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- startup-delay-us: startup time in microseconds 14- regulator constraints (binding info: regulator.txt) 15 16Other kernel-style properties, are currently not used. 17 18Note: 19For the regulator constraints, driver expects that: 20- regulator-min-microvolt is equal to regulator-max-microvolt 21- regulator-min-microamp is equal to regulator-max-microamp 22 23Example: 24fixed_regulator@0 { 25 /* Mandatory */ 26 compatible = "regulator-fixed"; 27 regulator-name = "LED_3.3V"; 28 29 /* Optional: */ 30 gpio = <&gpc1 0 GPIO_ACTIVE_LOW>; 31 32 /* Optional for regulator uclass */ 33 regulator-min-microvolt = <3300000>; 34 regulator-max-microvolt = <3300000>; 35 regulator-min-microamp = <15000>; 36 regulator-max-microamp = <15000>; 37 regulator-always-on; 38 regulator-boot-on; 39}; 40
