Merge branch 'ep93xx-for-arm-soc' of git://github.com/RyanMallon/linux-2.6 into next/cleanup
* 'ep93xx-for-arm-soc' of git://github.com/RyanMallon/linux-2.6:
ep93xx: Remove unnecessary includes of ep93xx-regs.h
ep93xx: Move EP93XX_SYSCON defines to SoC private header
ep93xx: Move crunch code to mach-ep93xx directory
ep93xx: Make syscon access functions private to SoC
ep93xx: Configure GPIO ports in core code
ep93xx: Move peripheral defines to local SoC header
ep93xx: Convert the watchdog driver into a platform device.
ep93xx: Use ioremap for backlight driver
ep93xx: Move GPIO defines to gpio-ep93xx.h
ep93xx: Don't use system controller defines in audio drivers
ep93xx: Move PHYS_BASE defines to local SoC header file
(update to v3.3-rc7)
