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