1 MAXIM, MAX77686 regulators 2 3 This device uses two drivers: 4 - drivers/power/pmic/max77686.c (as parent I/O device) 5 - drivers/power/regulator/max77686.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/max77686.txt 11 12 Required subnode: 13 - voltage-regulators: required for the PMIC driver 14 15 Required properties: 16 - regulator-name: used for regulator uclass platform data '.name' 17 18 Optional: 19 - regulator-min-microvolt: minimum allowed Voltage to set 20 - regulator-max-microvolt: minimum allowed Voltage to set 21 - regulator-always-on: regulator should be never disabled 22 - regulator-boot-on: regulator should be enabled by the bootloader 23 24 Example: 25 (subnode of max77686 pmic node) 26 voltage-regulators { 27 ldo1 { 28 regulator-name = "VDD_ALIVE_1.0V"; 29 regulator-min-microvolt = <1000000>; 30 regulator-max-microvolt = <1000000>; 31 regulator-always-on; 32 regulator-boot-on; 33 }; 34 35 ldo2 { 36 regulator-name = "VDDQ_VM1M2_1.2V"; 37 regulator-min-microvolt = <1200000>; 38 regulator-max-microvolt = <1200000>; 39 regulator-always-on; 40 regulator-boot-on; 41 }; 42 . 43 . 44 . 45 ldo26 { 46 regulator-name = "nc"; 47 regulator-min-microvolt = <3000000>; 48 regulator-max-microvolt = <3000000>; 49 regulator-always-on; 50 regulator-boot-on; 51 }; 52 53 buck1 { 54 regulator-compatible = "BUCK1"; 55 regulator-name = "VDD_MIF_1.0V"; 56 regulator-min-microvolt = <8500000>; 57 regulator-max-microvolt = <1100000>; 58 regulator-always-on; 59 regulator-boot-on; 60 }; 61 . 62 . 63 . 64 buck9 { 65 regulator-compatible = "BUCK9"; 66 regulator-name = "nc"; 67 regulator-min-microvolt = <1200000>; 68 regulator-max-microvolt = <1200000>; 69 }; 70 }; 71
