Linus Torvalds 6c5096e553 arm-soc: board specific changes 
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
 
 Conflicts include the omap board-apollon.c file that is removed without
 a replacement, and conflicting context in the 4430sdp board file.
