Merge tag 'v5.13-next-soc' of https://git.kernel.org/pub/scm/linux/kernel/git/matthias.bgg/linux into arm/drivers
devapc:
- add missing MODULE_DEVICE_TABLE to fix modalias
mkt-pm-domains:
- register smi node as regmap and not as syscon
- prepare-enable and unprepare-disable dependent clocks
pwrap:
- add support for MT8195
