Merge tag 'for-3.8-at91_header_clean' of git://github.com/at91linux/linux-at91 into next/headers
From Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>:
arm: at91: mach header cleanup
This first patch serie start the cleanup of the header in mach
by moving all the platform data to include/linux/platform_data
and move the board header and drivers header next to them

arm: at91: move reset controller header to arm/arm/mach-at91
arm: at91: move pit define to the driver
arm: at91: move at91_shdwc.h to arch/arm/mach-at91
arm: at91: move board header to arch/arm/mach-at91
