Nano pi neo audio support

[Ravikumar]

Hi,

I am working on H3 based Nano Pi Neo board.

my task is to enable audio and kernel version is 4.4.

 

I tested Armbian image, Audio is working fine(good) and capture working too.

Enabled sun4i-codec.c (which has h3 support). I struck with major problem.

I am unable to write AC registors(physical address: 1c22c00) but i can read them using readl. writel is not showing any effect on register.

 

I enabled audio_pll, codec clock, bus codec gate registers and reset deasserted.

 

I have cross-checked H3 datasheet for clock tree. Everything looks fine.

 

why writel is not working?? any suggestion.??

help me.

 

Thanks in advance.
