title: Krait Processor Sub-system (KPSS) Application Clock Controller (ACC) v1
maintainers:
- Christian Marangi <ansuelsmth@gmail.com>
description:
The KPSS ACC provides clock, power domain, and reset control to a Krait CPU.
There is one ACC register region per CPU within the KPSS remapped region as
well as an alias register region that remaps accesses to the ACC associated
with the CPU accessing the region. ACC v1 is currently used as a
clock-controller for enabling the cpu and handling the aux clocks.
