    +MediaTek MT6397 Multifunction Device Driver
    +
    +MT6397 is a multifunction device with the following sub modules:
    +- Regulator
    +- RTC
    +- Audio codec
    +- GPIO
    +- Clock
    +
    +It is interfaced to host controller using SPI interface by a proprietary hardware
    +called PMIC wrapper or pwrap. MT6397 MFD is a child device of pwrap.
    +See the following for pwarp node definitions:
    +Documentation/devicetree/bindings/soc/pwrap.txt
    +
    +This document describes the binding for MFD device and its sub module.
    +
    +Required properties:
    +compatible: "mediatek,mt6397"
    +
    +Optional subnodes:
    +
    +- rtc
    + Required properties:
    + - compatible: "mediatek,mt6397-rtc"
    +- regulators
    + Required properties:
    + - compatible: "mediatek,mt6397-regulator"
    + see Documentation/devicetree/bindings/regulator/mt6397-regulator.txt
    +- codec
    + Required properties:
    + - compatible: "mediatek,mt6397-codec"
    +- clk
    + Required properties:
    + - compatible: "mediatek,mt6397-clk"
    +
    +Example:
    + pwrap: pwrap@1000f000 {
    + compatible = "mediatek,mt8135-pwrap";
    +
    + ...
    +
    + pmic {
    + compatible = "mediatek,mt6397";
    +
    + codec: mt6397codec {
    + compatible = "mediatek,mt6397-codec";
    + };
    +
    + regulators {
    + compatible = "mediatek,mt6397-regulator";
    +
    + mt6397_vpca15_reg: buck_vpca15 {
    + regulator-compatible = "buck_vpca15";
    + regulator-name = "vpca15";
    + regulator-min-microvolt = <850000>;
    + regulator-max-microvolt = <1400000>;
    + regulator-ramp-delay = <12500>;
    + regulator-always-on;
    + };
    +
    + mt6397_vgp4_reg: ldo_vgp4 {
    + regulator-compatible = "ldo_vgp4";
    + regulator-name = "vgp4";
    + regulator-min-microvolt = <1200000>;
    + regulator-max-microvolt = <3300000>;
    + regulator-enable-ramp-delay = <218>;
    + };
    + };
    + };
    + };
