1 Sandbox, PMIC regulators 2 3 This 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 7 This file describes the binding info for the REGULATOR driver. 8 9 First, please read the binding info for the PMIC: 10 - doc/device-tree-bindings/pmic/sandbox.txt 11 12 Required subnodes: 13 - ldoN { }; 14 - buckN { }; 15 16 The sandbox PMIC can support: ldo1, ldo2, buck1, buck2. 17 18 For each PMIC's regulator subnode, there is one required property: 19 - regulator-name: used for regulator uclass platform data '.name' 20 21 Optional: 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 29 Example PMIC's regulator subnodes: 30 31 ldo1 { 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 40 buck2 { 41 regulator-name = "VDD_1.8V"; 42 regulator-min-microvolt = <1800000>; 43 regulator-max-microvolt = <1800000>; 44 regulator-boot-on; 45 }; 46
