Merge tag 'drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Browse Source 
Pull ARM soc driver specific changes from Olof Johansson:
 - A long-coming conversion of various platforms to a common LED
   infrastructure
 - AT91 is moved over to use the newer MCI driver for MMC
 - Pincontrol conversions for samsung platforms
 - DT bindings for gscaler on samsung
 - i2c driver fixes for tegra, acked by i2c maintainer

Fix up conflicts as per Olof.
