Ok, great. I was not aware of this problem. Glad to know that it also fixes it.

I can send this same change to nitrogen and wandboard.

Yes, it does.

I started to adding audio support to wandboard in the mainline kernel,
then I saw all the code that mx6qsabrelite uses to configure the cko1,
and I preferred not to repeat it again.

It is much simpler to let the bootloader take care of it, as it is a
simple register write.
