f753067494 Revert "interconnect: qcom: icc-rpmh: Add BCMs to commit list in pre_aggregate"
This reverts commit f84f5b6f72, which is
causing regressions on some platforms, preventing them to boot or do a
clean reboot. This is because the above commit is sending also all the
zero bandwidth requests to turn off any resources that might be enabled
unnecessarily, but currently this may turn off interconnects that are
enabled by default, but with no consumer to keep them on.

Let's revert this for now as some platforms are not ready for such
change yet. In the future we can introduce some _ignore_unused option
that could keep also the unused resources on platforms that have only
partial interconnect support and also add .shutdown callbacks to deal
with disabling the resources in the right order.

8bf5d31c4f interconnect: qcom: osm-l3: Use driver-specific naming
In situations were the developer screws up by e.g. not giving the OSM
nodes unique identifiers the interconnect framework might mix up nodes
between the OSM L3 provider and e.g. the RPMh provider.

The resulting callstack contains "qcom_icc_set", which is not unique to
the OSM L3 provider driver. Once the faulting qcom_icc_set() is
identified it's further confusing that "qcom_icc_node" is different
between the different drivers.

To avoid this confusion, rename the node struct and the setter in the
OSM L3 driver to include "osm_l3" in their names.

f84f5b6f72 interconnect: qcom: icc-rpmh: Add BCMs to commit list in pre_aggregate
We're only adding BCMs to the commit list in aggregate(), but there are
cases where pre_aggregate() is called without subsequently calling
aggregate(). In particular, in icc_sync_state() when a node with initial
BW has zero requests. Since BCMs aren't added to the commit list in
these cases, we don't actually send the zero BW request to HW. So the
resources remain on unnecessarily.

Add BCMs to the commit list in pre_aggregate() instead, which is always
called even when there are no requests.

ce5a595744 interconnect: qcom: icc-rpmh: Ensure floor BW is enforced for all nodes
We currently only enforce BW floors for a subset of nodes in a path.
All BCMs that need updating are queued in the pre_aggregate/aggregate
phase. The first set() commits all queued BCMs and subsequent set()
calls short-circuit without committing anything. Since the floor BW
isn't set in sum_avg/max_peak until set(), then some BCMs are committed
before their associated nodes reflect the floor.

Set the floor as each node is being aggregated. This ensures that all
all relevant floors are set before the BCMs are committed.

Merge tag 'cfi-v5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull CFI on arm64 support from Kees Cook:
 "This builds on last cycle's LTO work, and allows the arm64 kernels to
  be built with Clang's Control Flow Integrity feature. This feature has
  happily lived in Android kernels for almost 3 years[1], so I'm excited
  to have it ready for upstream.

  The wide diffstat is mainly due to the treewide fixing of mismatched
  list_sort prototypes. Other things in core kernel are to address
  various CFI corner cases. The largest code portion is the CFI runtime
  implementation itself (which will be shared by all architectures
  implementing support for CFI). The arm64 pieces are Acked by arm64
  maintainers rather than coming through the arm64 tree since carrying
  this tree over there was going to be awkward.

  CFI support for x86 is still under development, but is pretty close.
  There are a handful of corner cases on x86 that need some improvements
  to Clang and objtool, but otherwise works well.

  Summary:

   - Clean up list_sort prototypes (Sami Tolvanen)

   - Introduce CONFIG_CFI_CLANG for arm64 (Sami Tolvanen)"

4f0f586bf0 treewide: Change list_sort to use const pointers
list_sort() internally casts the comparison function passed to it
to a different type with constant struct list_head pointers, and
uses this pointer to call the functions, which trips indirect call
Control-Flow Integrity (CFI) checking.

Instead of removing the consts, this change defines the
list_cmp_func_t type and changes the comparison function types of
all list_sort() callers to use const pointers, thus avoiding type
mismatches.

9e856a74bd Merge branch 'icc-sdm660' into icc-next
This patch series adds the SDM660 interconnect provider driver in
order to stop some timeouts and achieve some decent performance by
avoiding to be NoC limited.
It's also providing some power consumption improvement, but I have
only measured that as less heat, which is quite important when
working on thermally constrained devices like smartphones.

Please note that this driver's yaml binding is referring to a MMCC
clock, so this series does depend on the SDM660 MMCC driver that I
have sent separately.
The multimedia clock is required only for the Multimedia NoC (mnoc).

This patch series has been tested against the following devices:
 - Sony Xperia XA2 Ultra (SDM630 Nile Discovery)
 - Sony Xperia 10        (SDM630 Ganges Kirin)
 - Sony Xperia 10 Plus   (SDM636 Ganges Mermaid)

f80a1d4143 interconnect: qcom: Add SDM660 interconnect provider driver
Introduce a driver for the Qualcomm interconnect busses found in

The topology consists of several NoCs that are controlled by a
remote processor that collects the aggregated bandwidth for each
master-slave pairs.

On a note, these chips are managing the "bus QoS" in a "hybrid"
fashion: some of the paths in the topology are managed through
(and by, of course) the RPM uC, while some others are "AP Owned",
meaning that the AP shall do direct writes to the appropriate
QoS registers for the specific paths and ports, instead of sending
an indication to the RPM and leaving the job to that one.

Some nodes are incorrectly marked as RPM-controlled (they have RPM
master and slave ids assigned), but are actually controlled by the
application CPU instead. The RPM complains when we send requests for
resources that it can't control. Let's fix this by replacing the IDs,
with the default "-1" in which case no requests are sent.

9805529ec5 ARM: device tree updates for 5.11
Across all platforms, there is a continued move towards DT schema for
 validating the dts files. As a result there are bug fixes for mistakes
 that are found using these schema, in addition to warnings from the
 dtc compiler.
 
