The RK801 is a PMIC designed for multimedia and handheld devices. It includes: - 4 BUCK regulators (DCDC) - 2 LDO regulators - 1 SWITCH regulator - Interrupt support for power key events The implementation follows the existing rk808 MFD driver architecture and integrates RK801 as a new variant in the RK8XX family. Patch 1 adds the device tree binding documentation for RK801, describing the compatible string, regulators configuration, and example usage. Patch 2 adds the rk801 driver support.
