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

10- compatible:
11	Usage: required
12	Value type: <string>
13	Definition: should be one of:
14			"qcom,kpss-acc-v1"
15			"qcom,kpss-acc-v2"
16
17- reg:
18	Usage: required
19	Value type: <prop-encoded-array>
20	Definition: the first element specifies the base address and size of
21		    the register region. An optional second element specifies
22		    the base address and size of the alias register region.
23
24- clocks:
25        Usage: required
26        Value type: <prop-encoded-array>
27        Definition: reference to the pll parents.
28
29- clock-names:
30        Usage: required
31        Value type: <stringlist>
32        Definition: must be "pll8_vote", "pxo".
33
34- clock-output-names:
35	Usage: optional
36	Value type: <string>
37	Definition: Name of the output clock. Typically acpuX_aux where X is a
38		    CPU number starting at 0.
