| Fixed Voltage regulator |
| |
| Binding: |
| The binding is done by the property "compatible" - this is different, than for |
| binding by the node prefix (doc/device-tree-bindings/regulator/regulator.txt). |
| |
| Required properties: |
| - compatible: "regulator-fixed" |
| - regulator-name: this is required by the regulator uclass |
| |
| Optional properties: |
| - gpio: GPIO to use for enable control |
| - startup-delay-us: startup time in microseconds |
| - u-boot,off-on-delay-us: off delay time in microseconds |
| - regulator constraints (binding info: regulator.txt) |
| - enable-active-high: Polarity of GPIO is Active high. If this property |
| is missing, the default assumed is Active low. |
| |
| |
| Other kernel-style properties, are currently not used. |
| |
| Note: |
| For the regulator constraints, driver expects that: |
| - regulator-min-microvolt is equal to regulator-max-microvolt |
| - regulator-min-microamp is equal to regulator-max-microamp |
| |
| Example: |
| fixed_regulator@0 { |
| /* Mandatory */ |
| compatible = "regulator-fixed"; |
| regulator-name = "LED_3.3V"; |
| |
| /* Optional: */ |
| gpio = <&gpc1 0 GPIO_ACTIVE_LOW>; |
| |
| /* Optional for regulator uclass */ |
| regulator-min-microvolt = <3300000>; |
| regulator-max-microvolt = <3300000>; |
| regulator-min-microamp = <15000>; |
| regulator-max-microamp = <15000>; |
| regulator-always-on; |
| regulator-boot-on; |
| enable-active-high; |
| }; |
