The MUIC and Fuel-Gauge units + are separate from the main MFD, having their own i2c lines, while the + LED driver, regulators and charger are sharing the main i2c bus of the MFD. + +properties: + compatible: + const: + - siliconmitus,sm5703-mfd + + reg: + description: + I2C slave address. + maxItems: 1 + + regulators: + $ref: ../regulator/siliconmitus,sm5703-regulator.yaml + description: + List of child nodes that specify the regulators. + + reset-gpio: + description: + GPIO which is connected to the MRSTB pin. + maxItems: 1 + +required: + - compatible + - reg + - regulators + +additionalProperties: false + +examples: + - | + i2c { + #address-cells = <1>; + #size-cells = <0>; + + mfd@49 { + compatible = "siliconmitus,sm5703-mfd"; + reg = <0x49>; + + reset-gpio = <&msmgpio 24 GPIO_ACTIVE_HIGH>; + pinctrl-0 = <&mrstb_default>; + + regulator { + compatible = "siliconmitus,sm5703-regulator"; + + regulators { + sm5703_ldo1: ldo1 { + regulator-min-microvolt = <2800000>; + regulator-max-microvolt = <2800000>; + }; + + sm5703_ldo2: ldo2 { + regulator-min-microvolt = <1500000>; + regulator-max-microvolt = <3300000>; + }; + + sm5703_ldo3: ldo3 { + regulator-min-microvolt = <3300000>; + regulator-max-microvolt = <3300000>; + }; + + sm5703_usbldo1: usbldo1 { + regulator-min-microvolt = <4800000>; + regulator-max-microvolt = <4800000>; + }; + + sm5703_usbldo2: usbldo2 { + regulator-min-microvolt = <4800000>; + regulator-max-microvolt = <4800000>; + }; + + sm5703_vbus: vbus { + regulator-min-microvolt = <5000000>; + regulator-max-microvolt = <5000000>; + }; + }; + }; + }; + }; -- 2.35.1
