| 2 | |
| 3 | Binding: |
| 4 | The binding is done by the property "compatible" - this is different, than for |
| 5 | binding by the node prefix (doc/device-tree-bindings/regulator/regulator.txt). |
| 6 | |
| 7 | Required properties: |
| 8 | - compatible: "regulator-fixed" |
| 9 | - regulator-name: this is required by the regulator uclass |
| 10 | |
| 11 | Optional properties: |
| 12 | - gpio: GPIO to use for enable control |
| 13 | - regulator constraints (binding info: regulator.txt) |
| 14 | |
| 15 | Other kernel-style properties, are currently not used. |
| 16 | |
| 17 | Note: |
| 18 | For the regulator constraints, driver expects that: |
| 19 | - regulator-min-microvolt is equal to regulator-max-microvolt |
| 20 | - regulator-min-microamp is equal to regulator-max-microamp |
| 21 | |
| 22 | Example: |
| 23 | fixed_regulator@0 { |
| 24 | /* Mandatory */ |
| 25 | compatible = "regulator-fixed"; |
| 26 | regulator-name = "LED_3.3V"; |
| 27 | |
| 28 | /* Optional: */ |
| 29 | gpio = <&gpc1 0 GPIO_ACTIVE_LOW>; |
| 30 | |
| 31 | /* Optional for regulator uclass */ |
| 32 | regulator-min-microvolt = <3300000>; |
| 33 | regulator-max-microvolt = <3300000>; |
| 34 | regulator-min-microamp = <15000>; |
| 35 | regulator-max-microamp = <15000>; |
| 36 | regulator-always-on; |
| 37 | regulator-boot-on; |
| 38 | }; |
