This patch series adds support for the Rockchip RK801 Power Management
Integrated Circuit (PMIC) to the Linux kernel.
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.
