| description: | |
| GPIO specifier that controls power to the device. |
| |
| This property should be provided when the device has a dedicated |
| switch that controls power to the device. The supply state is |
| entirely the responsibility of the device driver. |
| |
| Contrast with vin-supply. |

| vin-supply: |
| type: phandle |
| required: false |
| description: | |
| Reference to the regulator that controls power to the device. |
| The referenced devicetree node must have a regulator compatible. |
| |
| This property should be provided when device power is supplied |
| by a shared regulator. The supply state is dependent on the |
| request status of all devices fed by the regulator. |
| |
| Contrast with supply-gpios. If both properties are provided |
| then the regulator must be requested before the supply GPIOS is |
| set to an active state, and the supply GPIOS must be set to an |
| inactive state before releasing the regulator. |
