Thanks a lot for the help. So far, I'm not playing with
suspend/resume, so wkup/core split should not be issue (right?).

How does it work with the devices? AFAICT omap4 groups it logically,
but that's just for easy reading, no?

I tried this, but no luck, mux is not initialized correctly, so code
in board-rx51-video fails, and later fbcon crashes.

Any ideas?

Well if you have any wkup mux registers mapped for core mux,
pinctrl-single will complain about offset being out of range
and not set the values. You can see that in dmesg, or at least
with CONFIG_DEBUG_PINCTRL set.

No, there really are two instances of mux registers even on omap3,
but I missed that earlier while reading the docs, and with the legacy
mux framework it does not matter which mux domain it is. But it
matters for pinctrl-single as it ioremaps the ranges separately.

You may have some wkup mux domain offsets in your .dts file, so
pinctrl-single will abort the muxing.

...

This is not a good way of doing muxing, hogging all the pins under
omap3_pmx_core will make it impossible to unload pinctrl-single
as a module, which is not nice for distros and developers.

Further, if some pins need dynamic remuxing, we can't do it in
the device driver for the device. For n900, dynamic remuxing needs
to be done for eMMC at least, see rx51_mmc2_remux().

Also, see the recent patches that Benoit has queued to use the
preprocessor for the .dts files, we should modify the legacy mux
dump hack to output the mux mode defines instead.

Regards,

Tony
