| 7 | title: Socionext UniPhier peripheral core reset in glue layer |
| 8 | |
| 9 | description: | |
| 10 | Some peripheral core reset belongs to its own glue layer. Before using |
| 11 | this core reset, it is necessary to control the clocks and resets to |
| 12 | enable this layer. These clocks and resets should be described in each |
| 13 | property. |
