    mmc: s3cmci: Use the slot GPIO descriptor · d2951dfa
    Linus Walleij authored
    Simplify things by making the S3CMCI driver just use
    slot GPIO with descriptors instead of passing around the
    global GPIO numbers that we want to get rid of.
    
    Getting the names of the GPIO chips into the machine
    descriptor tables was a bit of a challenge but I think
    I have them right.
    
    The platform data supports passing in inversion flags, but
    no platform is using them, and it is highly unlikely
    that we will add more, so drop them. The long term plan
    is to let the inversion flags on the GPIO machine
    descriptor do the job.
    
    The lines are flagged as GPIO_ACTIVE_[LOW|HIGH] as that is
    what they are, and since we can now rely on the descriptors
    to have the right polarity, we set the
    "override_active_level" to false in mmc_gpiod_request_cd()
    and mmc_gpiod_request_ro().
