7title: Socionext UniPhier peripheral core reset in glue layer
8
9description: |
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.
