Why?
The following files are included that the audio driver depends on
Do you understand how emails work and patch review? I commented under
your change, not unrelated code being there already.
Sorry, I will check the rule. Thanks you!
it is same as sm1 chip

Old style was correct.
I didn't understand where you were referring to, I'm guessing that's
what it was about
Read your patch.


the following changes to tdmif_a

old:

clock-names = "mclk", "sclk", "lrclk";

new:
clock-names = "sclk", "lrclk","mclk";
it fix warning
How is this related to the patch hunk?

Do you understand how patch format works?

Why? What is happening in this patch - why are you changing so many
other pieces?
You did not respond here, so I assume you will fix this and do intensive
review before posting next version.

That's not a simple bus in such case.
these code base on old dts like sm1/g12a, we didn't easily change any of
the relevant properties

To be consistent with the previous one
Still NAK.

You cannot add bugs just to be consistent.
