| title: Socionext UniPhier regulator controller |
| |
| description: | |
| This regulator controls VBUS and belongs to USB3 glue layer. Before using |
| the regulator, it is necessary to control the clocks and resets to enable |
| this layer. These clocks and resets should be described in each property. |
