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
relevant parties.

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.

Similar to commit a6c30873ee ("ARM: 8989/1: use .fpu assembler
directives instead of assembler arguments").
GCC and GNU binutils support setting the "sub arch" via -march=,
-Wa,-march, target function attribute, and .arch assembler directive.
Clang was missing support for -Wa,-march=, but this was implemented in
clang-13.
The behavior of both GCC and Clang is to
prefer -Wa,-march= over -march= for assembler and assembler-with-cpp
sources, but Clang will warn about the -march= being unused.
clang: warning: argument unused during compilation: '-march=armv6k'
[-Wunused-command-line-argument]
Since most assembler is non-conditionally assembled with one sub arch
(modulo arch/arm/delay-loop.S which conditionally is assembled as armv4
based on CONFIG_ARCH_RPC, and arch/arm/mach-at91/pm-suspend.S which is
conditionally assembled as armv7-a based on CONFIG_CPU_V7), prefer the
.arch assembler directive.
Add a few more instances found in compile testing as found by Arnd and
Nathan.

This patch introduces support for setting the wait-pin polarity as well
as using the same wait-pin for different CS regions.
The waitpin polarity can be configured via the WAITPIN<X>POLARITY bits
in the GPMC_CONFIG register. This is currently not supported by the
driver. This patch adds support for setting the required register bits
with the "ti,wait-pin-polarity" dt-property.
The wait-pin can also be shared between different CS regions for special
usecases. Therefore GPMC must keep track of wait-pin allocations, so it
knows that either GPMC itself or another driver has the ownership.

The SPI Multi I/O Bus Controller (RPC-IF) on R-Car Gen4 SoCs is very
similar to the RPC-IF on R-Car Gen3 SoCs. It does support four instead
of three bits of strobe timing adjustment (STRTIM), and thus requires a
new mask and new settings.
Inspired by a patch in the BSP by Cong Dang.

According to the datasheet, HS bit should be specified to 1 when using
DMA transfer. As DMA transfer is not supported, it should be cleared to
0.
Previously, the driver relied on the HS bit being cleared by prior
firmware but this is not always the case.
Fix this by ensuring the bit is cleared during hardware initialization.

The next generation (revision 1) of the DFL EMIF feature device requires
support for more than 4 memory banks. It does not support the selective
clearing of memory banks. A capability register replaces the previous
control register, and contains a bitmask to indicate the presence of each
memory bank. This bitmask aligns with the previous control register
bitmask that served the same purpose. The control and capability
registers are treated like a C Union structure in order to support both
the new and old revisions of the EMIF device.

The MediaTek Helio X10 (MT6795) SoC has 5 LARBs and one common SMI
instance without any sub-common and without GALS.
While the smi-common configuration is specific to this SoC, on the
LARB side, this is similar to MT8173, in the sense that it doesn't
need the port in LARB, and the register layout is also compatible
with that one, which makes us able to fully reuse the smi-larb

There are minor updates to SoC specific drivers for chips by Rockchip,
Samsung, NVIDIA, TI, NXP, i.MX, Qualcomm, and Broadcom. Noteworthy
driver changes include:
- Several conversions of DT bindings to yaml format.
- Renesas adds driver support for R-Car V4H, RZ/V2M and RZ/G2UL SoCs.
- Qualcomm adds a bus driver for the SSC (Snapdragon Sensor Core),
and support for more chips in the RPMh power domains and the soc-id.
- NXP has a new driver for the HDMI blk-ctrl on i.MX8MP.
- Apple M1 gains support for the on-chip NVMe controller, making it
possible to finally use the internal disks. This also includes SoC
drivers for their RTKit IPC and for the SART DMA address filter.
For other subsystems that merge their drivers through the SoC tree,
we have
- Firmware drivers for the ARM firmware stack including TEE, OP-TEE,
SCMI and FF-A get a number of smaller updates and cleanups. OP-TEE
now has a cache for firmware argument structures as an optimization,
and SCMI now supports the 3.1 version of the specification.
- Reset controller updates to Amlogic, ASpeed, Renesas and ACPI drivers
- Memory controller updates for Tegra, and a few updates for other
platforms.

Add support for logging memory controller errors on Tegra186, Tegra194
and Tegra234. On these SoCs, interrupts can occur on multiple channels.
Add support required to read the status of interrupts across multiple
channels, log and clear them.
Also add new interrupts supported on these SoCs.

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.

is similar to the version found on earlier SoCs but supports a number of
new memory clients.

Allow OMAP_GPMC to be built as a module.
When building this driver as a module, the symbol
'of_default_bus_match_table' will not be found as it is not being
exported.
The of_match_node() call is redundant anyways as
of_platform_default_populate() already takes care of matching with
'of_default_bus_match_table'. So get rid of that call. This will also
resolve the module build failure.
Move compatible match table to the end where it is usually expected.
