- Sandbox, PMIC regulators
- This device uses two drivers:
- - drivers/power/pmic/sandbox.c (as parent I/O device)
- - drivers/power/regulator/sandbox.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/sandbox.txt
- Required subnodes:
- - ldoN { };
- - buckN { };
- The sandbox PMIC can support: ldo1, ldo2, buck1, buck2.
- For each PMIC's regulator subnode, there is one required property:
- - 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-min-microamps: minimum allowed Current limit to set (LDO1/BUCK1)
- - regulator-max-microamps: minimum allowed Current limit to set (LDO1/BUCK1)
- - regulator-always-on: regulator should be never disabled
- - regulator-boot-on: regulator should be enabled by the bootloader
- Example PMIC's regulator subnodes:
- ldo1 {
- regulator-name = "VDD_1.0V";
- regulator-min-microvolt = <1000000>;
- regulator-max-microvolt = <1200000>;
- regulator-min-microamps = <100000>;
- regulator-max-microamps = <400000>;
- regulator-always-on;
- };
- buck2 {
- regulator-name = "VDD_1.8V";
- regulator-min-microvolt = <1800000>;
- regulator-max-microvolt = <1800000>;
- regulator-boot-on;
- };
