9354d7675SEmmanuel Vadotdescription: |
10354d7675SEmmanuel Vadot  Some peripheral core reset belongs to its own glue layer. Before using
11354d7675SEmmanuel Vadot  this core reset, it is necessary to control the clocks and resets to
12354d7675SEmmanuel Vadot  enable this layer. These clocks and resets should be described in each
13354d7675SEmmanuel Vadot  property.
