This controller provides clocks and reset functionality for audio peripherals on Amlogic A1 SoC family. The driver is almost identical to 'axg-audio', however it would be better to keep it separate due to following reasons: - significant amount of bits has another definition. I will bring there a mess of new defines with A1_ suffixes. - registers of this controller are located in two separate regions. It will give a lot of complications for 'axg-audio' to support this.
