    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.
