Merge tag 'scmi-updates-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/drivers
ARM SCMI updates for v5.14
- Support for SCMI clocks from the SCMI power domains
- Addition of checks for correct compatibles for shmem devicetree nodes
that were found missing in the process of YAML schema conversion
- Kconfig and associated build fix found when optee transport are being
worked on
- Couple of fixes and cleanups found as with work-in-progress virtio
transport support
The new transports(optee and virtio) themselves are still being worked on
with ongoing reviews, they are not part of this yet
