1Fixed Voltage regulator 2 3Binding: 4The binding is done by the property "compatible" - this is different, than for 5binding by the node prefix (doc/device-tree-bindings/regulator/regulator.txt). 6 7Required properties: 8- compatible: "regulator-fixed" 9- regulator-name: this is required by the regulator uclass 10 11Optional properties: 12- gpio: GPIO to use for enable control 13- regulator constraints (binding info: regulator.txt) 14 15Other kernel-style properties, are currently not used. 16 17Note: 18For the regulator constraints, driver expects that: 19- regulator-min-microvolt is equal to regulator-max-microvolt 20- regulator-min-microamp is equal to regulator-max-microamp 21 22Example: 23fixed_regulator@0 { 24 /* Mandatory */ 25 compatible = "regulator-fixed"; 26 regulator-name = "LED_3.3V"; 27 28 /* Optional: */ 29 gpio = <&gpc1 0 GPIO_ACTIVE_LOW>; 30 31 /* Optional for regulator uclass */ 32 regulator-min-microvolt = <3300000>; 33 regulator-max-microvolt = <3300000>; 34 regulator-min-microamp = <15000>; 35 regulator-max-microamp = <15000>; 36 regulator-always-on; 37 regulator-boot-on; 38}; 39
