9eab43facd soc: renesas: ARCH_R9A07G043 depends on !RISCV_ISA_ZICBOM
ARCH_R9A07G043 has its own non-standard global pool based DMA coherent
allocator, which conflicts with the remap based RISCV_ISA_ZICBOM version.
Add a proper dependency.

Pull ARM SoC fixes from Arnd Bergmann:
 "AngeloGioacchino Del Regno is stepping in as co-maintainer for the
  MediaTek SoC platform and starts by sending some dts fixes for the
  mt8195 platform that had been pending for a while.

  On the ixp4xx platform, Krzysztof Halasa steps down as co-maintainer,
  reflecting that Linus Walleij has been handling this on his own for
  the past few years.

  Generic RISC-V kernels are now marked as incompatible with the RZ/Five
  platform that requires custom hacks both for managing its DMA bounce
  buffers and for addressing low virtual memory.

 Finally, there is one bugfix for the AMDTEE firmware driver to prevent
 a use-after-free bug"

Randy reported a randconfig build issue against linux-next:

    WARNING: unmet direct dependencies detected for ERRATA_ANDES
      Depends on [n]: RISCV_ALTERNATIVE [=n] && RISCV_SBI [=y]
      Selected by [y]:
      - ARCH_R9A07G043 [=y] && SOC_RENESAS [=y] && RISCV [=y] && NONPORTABLE [=y] && RISCV_SBI [=y]

       59 | void __init_or_module andes_errata_patch_func(struct alt_entry *begin, struct alt_entry *end,

On RISC-V, alternatives are not usable in XIP kernels, which this
randconfig happened to select.  Rather than add a check for whether
alternatives are available before selecting the ERRATA_ANDES config
option, rework the R9A07G043 Kconfig entry to depend on the
configuration options required to support its non-standard cache
coherency implementation.

Without these options enabled, the SoC is effectively non-functional to
begin with, so there's an extra benefit in preventing the creation of
non-functional kernels.

The "if RISCV_DMA_NONCOHERENT" can be dropped, as ERRATA_ANDES_CMO will
select it.

c1ec4b450a soc: renesas: Make ARCH_R9A07G043 (riscv version) depend on NONPORTABLE
Drew found "CONFIG_DMA_GLOBAL_POOL=y causes ADMA buffer alloc to fail"
the log looks like:

    mmc0: Unable to allocate ADMA buffers - falling back to standard DMA

The logic is: generic riscv defconfig selects ARCH_RENESAS then
ARCH_R9A07G043 which selects DMA_GLOBAL_POOL, which assumes all
non-dma-coherent riscv platforms have a dma global pool, this assumption
seems not correct. And I believe DMA_GLOBAL_POOL should not be
selected by ARCH_SOCFAMILIY, instead, only ARCH under some specific
conditions can select it globaly, for example NOMMU ARM and so on,
because it's designed for special cases such as "nommu cases where
non-cacheable memory lives in a fixed place in the physical address
map" as pointed out by Robin.

Fix the issue by making ARCH_R9A07G043 (riscv version) depend on
NONPORTABLE, thus generic defconfig won't select ARCH_R9A07G043 by
default. And even for random config case, there will be less debug
effort once we see NONPORTABLE is enabled.

9d1e8275a2 soc: imx8m: Enable OCOTP clock for imx8mm before reading registers
Commit 836fb30949 ("soc: imx8m: Enable OCOTP clock before reading the
register") added configuration to enable the OCOTP clock before
attempting to read from the associated registers.

This same kexec issue is present with the imx8m SoCs that use the
imx8mm_soc_uid function (e.g. imx8mp). This requires the imx8mm_soc_uid
function to configure the OCOTP clock before accessing the associated
registers. This change implements the same clock enable functionality
that is present in the imx8mq_soc_revision function for the
imx8mm_soc_uid function.

c23be918c5 Merge patch series "Add non-coherent DMA support for AX45MP"
Prabhakar <prabhakar.csengg@gmail.com> says:

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

non-coherent DMA support for AX45MP
====================================

On the Andes AX45MP core, cache coherency is a specification option so it
may not be supported. In this case DMA will fail. To get around with this
issue this patch series does the below:

1] Andes alternative ports is implemented as errata which checks if the
IOCP is missing and only then applies to CMO errata. One vendor specific
SBI EXT (ANDES_SBI_EXT_IOCP_SW_WORKAROUND) is implemented as part of
errata.

