This patch adds fixes for the following issues in Kabylake machine driver
- crackling noise in rt5663 headset codec
And the fix was..?
- enabling 4 slot IV feedback for max98927 speaker amp codec
should that be a separate patch?
- pop noise while recording from rt5514 dmic codec
and this fix was..
Harsha, from the changelog, apart from 2, I am still not clear on the contents of the patch. A patch changelog should document the code changes done, its impact (done here) to help reviewer understand the patch

So now the clock source is ARSC right, how will that fix something?

now you no longer need to set pll?
