Probably. But the question is still why this should be changed in
U-Boot. Why doesn't the Linux driver set the pin mux configuration
it needs?
Sorry, I don't know. The Linux driver developers told me "there is no
U-Boot dependency". Maybe they could answer this question? CCed.
The kernel has a pinctrl driver for i.MX 6, so I would rather suggest
to fix your imx6q-sabrelite.dts Device Tree source file so that the
audio device is properly associated with the correct pinmux
configuration.
I'm using
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=b7879fe6dad97ce08e8df0bf8d408942c436d358
Each device can have a pinctrl-0 DT property, which points to one or
more pinmux configurations that are defined in imx6q.dtsi file. You can
add additional pinmux configurations here if needed.
Sounds like the above is incomplete, then?
But yeah, definitely, the kernel shouldn't rely too much on U-Boot
having set the right pinmux configuration.
Best regards
Dirk
