What I noticed some time ago on N810 but not time to fix it that OMAP mux change dropped muxing audio McBSP pins. Those pins are muxed by reset or bootloader to another function.
Probably a few lines to arch/arm/boot/dts/omap2420-n810.dts etc.
Hmm do you have a link or commit id to a patch that does the muxing to see which pins need to be muxed?
Could it have been as old as 5a87cde490e1 ("ARM: OMAP2+: Remove legacy booting support for n8x0")? At least it is dropping the McBSP muxing from board-n8x0.c.
Yup OK makes sense. I probably thought it's safe to do as I recall the Nokia kernels doing all the muxing in the bootloader. But seems I was wrong, sorry about that.
