      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.
