) and rework the existing code to
populate and use it.

From Tegra186 onwards, the memory controller supports multiple channels.
Add support for mapping the address spaces of these channels and specify
the number of channels supported by Tegra186, Tegra194 and Tegra234.

In case of old bindings, channels won't be present. If channels are not
present then print a warning and continue so that backward compatibility
will be preserved in driver.

During error interrupts from memory controller, appropriate registers
from these channels need to be accessed for logging error info.

defec178df soc: rockchip: power-domain: Manage resource conflicts with firmware
On RK3399 platforms, power domains are managed mostly by the kernel
(drivers/soc/rockchip/pm_domains.c), but there are a few exceptions
where ARM Trusted Firmware has to be involved:

(1) system suspend/resume
(2) DRAM DVFS (a.k.a., "ddrfreq")

Exception (1) does not cause much conflict, since the kernel has
quiesced itself by the time we make the relevant PSCI call.

Exception (2) can cause conflict, because of two actions:

(a) ARM Trusted Firmware needs to read/modify/write the PMU_BUS_IDLE_REQ
    register to idle the memory controller domain; the kernel driver
    also has to touch this register for other domains.
(b) ARM Trusted Firmware needs to manage the clocks associated with
    these domains.

To elaborate on (b): idling a power domain has always required ungating
an array of clocks; see this old explanation from Rockchip:
https://lore.kernel.org/linux-arm-kernel/54503C19.9060607@rock-chips.com/

Historically, ARM Trusted Firmware has avoided this issue by using a
special PMU_CRU_GATEDIS_CON0 register -- this register ungates all the
necessary clocks -- when idling the memory controller. Unfortunately,
we've found that this register is not 100% sufficient; it does not turn
the relevant PLLs on [0].

So it's possible to trigger issues with something like the following:

1. enable a power domain (e.g., RK3399_PD_VDU) -- kernel will
   temporarily enable relevant clocks/PLLs, then turn them back off
   2. a PLL (e.g., PLL_NPLL) is part of the clock tree for
      RK3399_PD_VDU's clocks but otherwise unused; NPLL is disabled
3. perform a ddrfreq transition (rk3399_dmcfreq_target() -> ...
   drivers/clk/rockchip/clk-ddr.c / ROCKCHIP_SIP_DRAM_FREQ)
   4. ARM Trusted Firmware unagates VDU clocks (via PMU_CRU_GATEDIS_CON0)
   5. ARM Trusted firmware idles the memory controller domain
   6. Step 5 waits on the VDU domain/clocks, but NPLL is still off

i.e., we hang the system.

So for (b), we need to at a minimum manage the relevant PLLs on behalf
of firmware. It's easier to simply manage the whole clock tree, in a
similar way we do in rockchip_pd_power().

For (a), we need to provide mutual exclusion betwen rockchip_pd_power()
and firmware. To resolve that, we simply grab the PMU mutex and release
it when ddrfreq is done.

The Chromium OS kernel has been carrying versions of part of this hack
for a while, based on some new custom notifiers [1]. I've rewritten as a
simple function call between the drivers, which is OK because:

 * the PMU driver isn't enabled, and we don't have this problem at all
   (the firmware should have left us in an OK state, and there are no
   runtime conflicts); or
 * the PMU driver is present, and is a single instance.

And the power-domain driver cannot be removed, so there's no lifetime
management to worry about.

For completeness, there's a 'dmc_pmu_mutex' to guard (likely
theoretical?) probe()-time races. It's OK for the memory controller
driver to start running before the PMU, because the PMU will avoid any
critical actions during the block() sequence.

[0] The RK3399 TRM for PMU_CRU_GATEDIS_CON0 only talks about ungating
    clocks. Based on experimentation, we've found that it does not power
    up the necessary PLLs.

[1] CHROMIUM: soc: rockchip: power-domain: Add notifier to dmc driver
    https://chromium-review.googlesource.com/q/I242dbd706d352f74ff706f5cbf42ebb92f9bcc60
    Notably, the Chromium solution only handled conflict (a), not (b).
    In practice, item (b) wasn't a problem in many cases because we
    never managed to fully power off PLLs. Now that the (upstream) video
    decoder driver performs runtime clock management, we often power off
    NPLL.

e1846cff2f net: mscc: ocelot: mark traps with a bool instead of keeping them in a list
Since the blamed commit, VCAP filters can appear on more than one list.
If their action is "trap", they are chained on ocelot->traps via
filter->trap_list. This is in addition to their normal placement on the
VCAP block->rules list head.

Therefore, when we free a VCAP filter, we must remove it from all lists
it is a member of, including ocelot->traps.

There are at least 2 bugs which are direct consequences of this design
decision.

First is the incorrect usage of list_empty(), meant to denote whether
"filter" is chained into ocelot->traps via filter->trap_list.
This does not do the correct thing, because list_empty() checks whether
"head->next == head", but in our case, head->next == head->prev == NULL.
So we dereference NULL pointers and die when we call list_del().

Second is the fact that not all places that should remove the filter
from ocelot->traps do so. One example is ocelot_vcap_block_remove_filter(),
which is where we have the main kfree(filter). By keeping freed filters
in ocelot->traps we end up in a use-after-free in
felix_update_trapping_destinations().

Attempting to fix all the buggy patterns is a whack-a-mole game which
makes the driver unmaintainable. Actually this is what the previous
patch version attempted to do:
https://patchwork.kernel.org/project/netdevbpf/patch/20220503115728.834457-3-vladimir.oltean@nxp.com/

but it introduced another set of bugs, because there are other places in
which create VCAP filters, not just ocelot_vcap_filter_create():

- ocelot_trap_add()
- felix_tag_8021q_vlan_add_rx()
- felix_tag_8021q_vlan_add_tx()

Relying on the convention that all those code paths must call
INIT_LIST_HEAD(&filter->trap_list) is not going to scale.

So let's do what should have been done in the first place and keep a
bool in struct ocelot_vcap_filter which denotes whether we are looking
at a trapping rule or not. Iterating now happens over the main VCAP IS2
block->rules. The advantage is that we no longer risk having stale
references to a freed filter, since it is only present in that list.
