There are cleanups and minor bugfixes across several SoC specific
drivers, for Qualcomm, Samsung, NXP i.MX, AT91, Tegra, Keystone,
Renesas, ZynqMP
Noteworthy new features are:
- The op-tee firmware driver gains support for asynchronous
notifications from secure-world firmware.
- Qualcomm platforms gain support for new SoC types in various
drivers: power domain, cache controller, RPM sleep, soc-info
- Samsung SoC drivers gain support for new SoCs in ChipID and PMU,
as well as a new USIv2 driver that handles various types of
serial communiction (uart, i2c, spi)
- Renesas adds support for R-Car S4-8 (R8A779F0) in multiple
drivers, as well as memory controller support for RZ/G2L
(R9A07G044).
- Apple M1 gains support for the PMGR power management driver
