you have a link? Without having seen that patch this can well be a
separate patch. And (also without having seen the patch) I wonder why
the information which gpio to use doesn't come from the device tree but
is supplied by userspace. I thought about expanding mctrl-gpio for that,
but as there are a few conflicting patches to mctrl-gpio out I wanted to
wait until the dust settles.
Best regards
Uwe
