| Fixed Voltage regulators | |
| Required properties: | |
| - compatible: Must be "regulator-fixed"; | |
| Optional properties: | |
| - gpio: gpio to use for enable control | |
| - startup-delay-us: startup time in microseconds | |
| - enable-active-high: Polarity of GPIO is Active high | |
| If this property is missing, the default assumed is Active low. | |
| - gpio-open-drain: GPIO is open drain type. | |
| If this property is missing then default assumption is false. | |
| -vin-supply: Input supply name. | |
| Any property defined as part of the core regulator | |
| binding, defined in regulator.txt, can also be used. | |
| However a fixed voltage regulator is expected to have the | |
| regulator-min-microvolt and regulator-max-microvolt | |
| to be the same. | |
| Example: | |
| abc: fixedregulator@0 { | |
| compatible = "regulator-fixed"; | |
| regulator-name = "fixed-supply"; | |
| regulator-min-microvolt = <1800000>; | |
| regulator-max-microvolt = <1800000>; | |
| gpio = <&gpio1 16 0>; | |
| startup-delay-us = <70000>; | |
| enable-active-high; | |
| regulator-boot-on; | |
| gpio-open-drain; | |
| vin-supply = <&parent_reg>; | |
| }; |
