| Regulator nodes should be named to DSVP and DSVN. The |
| definition for each of these nodes is defined using the standard |
| binding for regulators at |
| Documentation/devicetree/bindings/regulator/regulator.txt. |

| description: GPIOs to use to enable DSVP/DSVN regulator. |
| The first one is ENP to enable DSVP, and second one is ENM to enable DSVN. |
| Number of GPIO in the array list could be 1 or 2. |
| If only one gpio is specified, only one gpio used to control ENP/ENM. |
| Else if both are specified, DSVP/DSVN could be controlled individually. |
| If this property not specified, treat both as always-on regulators. |
| |
| Property is deprecated. Use enable-gpios in each regulator. |
