b232537074 soc: ti: omap-prm: Fix external abort for am335x pruss
Starting with v5.15-rc1, we may now see some am335x beaglebone black
device produce the following error on pruss probe:

Unhandled fault: external abort on non-linefetch (0x1008) at 0xe0326000

This has started with the enabling of pruss for am335x in the dts files.

Turns out the is caused by the PRM reset handling not waiting for the
reset bit to clear. To fix the issue, let's always wait for the reset
bit to clear, even if there is a separate reset status register.

We attempted to fix a similar issue for dra7 iva with a udelay() in
commit effe89e400 ("soc: ti: omap-prm: Fix occasional abort on reset
deassert for dra7 iva"). There is no longer a need for the udelay()
for dra7 iva reset either with the check added for reset bit clearing.

ed4520d6a1 soc: ti: Remove pm_runtime_irq_safe() usage for smartreflex
For the smartreflex device, we need to disable smartreflex on SoC idle,
and have been using pm_runtime_irq_safe() to do that. But we want to
remove the irq_safe usage as PM runtime takes a permanent usage count
on the parent device with it.

In order to remove the need for pm_runtime_irq_safe(), let's gate
the clock directly in the driver. This removes the need to call PM runtime
during idle, and allows us to switch to using CPU_PM in the following
patch.

Note that the smartreflex interconnect target module is configured for smart
idle, but the clock does not have autoidle capability, and needs to be gated
manually. If the clock supported autoidle, we would not need to even gate
the clock.

With this change, we can now remove the related quirk flags for ti-sysc
also.

22ea87ef3f soc: ti: pruss: Enable support for ICSSG subsystems on K3 AM64x SoCs
The K3 AM64x family of SoCs have a similar version of the PRU-ICSS (ICSSG)
processor subsystem present on K3 J721E and K3 AM65x SR2.0 SoCs. These SoCs
contain typically two ICSSG instances named ICSSG0 and ICSSG1. The two
ICSSGs are identical to each other for the most part with minor SoC
integration differences and capabilities. SGMII mode is not supported at
all on these SoCs (unlike specific instances on AM65x, J721E). The ICSSG1
also has limited pins connected on some sub-modules compared to ICSSG0.

There is no change in the Interrupt Controller w.r.t either of AM65x or
J721E SoCs. All other integration aspects are also very similar to the
existing SoCs.

The existing pruss platform driver has been updated to support these
similar ICSSG instances through a new AM64x specific compatible.

When devm_ioremap_resource() fails, a clear enough error message will be
printed by its subfunction __devm_ioremap_resource(). The error
information contains the device name, failure cause, and possibly resource

Therefore, remove the error printing here to simplify code and reduce the

bc0b964da3 soc: ti: omap-prm: Allow hardware supported retention when idle
When moving the l4 interconnect instances to probe with simple-pm-bus and
genpd, we will have l4per and core domains stop idling unless we configure
the domain bits to allow retention when idle.

As the TI SoCs have hardware autoidle capabilities, this is safe to do.
The domains will only enter retention on WFI when none of the devices on
the domain block autoidle in the hardware. This follows what we are
already currently doing.

effe89e400 soc: ti: omap-prm: Fix occasional abort on reset deassert for dra7 iva
On reset deassert, we must wait a bit after the rstst bit change before
we allow clockdomain autoidle again. Otherwise we get the following oops
sometimes on dra7 with iva:

Unhandled fault: imprecise external abort (0x1406) at 0x00000000
44000000.ocp:L3 Standard Error: MASTER MPU TARGET IVA_CONFIG (Read Link):

It is unclear what all devices this might affect, but presumably other
devices with the rstst bit too can be affected. So let's just enable the
delay for all the devices with rstst bit for now. Later on we may want to
limit the list to the know affected devices if needed.

a249ca66d1 soc: ti: omap-prm: Fix reboot issue with invalid pcie reset map for dra7
Yongqin Liu <yongqin.liu@linaro.org> reported an issue where reboot hangs
on beagleboard-x15. This started happening after commit 7078a5ba7a
("soc: ti: omap-prm: Fix boot time errors for rst_map_012 bits 0 and 1").

We now assert any 012 type resets on init to prevent unconfigured
accelerator MMUs getting enabled on init depending on the bootloader or
kexec configured state.

Turns out that we now also wrongly assert dra7 l3init domain PCIe reset
bits causing a hang during reboot. Let's fix the l3init reset bits to
use a 01 map instead of 012 map. There are only two rstctrl bits and not
three. This is documented in TRM "Table 3-1647. RM_PCIESS_RSTCTRL".

7078a5ba7a soc: ti: omap-prm: Fix boot time errors for rst_map_012 bits 0 and 1
We have rst_map_012 used for various accelerators like dsp, ipu and iva.
For these use cases, we have rstctrl bit 2 control the subsystem module
reset, and have and bits 0 and 1 control the accelerator specific
features.

If the bootloader, or kexec boot, has left any accelerator specific
reset bits deasserted, deasserting bit 2 reset will potentially enable
an accelerator with unconfigured MMU and no firmware. And we may get
spammed with a lot by warnings on boot with "Data Access in User mode
during Functional access", or depending on the accelerator, the system
can also just hang.

This issue can be quite easily reproduced by setting a rst_map_012 type
rstctrl register to 0 or 4 in the bootloader, and booting the system.

