Binding for Maxim MAX77802 regulators
This is a part of device tree bindings of MAX77802 multi-function device.
More information can be found in bindings/mfd/max77802.txt file.
The MAX77802 PMIC has 10 high-efficiency Buck and 32 Low-dropout (LDO)
regulators that can be controlled over I2C.
Following properties should be present in main device node of the MFD chip.
Optional node:
- regulators : The regulators of max77802 have to be instantiated
under subnode named "regulators" using the following format.
regulator-name {
standard regulator constraints....
};
refer Documentation/devicetree/bindings/regulator/regulator.txt
The regulator node name should be initialized with a string to get matched
with their hardware counterparts as follow. The valid names are:
-LDOn : for LDOs, where n can lie in ranges 1-15, 17-21, 23-30
and 32-35.
example: LDO1, LDO2, LDO35.
-BUCKn : for BUCKs, where n can lie in range 1 to 10.
example: BUCK1, BUCK5, BUCK10.
Example:
max77802@09 {
compatible = "maxim,max77802";
interrupt-parent = <&wakeup_eint>;
interrupts = <26 0>;
reg = <0x09>;
#address-cells = <1>;
#size-cells = <0>;
regulators {
ldo11_reg: LDO11 {
regulator-name = "vdd_ldo11";
regulator-min-microvolt = <1900000>;
regulator-max-microvolt = <1900000>;
regulator-always-on;
};
buck1_reg: BUCK1 {
regulator-name = "vdd_mif";
regulator-min-microvolt = <950000>;
regulator-max-microvolt = <1300000>;
regulator-always-on;
regulator-boot-on;
};
};
