Merging the andy branch into the stable branch

[Holger Freyther]

Hey Andy,

there are currently 17 patches in your branch that aren't in the stable 
branch. I would like to see the backlight changes and my pcf50633 changes in 
the stable branch. This is only leaving the bt timeouts, glamo debug and MMC 
unsafe resume patch.

Do you plan to merge these to the stable branch? May I merge the backlight 
changes and pcf50633 ones?
