+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>;
+ };
+ };
+ };
+ };
