1Fixed Voltage regulators 2 3Required properties: 4- compatible: Must be "regulator-fixed"; 5 6Optional properties: 7- gpio: gpio to use for enable control 8- startup-delay-us: startup time in microseconds 9- enable-active-high: Polarity of GPIO is Active high 10If this property is missing, the default assumed is Active low. 11 12Any property defined as part of the core regulator 13binding, defined in regulator.txt, can also be used. 14However a fixed voltage regulator is expected to have the 15regulator-min-microvolt and regulator-max-microvolt 16to be the same. 17 18Example: 19 20 abc: fixedregulator@0 { 21 compatible = "regulator-fixed"; 22 regulator-name = "fixed-supply"; 23 regulator-min-microvolt = <1800000>; 24 regulator-max-microvolt = <1800000>; 25 gpio = <&gpio1 16 0>; 26 startup-delay-us = <70000>; 27 enable-active-high; 28 regulator-boot-on 29 }; 30