Below are the configs which Andes port provides (and are selected by
RZ/Five):
      - ERRATA_ANDES
      - ERRATA_ANDES_CMO

OpenSBI patch supporting ANDES_SBI_EXT_IOCP_SW_WORKAROUND SBI is now
part v1.3 release.

2] Andes AX45MP core has a Programmable Physical Memory Attributes (PMA)
block that allows dynamic adjustment of memory attributes in the runtime.
It contains a configurable amount of PMA entries implemented as CSR
registers to control the attributes of memory locations in interest.
OpenSBI configures the PMA regions as required and creates a reserve memory
node and propagates it to the higher boot stack.

Currently OpenSBI (upstream) configures the required PMA region and passes
this a shared DMA pool to Linux.

    reserved-memory {
        #address-cells = <2>;
        #size-cells = <2>;
        ranges;

        pma_resv0@58000000 {
            compatible = "shared-dma-pool";
            reg = <0x0 0x58000000 0x0 0x08000000>;
            no-map;
            linux,dma-default;
        };
    };

The above shared DMA pool gets appended to Linux DTB so the DMA memory
requests go through this region.

3] We provide callbacks to synchronize specific content between memory and
cache.

4] RZ/Five SoC selects the below configs
        - AX45MP_L2_CACHE
        - DMA_GLOBAL_POOL
        - ERRATA_ANDES
        - ERRATA_ANDES_CMO

f8fd5c2483 Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk subsystem updates from Stephen Boyd:
 "This pull request is full of clk driver changes. In fact, there aren't
  any changes to the clk framework this time around. That's probably
  because everyone was on vacation (yours truly included). We did lose a
  couple clk drivers this time around because nobody was using those
  devices. That skews the diffstat a bit, but either way, nothing looks
  out of the ordinary here. The usual suspects are chugging along adding
  support for more SoCs and fixing bugs.

  If I had to choose, I'd say the theme for the past few months has been
  "polish". There's quite a few patches that migrate to
  devm_platform_ioremap_resource() in here. And there's more than a
  handful of patches that move the NR_CLKS define from the DT binding
  header to the driver. There's even patches that migrate drivers to use
  clk_parent_data and clk_hw to describe clk tree topology. It seems
  that the spring (summer?) cleaning bug got some folks, or the
  semiconductor shortage finally hit the software side.

  New Drivers:
   - StarFive JH7110 SoC clock drivers
   - Qualcomm IPQ5018 Global Clock Controller driver
   - Versa3 clk generator to support 48KHz playback/record with audio
     codec on RZ/G2L SMARC EVK

