MediaTek MT6397/MT6323 Multifunction Device Driver
MT6397/MT6323 is a multifunction device with the following sub modules:
- Regulator
- RTC
- Audio codec
- GPIO
- Clock
- LED
It is interfaced to host controller using SPI interface by a proprietary hardware
called PMIC wrapper or pwrap. MT6397/MT6323 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" or "mediatek,mt6323"
Optional subnodes:
- rtc
Required properties:
- compatible: "mediatek,mt6397-rtc"
- regulators
Required properties:
- compatible: "mediatek,mt6397-regulator"
see Documentation/devicetree/bindings/regulator/mt6397-regulator.txt
- compatible: "mediatek,mt6323-regulator"
see Documentation/devicetree/bindings/regulator/mt6323-regulator.txt
- codec
Required properties:
- compatible: "mediatek,mt6397-codec"
- clk
Required properties:
- compatible: "mediatek,mt6397-clk"
- led
Required properties:
- compatible: "mediatek,mt6323-led"
see Documentation/devicetree/bindings/leds/leds-mt6323.txt
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>;
};
};
};
};
