SY8106A Voltage regulator
Required properties:
- compatible: Must be "silergy,sy8106a"
- reg: I2C slave address - must be <0x65>
- silergy,fixed-microvolt - the voltage when I2C regulating is disabled (set
by external resistor like a fixed voltage)
Any property defined as part of the core regulator binding, defined in
./regulator.txt, can also be used.
Example:
sy8106a {
compatible = "silergy,sy8106a";
reg = <0x65>;
regulator-name = "sy8106a-vdd";
silergy,fixed-microvolt = <1200000>;
regulator-min-microvolt = <1000000>;
regulator-max-microvolt = <1400000>;
regulator-boot-on;
regulator-always-on;
};
