Merge tag 'boards' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC board specific changes from Arnd Bergmann:
"These updates are all for board specific code, including
- defconfig updates for shmobile, davinci, bcm2835, imx, omap and
tegra
- SD/MMC and I2C support on bcm2835 (Raspberry PI)
- minor updates for PXA
- shmobile updates to GPIO usage in board files
- More things in OMAP board files are moved over to device tree
probing
- Better support for audio devices on some OMAP platforms"
