    Hmm, I do not think it fits right away, as I do not think it's sensible
    to have pinctrl client drivers call pin_config_set() directly.

    Since the ARM community is the one who is most interested in pinctrl
    subsystem so far, I guess copying LAKML will help collect more comments
    and various tags. (For example, I'm interested in pinctrl, but I do
    not track LKML as close as I do for LAKML).

    That's something we are waiting for pinconf being usable for imx.
