Ok, I am talking about using I2Sv5 with Jassi.
Also, Should I specially send this patch to review to Liam?
or What is another way to review?

I see that your mentioned patcth.
before I had received the patch to keep audio path on suspend,
to execute voice-call on suspend implemented that the state of LDO of 
codec is kept high to run audio in cases voice call while the Linux system
is suspended.

I will try to find your mentioned patch and check to apply the sound driver
of Aquila board.

Thank you,
