+title: Cortex-A7 Processor Sub-system (CPSS) Application Clock Controller (ACC)

+description: |
+  The CPSS ACC provides clock, power domain, and reset control to a Cortex-A7
+  processor. There is one ACC register region per CPU within the PSS remapped
+  region as well as an alias register region that remaps accesses to the ACC
+  associated with the CPU accessing the region.
