Pull SoC driver updates from Arnd Bergmann:
"The driver updates seem larger this time around, with changes is many
of the SoC specific drivers, both the custom drivers/soc ones and the
closely related subsystems (memory, bus, firmware, reset, ...).

The at91 platform gains support for sam9x7 chips in the soc and power
management code. This is the latest variant of one of the oldest still
supported SoC families, using the ARM9 (ARMv5) core.

As usual, the qualcomm snapdragon platform gets a ton of updates in
many of their drivers to add more features and additional SoC support.
Most of these are somewhat firmware related as the platform has a
number of firmware based interfaces to the kernel. A notable addition
here is the inclusion of trace events to two of these drivers.

Herve Codina and Christophe Leroy are now sending updates for
drivers/soc/fsl/ code through the SoC tree, this contains both PowerPC
and Arm specific platforms and has previously been problematic to
maintain. The first update here contains support for newer PowerPC
variants and some cleanups.

The turris mox firmware driver has a number of updates, mostly
cleanups.

The Arm SCMI firmware driver gets a major rework to modularize the
existing code into separately loadable drivers for the various
transports, the addition of custom NXP i.MX9 interfaces and a number
of smaller updates.

The Arm FF-A firmware driver gets a feature update to support the v1.2
version of the specification.

The reset controller drivers have some smaller cleanups and a newly
added driver for the Intel/Mobileye EyeQ5/EyeQ6 MIPS SoCs.

The memory controller drivers get some cleanups and refactoring for
Tegra, TI, Freescale/NXP and a couple more platforms.

Finally there are lots of minor updates to firmware (raspberry pi,
tegra, imx), bus (sunxi, omap, tegra) and soc (rockchips, tegra,
amlogic, mediatek) drivers and their DT bindings"

The main addition this time is the basic support for FF-A v1.2
specification which includes support for newly added:
1. FFA_MSG_SEND_DIRECT_{REQ,RESP}2
2. FFA_PARTITION_INFO_GET_REGS
3. FFA_YIELD support in direct messaging

Apart from these, the changes include support to fetch the Rx/Tx buffer

coding style cleanups.

firmware: arm_ffa: Fetch the Rx/Tx buffer size using ffa_features()

An endpoint can discover the minimum size, maximum size and alignment
boundary for the Rx/Tx buffers by passing the function ID of the
FFA_RXTX_MAP ABI as input in the FFA_FEATURES interface. The maximum
size is an optional field and a value of 0 means that the partition
manager or the hypervisor does not enforce a maximum size.

Use the discovery mechanism and remove the hardcoded 4kB buffer size.
If the discovery fails, it still defaults to 4kB.

firmware: arm_ffa: Add support for FFA_YIELD in direct messaging

Successful completion of both direct messaging function can be indicated
through an invocation of FFA_YIELD or GGA_INTERRUPT by the callee.

FFA_INTERRUPT indicates that the direct request was interrupted and must
be resumed through the FFA_RUN interface which is already done in the
driver.

FFA_YIELD indicates that the receiver endpoint has transitioned to the
blocked runtime state and must be resumed through the FFA_RUN interface.
However, the way receiver endpoint gets unblocked is implementation
defined. So, the driver just sleeps for 1 - 2ms and issues FFA_RUN. It
can return to the caller with FFA_YIELD is the receiver endpoint is still
blocked.

firmware: arm_ffa: Add support for FFA_MSG_SEND_DIRECT_{REQ,RESP}2

FFA_MSG_SEND_DIRECT_{REQ,RESP} supported only x3-x7 to pass implementation
defined values as part of the message. This may not be sufficient sometimes
and also it would be good to use all the registers supported by SMCCC v1.2
(x0-x17) for such register based communication.

Also another limitation with the FFA_MSG_SEND_DIRECT_{REQ,RESP} is the
ability to target a specific service within the partition based on it's
UUID.

In order to address both of the above limitation, FF-A v1.2 introduced
FFA_MSG_SEND_DIRECT_{REQ,RESP}2 which has the ability to target the
message to a specific service based on its UUID within a partition as
well as utilise all the available registers(x4-x17 specifically) for
the communication.

This change adds support for FFA_MSG_SEND_DIRECT_REQ2 and
FFA_MSG_SEND_DIRECT_RESP2.

firmware: arm_ffa: Add support for FFA_PARTITION_INFO_GET_REGS

FF-A v1.2 introduced FFA_PARTITION_INFO_GET_REGS which is similar to
FFA_PARTITION_INFO_GET except that the former uses the registers to
get the required information instead of the Rx buffer which the latter
uses.

We need to first check if the platform supports this new API using
FFA_FEATURES so that we can fallback to the FFA_PARTITION_INFO_GET
(which is mandatory) if FFA_PARTITION_INFO_GET_REGS is not implemented.
