Related to my comment in patch 1/6, "mclk" should be defined in the codec
device node. I know that you probably used as a reference Tushar's patch
[0] I posted recently but I just figured out that his dependency patch [1]
mentioned in [2] handled the master clock in the ASoC machine driver but
the final version merged handled it in the codec drivers.

I asked Kukjin to drop the patch to Snow and Peach Pit/Pi and will post
a correct version as a part of a series once I've sound working.

The mic and headphone jack detection are still not supported in the Snow
ASoC machine driver so this pinctrl are not needed but I guess it doesn't
hurt to have them mux'ed too.

Best regards,
Javier
