| Fixed Voltage regulators |
| |
| Required properties: |
| - compatible: Must be "regulator-fixed"; |
| - regulator-name: Defined in regulator.txt as optional, but required here. |
| |
| 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>; |
| }; |
