    Disable low level debugging, make the s3c24xx PM debug code depend on DEBUG_LL
    
    Hey,
    where are slowly getting into the product state, low level debugging is
    supposed to be turned off there. :)

    Subject: [PATCH] [debug] Disable low level debugging for the product
         Disable low level debugging in the defconfig-gta02 and
         the s3c pm code used printascii which is only available
         with low level debugging, update the Kconfig entry for
         this pm debugging support to depend on low level debugging

    [power] Use the bq27000 battery to provide charging values for apm
        Built the apm emulation for gta02 and say that the gta02 battery
        is supposed to be used for this apm emulation.

commit e43810a1fec85d25a7bc0108251a9f4a29ea9e03

    [pcf50633] Assume that all gta02's have a battery with coulumb counter
        For the gta02 and the bq27000 battery it does not make sense to use the
        ADC to get the current voltage. Under the assumption that all mass
        production gta02's have such batteries it does not make any sense to
        forward this value to APM.

    [pcf50633] Add exported symbol to the header file
        Reading the battery volt using the ADC was an exported symbol
        but not in the header file, add it.

commit 480d77b75928f0d2befabd57cf5b3ac4382ee824
Author: Holger Freyther <ich at tamarin.(none)>
Date:   Sat May 10 09:57:09 2008 +0100

    [pcf50633] Print less debugging messages
        According to the comments in the code we have to read
        INT1 - INT5 in case of any interrupt. So even if we have masked
        out the periodic timer interrupt we were able to see that it
        fired. Only print that we got a SECOND interrupt if we are actually
        interested in the periodic tick. From a brief look at the datasheet there
        is no way to stop the periodic tick.

commit 2ab99d84be2f2d29a10bdce1d93fbaf9f2651528
Author: Holger Freyther <ich at tamarin.(none)>
Date:   Sat May 10 09:57:09 2008 +0100

    Explain why we want SECOND to kick.
        We do not mask the SECOND interrupt to make sure that we get
        a interrupt at the beginning. We use this for the coldplug_done
        initisalisation.
        So pcf->flags and INT1M is out of sync at the beginning but after the
        first SECOND interrupt it will be put into sync.

    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.

    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
