- MAXIM, MAX77686 regulators
- This device uses two drivers:
- - drivers/power/pmic/max77686.c (as parent I/O device)
- - drivers/power/regulator/max77686.c (for child regulators)
- This file describes the binding info for the REGULATOR driver.
- First, please read the binding info for the pmic:
- - doc/device-tree-bindings/pmic/max77686.txt
- Required subnode:
- - voltage-regulators: required for the PMIC driver
- Required properties:
- - regulator-name: used for regulator uclass platform data '.name'
- Optional:
- - regulator-min-microvolt: minimum allowed Voltage to set
- - regulator-max-microvolt: minimum allowed Voltage to set
- - regulator-always-on: regulator should be never disabled
- - regulator-boot-on: regulator should be enabled by the bootloader
- Example:
- (subnode of max77686 pmic node)
- voltage-regulators {
- ldo1 {
- regulator-name = "VDD_ALIVE_1.0V";
- regulator-min-microvolt = <1000000>;
- regulator-max-microvolt = <1000000>;
- regulator-always-on;
- regulator-boot-on;
- };
- ldo2 {
- regulator-name = "VDDQ_VM1M2_1.2V";
- regulator-min-microvolt = <1200000>;
- regulator-max-microvolt = <1200000>;
- regulator-always-on;
- regulator-boot-on;
- };
- .
- .
- .
- ldo26 {
- regulator-name = "nc";
- regulator-min-microvolt = <3000000>;
- regulator-max-microvolt = <3000000>;
- regulator-always-on;
- regulator-boot-on;
- };
- buck1 {
- regulator-compatible = "BUCK1";
- regulator-name = "VDD_MIF_1.0V";
- regulator-min-microvolt = <8500000>;
- regulator-max-microvolt = <1100000>;
- regulator-always-on;
- regulator-boot-on;
- };
- .
- .
- .
- buck9 {
- regulator-compatible = "BUCK9";
- regulator-name = "nc";
- regulator-min-microvolt = <1200000>;
- regulator-max-microvolt = <1200000>;
- };
- };
