Add argument. BUT checking more carefully, the chip does have audio top clocks, one for each controller, plus a common one. Check EE_AUDIO2_CLK81_EN and EE_AUDIO2_GATE_EN0. There is a tree to properly implement, same as sm1. * EE_AUDIO2_CLK81_CTRL (which you skipped) feeds EE_AUDIO2_CLK81_EN * EE_AUDIO2_CLK81_EN should be the parent of audio_top * audio_top the parent of pclks - VAD is pclks are skipping it, is intentional ?

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.
