Adds support for using FF-A [1] as transport to the OP-TEE driver.

Introduces struct optee_msg_param_fmem which carries all information
needed when OP-TEE is calling FFA_MEM_RETRIEVE_REQ to get the shared
memory reference mapped by the hypervisor in S-EL2. Register usage is
also updated to include the information needed.

The FF-A part of this driver is enabled if CONFIG_ARM_FFA_TRANSPORT is

Isolate the ABI based on raw SMCs. Code specific to the raw SMC ABI is
moved into smc_abi.c. This makes room for other ABIs with a clear
separation.

The driver changes to use module_init()/module_exit() instead of
module_platform_driver(). The platform_driver_register() and
platform_driver_unregister() functions called directly to keep the same
behavior. This is needed because module_platform_driver() is based on
module_driver() which can only be used once in a module.

A function optee_rpc_cmd() is factored out from the function
handle_rpc_func_cmd() to handle the ABI independent part of RPC
processing.

This patch is not supposed to change the driver behavior, it's only a
matter of reorganizing the code.

These functions a central to communicating with OP-TEE in secure world
by using the SMC Calling Convention directly.

Qualcomm driver updates for v5.16

This drops the use of power-domains for exposing the load_state from the
QMP driver to clients, to avoid issues related to system suspend.

SMP2P becomes wakeup capable, to allow dying remoteprocs to wake up
Linux from suspend to perform recovery.

It adds RPM power-domain support for SM6350 and MSM8953 and base RPM
support for MSM8953 and QCM2290.

It adds support for MSM8996, SDM630 and SDM660 in the SPM driver, which
will enable the introduction of proper voltage scaling of the CPU
subsystem.

Support for releasing secondary CPUs on MSM8226 is introduced.

The Asynchronous Packet Router (APR) driver is extended to support the
new Generic Packet Router (GPR) variant, which is used to communicate
with the firmware in the new AudioReach audio driver.

Lastly it transitions a number of drivers to safer string functions, as
well as switching things to use devm_platform_ioremap_resource().

Merge tag 'tegra-for-5.16-cpuidle' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into arm/drivers

cpuidle: tegra: Changes for v5.16-rc1

This pulls in the for-5.16/clk and for-5.16/soc branches and uses the
stubs added in them to enable compile testing of the cpuidle driver.
While at it, this also fixes a potential driver probe order race
condition between the PMC and the cpuidle driver.

Merge tag 'tegra-for-5.16-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into arm/drivers

soc/tegra: Changes for v5.16-rc1

This set consists of stub additions to enable compile testing for more
drivers, exposes the PMC's USB regmap on all SoC generations, removes a
state synchronization workaround that is no longer needed and adds an
error reporting driver that can help troubleshoot crashes.

To top it all off, an error handling path in the powergating code is
fixed and the devm_platform_ioremap_resource() function is used to
remove some boilerplate code.

platform_get_resource() and devm_ioremap_resource() separately.

Add a driver to hook into panic notifiers and print machine check
status for debugging. Status information is retrieved via SMC. This
is supported by upstream ARM Trusted Firmware.
