commit d4b28ec4e2818207cc0e48b90dbce581e0b779e7

    This patch uses the new glamo-mci slow clock ratio
    patch in order to dynamically reduce SD Card clock
    rate when the GPS unit is powered on GTA02.

commit 6d8e14dc4253f3921aff1bbbeb3caf073aa6a7b2
Author: Andy Green <andy at>

    This patch gives glamo-mci a concept of a platform-defined
    dynamic clock slowing callback.  It means that platform code
    can associate some completely external state to decide if
    we run the SD clock at normal rate or a rate divided by a
    module parameter "sd_slow_ratio", which you can set on
    kernel commandline like this:
    you can also change it at runtime by
    echo 8 > /sys/module/glamo_mci/parameters/sd_slow_ratio
    If no platform callback is defined, then no slow mode
    is used.  If it is defined, then the default division
    action is / 8, eg, 16MHz normal -> 2MHz slow mode.

commit 00e20ff234e6d35a6df7e86c043fdda7da06bf04

    Until now we just drove the SD Card at 3.3V all the time.  But in
    fact we can do better, and use a voltage negotiated with the
    SD Card itself.
    With the shipping 512MB Sandisk SD Card, 2.7V is negotiated which
    gives 1.7dBm reduction in power on all the SD Card lines and should
    further reduce GPS perturbation during SD Card usage.
