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.
