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