 As usual, many changes are for adding support for additional on-chip
 and on-board components in the machines we already support.
 
 The newly supported SoCs for this release are:
 
  - MStar Infinity2M, a low-end IP camera chip based on a dual-core
    Cortex-A7, otherwise similar to the Infinity chip we already support.
    This is also known as the SigmaStar SSD202D, and we add support for
    the Honestar ssd201htv2 development kit.
 
  - Nuvoton NPCM730, a Cortex-A9 based Baseboard Management Controller
    (BMC), in the same family as the NPCM750. This gets used in the Ampere
    Altra based "Fii Kudo" server and the Quanta GSJ, both of which are
    added as well.
 
  - Broadcom BCM4908, a 64-bit home router chip based on Broadcom's own
    Brahma-B53 CPU. Support is also added for the Asus ROG Rapture
    GT-AC5300 high-end WiFi router based on this chip.
 
  - Mediatek MT8192 is a new SoC based on eight Cortex-A76/A55 cores,
    meant for faster Chromebooks and tablets. It gets added along with
    its reference design.
 
  - Mediatek MT6779 (Helio P90) is a high-end phone chip from last year's
    generation, also added along with its reference board.  This one is
    still based on Cortex-A75/A55.
 
  - Mediatek MT8167 is a version of the already supported MT8516 chip,
    both based on Cortex-A35. It gets added along with the "Pumpkin"
    single board computer, but is likely to also make its way into low-end
    tablets in the future.
 
 For the already supported chips, there are a number of new boards.
 Interestingly there are more 32-bit machines added this time than
 64-bit. Here is a brief list of the new boards:
 
  - Three new Mikrotik router variants based on Marvell Prestera
    98DX3236, a close relative of the more common Armada XP
 
  - A reference board for the Marvell Armada 382
 
  - Three new servers using ASpeed baseboard management controllers,
    the actual machines being from Bytedance, Facebook and IBM,
    and one machine using the Nuvoton NPCM750 BMC.
 
  - The Galaxy Note 10.1 (P4) tablet, using an Exynos 4412.
 
  - The usual set of 32-bit i.MX industrial/embedded hardware:
    * Protonic WD3 (tractor e-cockpit)
    * Kamstrup OMNIA Flex Concentrator (smart grid platform)
    * Van der Laan LANMCU (food storage)
    * Altesco I6P (vehicle inspection stations)
    * PHYTEC phyBOARD-Segin/phyCORE-i.MX6UL baseboard
 
  - DH electronics STM32MP157C DHCOM, a PicoITX carrier board
    for the aleady supported DHCOM module
 
  - Three new Allwinner SoC based single-board computers:
    * NanoPi R1 (H3 based)
    * FriendlyArm ZeroPi (H3 based)
    * Elimo Initium SBC (S3 based)
 
  - Ouya Game Console based on Nvidia Tegra 3
 
  - Version 5 of the already supported Zynq Z-Turn MYIR Board
 
  - LX2162AQDS, a reference platform for NXP Layerscape
    LX2162A, which is a repackaged 16-core LX2160A
 
  - A series of Kontron i.MX8M Mini baseboard/SoM versions
 
  - Espressobin Ultra, a new variant of the popular Armada 3700 based board,
 
  - IEI Puzzle-M801, a rackmount network appliance based on
    Marvell Armada 8040
 
  - Microsoft Lumia 950 XL, a phone
 
  - HDK855 and HDK865 Hardware development kits for Qualcomm
    sm8250 and sm8150, respectively
 
  - Three new board variants of the "Trogdor" Chromebook
    (sc7180)
 
  - New board variants of the Renesas based "Kingfisher" and
    "HiHope" reference boards
 
  - Kobol Helios64, an open source NAS appliance based on Rockchips
    RK3399
 
  - Engicam PX30.Core, a SoM based on Rockchip PX30, along with
    a few carrier boards.
 
 There is one conflict in mt6577_auxadc.txt, which got replaced in
 another tree and modified here, the modification is already part of
 the new file.

a39d2ef78d Qualcomm ARM64 DT updates for 5.11
For SM8250 the recently introduced support for handling boot-loader
 stream mappings in the ARM SMMU allow us to enable this, and thereby USB
 controller and PHY, SDHCI controller and FastRPC, as well as support for
 the SM8250 HDK board has been added. Additionally PRNG and RTC is
 enabled.
 
 Similarly for SM8150, the ARM SMMU could be added which allows the
 secondary USB controller and PHYs, as well as WiFi to be added and
 support for the SM8150 HDK board to be introduced. Additionally
 Coresight and support for the last-level cache controller was added.
 
 MSM8916 finally has VDDCX and VDDMX removed as regulators and are now
 handled by the rpmpd driver for the devices controlling them. The
 Longsheer L8150 gains touchscreen, sensors, vibrator and LED support.
 
 MSM8992 gains USB and SDHCI support as well as an I2C controller and the
 associated RMI4 based touchscreen for the Lumia 950.
 
 MSM8994 also gains USB and SDHCI support, as well as VADC and temp-alarm
 support. Then support for the Lumia 950 XL is added.
 
 SDM845 gains interconnect properties for a number of devices and the
 GENI wrappers gains iommu stream configuration, which means DMA
 operations on e.g. I2C now works. The Lenovo Yoga C630 finally has the
 SMMU enabled, a few fixes and the description of the eDP bridge and
 panel means that the laptop can now boot mainline with working display,
 GPU, WiFi and audio.
 
 SC7180 gains a slew of smaller improvements and fixes.

The QUP nodes are currently defined just as entries in the topology,
but they are not referenced by any of the NoCs. Let's fix this and
"attach" them to their NoCs, so that the QUP drivers are able to use
them as path endpoints and scale their bandwidth.

This is based on the information from the downstream msm-4.9 kernel.
