    I have a little confusion. In ARM SoC, a lot of pins are used as
    multi-functions.

    Before suspend, it may be configured as some function that isn't GPIO.
    Is it a goal
    that avoid declaring gpio_request() for suspend and updating the setting of pin?

    Linus,
    Are these two patches are post in mailing list? I can't find your
    second patch in this
    patch series?
