Log:
MFC r341141-r341143, r341255
r341141:
rk_clk_composite: Fix set_mux
Pointy Hat: manu
r341142:
Add RK805 PMIC Support
RK805 is the companion PMIC for RK3328 SoC.
Add a driver for it with most of it's regulators supported.
r341143:
arm64: Add rk_i2c and rk805 to GENERIC
r341255:
arm64: rockchip: armclk: Do not change parent freq if CLK_SET_DRYRUN is set
