1Alphascale Clock Controller
2
3The ACC (Alphascale Clock Controller) is responsible of choising proper
4clock source, setting deviders and clock gates.
5
6Required properties for the ACC node:
7 - compatible: must be "alphascale,asm9260-clock-controller"
8 - reg: must contain the ACC register base and size
9 - #clock-cells : shall be set to 1.
10
11Simple one-cell clock specifier format is used, where the only cell is used
12as an index of the clock inside the provider.
13It is encouraged to use dt-binding for clock index definitions. SoC specific
14dt-binding should be included to the device tree descriptor. For example
15Alphascale ASM9260:
16#include <dt-bindings/clock/alphascale,asm9260.h>
17
18This binding contains two types of clock providers:
19 _AHB_ - AHB gate;
20 _SYS_ - adjustable clock source. Not all peripheral have _SYS_ clock provider.
21All clock specific details can be found in the SoC documentation.
