Merge tag 'scmi-updates-5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/drivers
ARM SCMI updates/fixes for v5.4
Handful of fixes/updates including:
1. SCMI v2.0(recently released) support for:
- Performance protocol fast channels
- Reset Management Protocol
2. SCMI infrastructure/core support for recieve(Rx) channels,
asynchronous commands and delayed response
3. Usage of asynchronous commands for clock rate setting and sensor
reading based on the attributes read from the firmware
4. Miscellaneous cleanups(typos, naming alignment with specification,
and SPDX License identifier)
5. Couple of fixes: removal of extra check for invalid length and
additional check to ensure platform/firmware has released shared
memory before using it in OSPM
