1 Krait Processor Sub-system (KPSS) Application Clock Controller (ACC)
2
3 The KPSS ACC provides clock, power domain, and reset control to a Krait CPU.
4 There is one ACC register region per CPU within the KPSS remapped region as
5 well as an alias register region that remaps accesses to the ACC associated
6 with the CPU accessing the region.
