Hello,
This series adds reset controllers for the Realtek RTD1295 SoC.
Since there is still no public source code for RTD1295, the individual resets
were derived from reset-names in the vendor DT; the implementation was a guess.

RK805 is one of Rockchip PMICs family, it has 2 output only GPIOs.
This driver is also designed for other Rockchip PMICs to expend.
Different PMIC maybe have different pin features, for example,
RK816 has one pin which can be used for TS or GPIO(input/out).
The mainly difference between PMICs pins
This driver provides a input driver for the power
