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