Subject: [RFC PATCH v3 5/6] clk: meson: a1: add the audio clock controller driver
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.
