Comment 14 for bug 420447

I'm attaching two patches to give you what we have of the audio port.
These patches apply cleanly to your fsl-imx51 branch.
Playback and record work.

There is an issue with your regulator stuff that breaks things somewhat.
You will see a boot error that occurs when imx-3stack-sgtl5000.c calls regulator_get. That's
something that needs to get fixed in your regulator stuff. Audio functionality will be broken until this is fixed as the audio does not completely initialize.

There is another issue with a loud pop happening when boot up occurs.
This is because the 'Line In Jack' widget is on all the time. I'm
working on fixing this. As is, audio works, but will never completely
power down, so it becomes an issue with power consumption also.
