1Sandbox, PMIC regulators 2 3This device uses two drivers: 4- drivers/power/pmic/sandbox.c (as parent I/O device) 5- drivers/power/regulator/sandbox.c (for child regulators) 6 7This file describes the binding info for the REGULATOR driver. 8 9First, please read the binding info for the PMIC: 10- doc/device-tree-bindings/pmic/sandbox.txt 11 12Required subnodes: 13- ldoN { }; 14- buckN { }; 15 16The sandbox PMIC can support: ldo1, ldo2, buck1, buck2. 17 18For each PMIC's regulator subnode, there is one required property: 19- regulator-name: used for regulator uclass platform data '.name' 20 21Optional: 22- regulator-min-microvolt: minimum allowed Voltage to set 23- regulator-max-microvolt: minimum allowed Voltage to set 24- regulator-min-microamps: minimum allowed Current limit to set (LDO1/BUCK1) 25- regulator-max-microamps: minimum allowed Current limit to set (LDO1/BUCK1) 26- regulator-always-on: regulator should be never disabled 27- regulator-boot-on: regulator should be enabled by the bootloader 28 29Example PMIC's regulator subnodes: 30 31ldo1 { 32 regulator-name = "VDD_1.0V"; 33 regulator-min-microvolt = <1000000>; 34 regulator-max-microvolt = <1200000>; 35 regulator-min-microamps = <100000>; 36 regulator-max-microamps = <400000>; 37 regulator-always-on; 38}; 39 40buck2 { 41 regulator-name = "VDD_1.8V"; 42 regulator-min-microvolt = <1800000>; 43 regulator-max-microvolt = <1800000>; 44 regulator-boot-on; 45}; 46
