    fix-force-backlight-down-on-glamo-suspend.patch
    
    There's a bit of a flash when glamo goes into suspend
    but LCM is still seeing white pixels.  This kills the
    backlight before we stop producing meaningful video.

    fix-backlight-disable-on-zero-intensity.patch
    
    It's never right to put 0 intensity into LEDOUT according to datasheet
    But having a floor at intensity 2 means backlight isn't properly off
    when "dimmed".  So change to intensity 0 --> disable backlight.

    add-force-backlight-up-on-resume.patch
    
    The backlight status is restored during resume action, if it was
    off then it resumes like that.
    
    This patch forces it on after resume.

commit 24670fc14b787b45bc8a687419a52f6d32ab4923

    fix-suspend-backlight-timing-pm-debug.patch
    
    This patch improves the smoothness of suspend and resume action.
    
    Taking out CONFIG_PM_DEBUG allows much more rapid resume (the low level
    serial traffic appears to be synchronous)
    
    Added a platform callback in jbt driver and support in pcf50633 so we
    can defer bringing up the backlight until the LCM is able to process
    video again (which must happen after the glamo is up and producing
    video beacuse the LCM is hooked to glamo SPI)
    
    GTA01 should not be affected by all this as the callback will default
    to null and it is on pcf50606

    config-add-back-MMC_UNSAFE_RESUME.patch
    
    It seems thanks to a patch by David Woodhouse unsafe resume
    is working OK for SD rootfs now :-)))))
