Subject: [PATCH 0/2] Add support for the P1 PMIC from SpacemiT

P1 is a multi-channel power management IC from SpacemiT.[1]

It has 6 constant-on-time (COT) buck converters, 12 low-dropout
regulators (LDOs), as well as pinctrl, RTC, and pwrkey functions.

The datasheet of P1 can be found here. [2]

This series is based on K1 initial series [3] and I2C of K1 series [4].