  Removed Drivers:
   - Remove non-OF mmp clk drivers
   - Remove OXNAS clk driver

  Updates:
   - Add __counted_by to struct clk_hw_onecell_data and struct
     spmi_pmic_div_clk_cc
   - Move defines for numbers of clks (NR_CLKS) from DT headers to
     drivers
   - Introduce kstrdup_and_replace() and use it
   - Add PLL rates for Rockchip rk3568
   - Add the display clock tree for Rockchip rv1126
   - Add Audio Clock Generator (ADG) clocks on Renesas R-Car Gen3 and
     RZ/G2 SoCs
   - Convert sun9i-mmc clock to use
     devm_platform_get_and_ioremap_resource()
   - Fix function name in a comment in ccu_mmc_timing.c
   - Parameter name correction for ccu_nkm_round_rate()
   - Implement CLK_SET_RATE_PARENT for Allwinner NKM clocks, i.e.
     consider alternative parent rates when determining clock rates
   - Set CLK_SET_RATE_PARENT for Allwinner A64 pll-mipi
   - Support finding closest (as opposed to closest but not higher)
     clock rate for NM, NKM, mux and div type clocks, as use it for
     Allwinner A64 pll-video0
   - Prefer current parent rate if able to generate ideal clock rate for
     Allwinner NKM clocks
   - Clean up Qualcomm SMD RPM driver, with interconnect bus clocks
     moved out to the interconnect drivers
   - Fix various PM runtime bugs across many Qualcomm clk drivers
   - Migrate Qualcomm MDM9615 is to parent_hw and parent_data
   - Add network related resets on Qualcomm IPQ4019
   - Add a couple missing USB related clocks to Qualcomm IPQ9574
   - Add missing gpll0_sleep_clk_src to Qualcomm MSM8917 global clock
     controller
   - In the Qualcomm QDU1000 global clock controller, GDSCs, clkrefs,
     and GPLL1 are added, while PCIe pipe clock, SDCC rcg ops are
     corrected
   - Add missing GDSCs to and correct GDSCs for the SC8280XP global
     clock controller driver
   - Support retention for the Qualcomm SC8280XP display clock
     controller GDSCs.
   - Qualcommm's SDCC apps_clk_src is marked with CLK_OPS_PARENT_ENABLE
     to fix issues with missing parent clocks across sc7180, sm7150,
     sm6350 and sm8250, while sm8450 is corrected to use floor ops
   - Correct Qualcomm SM6350 GPU clock controller's clock supplies
   - Drop unwanted clocks from the Qualcomm IPQ5332 GCC driver
   - Add missing OXILICX GDSC to Qualcomm MSM8226 GCC
   - Change the delay in the Qualcomm reset controller to fsleep() for
     correctness
   - Extend the Qualcomm SM83550 Video clock controller to support
     SC8280XP
   - Add graphics clock support on Renesas RZ/G2M, RZ/G2N, RZ/G2E, and

Qualcomm driver updates for v6.6

Compatible and clock handling in the Qualcomm SCM driver is cleaned up,
together with a couple stylistic cleanups and transition to mark
exported symbols GPL only.

An abstraction for the RPM subsystem is introduced, to make align the
structure of the SMD and GLINK nodes thereof with the structure when a
remoteproc is involved. This is done to facilitate associating
additional entities with the RPM subsystem.

The qmp_send() API is modified to not expose hardware requirements onto
the client drivers, and then further extended to allow command
formatting directly in the API, to facilitate this typical use case.

In the Qualcomm Command DB driver, NUL characters previously included in
identifiers are dropped from the debugfs, to facilitate scripting.

The thresholds of the BWMON driver are simplified to avoid hard coded
starting values.

The OCMEM driver is updated with some cleanups and fixes, and addition
of MSM8226 support.

PMIC_GLINK gains support for retimer switches, safe mode is selected
when the cable is disconnected from altmode and the same is enabled for
SM8550.

An off-by-one string length check is corrected in the QMI encoder
decoder library.

The RPMh tracepoints are extended to include the state of the request,
to provide needed context in the traced events.

The series from Ulf creating a genpd framework is integrated, to
facilitate the other changes to the cpr, rpmpd and rpmhpd driver.
SDX75 support is added to the rpmhpd driver, and the rpmpd driver is
extended with the same sync_state logic found in the rpmhpd driver.

The socinfo driver gains knowledge about SM4450 and SM7125, the IPQ5019
platform is dropped.

Clock handling in the GSBI driver is cleaned up with the use of
devm_clk_get_enabled().

The list of VMIDs defined for the SCM assign memory interface is
extended.

59e0910083 soc: qcom: aoss: Move length requirements from caller
The existing implementation of qmp_send() requires the caller to provide
a buffer which is of word-aligned. The underlying reason for this is
that message ram only supports word accesses, but pushing this
requirement onto the clients results in the same boiler plate code
sprinkled in every call site.

By using a temporary buffer in qmp_send() we can hide the underlying
hardware limitations from the clients and allow them to pass their
NUL-terminates C string directly.

5df5b2e047 soc: fsl: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.
