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 MFD core support for RK801, including device detection and register definitions. Patch 3 adds the regulator driver support for RK801, implementing the 4 BUCK regulators, 2 LDO regulators, and 1 SWITCH regulator. Changes in v2: - Include all necessary To/Cc entries - Rename pmic/regulator names from uppercase to lowercase(dcdc[1-4]|ldo[1-2]|switch) to align with DT coding style - Drop 'rockchip,system-power-controller' - Remove unused 'pwrctrl-gpios' from DT binding example - Split regulator support into a separate patch (was part of mfd patch in v1) Joseph Chen (3): dt-bindings: mfd: Add rk801 binding mfd: rk8xx: Add RK801 support regulator: rk808: Add RK801 support .../bindings/mfd/rockchip,rk801.yaml | 197 ++++++++++++++ drivers/mfd/Kconfig | 6 +- drivers/mfd/rk8xx-core.c | 81 ++++++ drivers/mfd/rk8xx-i2c.c | 33 ++- drivers/regulator/rk808-regulator.c | 243 ++++++++++++++++++ include/linux/mfd/rk808.h | 118 +++++++++ 6 files changed, 674 insertions(+), 4 deletions(-) create mode 100644 Documentation/devicetree/bindings/mfd/rockchip,rk801.yaml -- 2.25.1