Let's just assert all reset bits for rst_map_012 type resets. So far
it looks like the other rstctrl types don't need this. If it turns out
that the other type rstctrl bits also need reset on init, we need to
add an instance specific reset mask for the bits to avoid resetting
unwanted bits.

accefff5b5 ARM: SoC updates for OMAP GenPD
These are additional updates for the power domain support on OMAP,
 moving to an implementation based on device tree information instead of
 SoC specific code. This is the latest step in the ongoing process for
 moving code out of arch/arm/mach-omap2.
 
 I kept this separate from the other driver changes since it touches
 code in multiple areas.
 
 There is one conflict in the dra7.dts file, which adds another node
 in a different branch. Watch out for adding the trailing '};'
 both times.

Pull ARM SoC OMAP GenPD updates from Arnd Bergmann:
 "These are additional updates for the power domain support on OMAP,
  moving to an implementation based on device tree information instead
  of SoC specific code. This is the latest step in the ongoing process
  for moving code out of arch/arm/mach-omap2.

  I kept this separate from the other driver changes since it touches
  code in multiple areas"

d782298c6f soc: ti: k3-ringacc: add AM64 DMA rings support.
The DMAs in AM64 have built in rings compared to AM654/J721e/J7200 where a
separate and generic ringacc is used.

The ring SW interface is similar to ringacc with some major architectural
differences, like

They are part of the DMA (BCDMA or PKTDMA).

They are dual mode rings are modeled as pair of Rings objects which has
common configuration and memory buffer, but separate real-time control
register sets for each direction mem2dev (forward) and dev2mem (reverse).

The ringacc driver must be initialized for DMA rings use with
k3_ringacc_dmarings_init() as it is not an independent device as ringacc
is.

AM64 rings must be requested only using k3_ringacc_request_rings_pair(),
and forward ring must always be initialized/configured. After this any
other Ringacc APIs can be used without any callers changes.

Driver changes for omaps for genpd for v5.11 merge window

This series of changes allows booting am335x with genpd and
device tree data without the legacy platform data. Also at
least am437x can be booted with gendp with power domain and
dts data. The SoC specific dts changes will be a separate
pull request.

We need the following driver changes merged before the dts
changes can be done:

- platform code needs a few improvments to probe l4_wkup first
  for clocks, and to bail out when there is no platform data

- ti-sysc driver needs a non-urgent fix for asserting rstctrl
  reset only after disabling the clocks, to probe modules with
  no known control registers, and added quirk handling for gpmc
  devices

- omap-prm driver needs a non-urgent fix for reset status bit,
  support added for pm_clk, and then we add the rest of am335x
  power domain data

- clock driver for am335x needs to keep l3_main clock enabled
  with genpd for suspend and resume to work

- wkup_m3 remoteproc driver needs support added for reset
  control if available instead of the legacy pdata callbacks

- pm33xx driver needs PM runtime support added for genpd

The am335x specific driver changes for the clock, wkup_m3,
pm33xx and remoteproc drivers are quite trivial and have not
caused merge conflicts in Linux next. I did not get acks for
these changes except from Santosh but had already pushed out
the branch already at that point. So I've added the related
driver maintainers to Cc.

b4fa73358c soc: ti: Fix reference imbalance in knav_dma_probe
The patch fix two reference leak.

  1) pm_runtime_get_sync will increment pm usage counter even it
     failed. Forgetting to call put operation will result in
     reference leak.

  2) The pm_runtime_enable will increase power disable depth. Thus
     a pairing decrement is needed on the error handling path to
     keep it balanced.

We fix it by: 1) adding call pm_runtime_put_noidle or
pm_runtime_put_sync in error handling. 2) adding pm_runtime_disable
in error handling, to keep usage counter and disable depth balanced.

Additionally, proceeding with empty device data is valid (e.g. in case

176958dd8e soc: ti: omap-prm: Add pm_clk for genpd
In order to probe l3 and l4 interconnects with simple-pm-bus, we want
genpd to manage the clocks for the interconnects. For interconnect target
modules, we already have ti-sysc manage the clocks so let's skipe managing
clocks for ti-sysc modules.

If a rstctrl reset bit is already deasserted, we can just bail out early
not wait for rstst to clear. Otherwise we can have deassert fail for
already deasserted resets.

8c42379e40 soc: ti: k3-ringacc: Use correct device for allocation in RING mode
In RING mode the ringacc does not access the ring memory. In this access
mode the ringacc coherency does not have meaning.

If the ring is configured in RING mode, then the ringacc itself will not
access to the ring memory. Only the requester (user) of the ring is going
to read/write to the memory.
Extend the ring configuration parameters with a device pointer to be used
for DMA API when the ring is configured in RING mode.

Extending the ring configuration struct will allow per ring selection of
device to be used for allocation, thus allowing per ring coherency.

To avoid regression, fall back to use the ringacc dev in case the alloc_dev
is not provided.

e731f3146f ARM: SoC platform updates
SoC changes, a substantial part of this is cleanup of some of the older
 platforms that used to have a bunch of board files. In particular:
 
  - Removal of non-DT i.MX platforms that haven't seen activity in years,
    it's time to remove them.
  - A bunch of cleanup and removal of platform data for TI/OMAP platforms,
    moving over to genpd for power/reset control (yay!)
  - Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them
    closer to multiplatform support (not quite there yet, but getting
    close).
 
 THere are a few other changes too, smaller fixlets, etc. For new
 platform support, the primary ones re:
 
  - New SoC: Hisilicon SD5203, ARM926EJ-S platform.
  - Cpufreq support for i.MX7ULP
