    use-gta02-glamo-mci-sd-dynamic-clock.patch
    
    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.

    add-glamo-mci-slower-clocking-dynamic-switching.patch
    
    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:
    
    glamo_mci.sd_slow_ratio=8
    
    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.

    fix-allow-full-sd-voltage-range-selection.patch
    
    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.
