description: |
  The ACC (Alphascale Clock Controller) is responsible for choosing proper
  clock source, setting dividers and clock gates.

  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.
