Rockchip
Many changesets went into improving support for Rockchip RK3588 SoC and RK808 PMIC. Sebastian Reichel submitted a patch series that implemented RK806 PMIC support. This is required for further support of RK3588 and RK3588s-based boards, which use one or two of these chips to supply all the voltages required by modern SoCs. On top of that, he enabled support for these PMICs on one of the initial RK3588 evaluation boards and the Radxa Rock 5B board. Shreeya Patel contributed a patch series for adding ADC support for RK3588 SoC and updating its device tree bindings. Cristian Ciocaltea added a timer and OTP memory support for Rockchip RK3588 SoC, while also providing a few improvements to the existing rockchip-otp driver, as well as a couple of fixes to the ES8316 codec driver, which is used to provide analog audio support for the above mentioned boards. Nicolas Dufresne also made a change to the v4l2 core that ensures correct initialization of bit depth in Rockchip platforms where 10-bit data is stored fully packed. Benjamin Gaignard implemented AV1 stateless decoder for the very same SoC in its Verisilicon media platform drivers set. Last, but not least, Boris Brezillon added support for powering down the memory used by particular power domains via PMU_MEM_PWR_GATE_SFTCON .
