Pull SoC driver updates from Arnd Bergmann:
"The SoC driver changes once more consist of many small fixes and
cleanups, that are to a large part the result of automated testing.

On platform specific drivers, this includes SoC specific code for
xilinx, freescale/nxp, qualcomm, TI, aspeed, omap, tegra, samsung,
rockchip, renesas, ixp4xx. In firmware drivers, we see a similar
picture for SCMI and qcomtee.

Aside from these, we see actual new hardware support in a few areas:

- The Apple platform gets a new driver for low power states

- Updates to Qualcomm platform drivers add several new hardware
specific features and additional SoCs.

- Amlogic SoC support for A1 and T7 is added

- The Mediatek MMSYS driver is refactored as a cleanup"

Qualcomm driver updates for v7.3

Add Maili platform bindings for SCM, IMEM, AOSS, and PMIC GLINK. Add
Shikra IMEM, RPM SMD, LLCC, and UBWC support, including handling for
firmware-configured LLCC ECC interrupts.

Add the generic Peripheral Authentication Service with SCM and OP-TEE
backends, and migrate the MSM DRM and IPA drivers to it.

Add SCM SMC-call tracepoints and configurable minidump delivery through
always-on SRAM. Correct SCM download-mode pointer ordering and improve
download-mode probe diagnostics.

Rework the UBWC configuration database and add Milos and Shikra
configuration. Add protection-domain mappings for SA8775P and QCS8300,
support newer ICE versions, Hawi subsystem statistics, and SDM850
identification.

Simplify Qualcomm SoC Kconfig selection and architecture dependencies.
Use managed resources in EBI2 and RPMh RSC probe paths to correct cleanup
on failures.

firmware: qcom: Add a generic PAS service

Qcom platforms has the legacy of using non-standard SCM calls
splintered over the various kernel drivers. These SCM calls aren't
compliant with the standard SMC calling conventions which is a
prerequisite to enable migration to the FF-A specifications from Arm.

OP-TEE as an alternative trusted OS to Qualcomm TEE (QTEE) can't
support these non-standard SCM calls. And even for newer architectures
using S-EL2 with Hafnium support, QTEE won't be able to support SCM
calls either with FF-A requirements coming in. And with both OP-TEE
and QTEE drivers well integrated in the TEE subsystem, it makes further
sense to reuse the TEE bus client drivers infrastructure.

The added benefit of TEE bus infrastructure is that there is support
for discoverable/enumerable services. With that client drivers don't
have to manually invoke a special SCM call to know the service status.

So enable the generic Peripheral Authentication Service (PAS) provided
by the firmware. It acts as the common layer with different TZ
backends plugged in whether it's an SCM implementation or a proper
TEE bus based PAS service implementation.
