Merge tag 'at91-cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanup on mach-at91 from Arnd Bergmann: "On Atmel AT91, the conversion to device tree is now considered complete, and all machines that were not already converted in 3.18 are assumed to be unused and dropped by the maintainer. All remaining board files that were written in C are dropped, and the ancient at91x40 sub-platform (based on an MMU-less ARM7) is removed altogether. Cleaning up the last pieces was great fun, so I took the time to do some of the coding myself and removed several hundred code lines that ended up unused after the board files were done. There are still a couple of AT91 specific device drivers that are not converted to DT (CF, USB-OTG) and currently not working, and the platform itself is not "multiplatform"-enabled, but both issues are going to be taken care of in the 3.20 cycle. This is split out from the other cleanups purely based on the size of the branch" * tag 'at91-cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (33 commits) ARM: at91: remove unused board.h file ARM: at91: remove unneeded header files ARM: at91/clocksource: remove !DT PIT initializations ARM: at91: at91rm9200 ST initialization is now DT only ARM: at91: remove old AT91-specific drivers ARM: at91: cleanup initilisation code by removing dead code ARM: at91/Kconfig: select board files automatically ARM: at91: remove unused IRQ function declarations ARM: at91: remove legacy IRQ driver and related code ARM: at91: remove old at91-specific clock driver ARM: at91: remove clock data in at91sam9n12.c and at91sam9x5.c files ARM: at91: remove all !DT related configuration options ARM: at91/trivial: update Kconfig comment to mention SAMA5 ARM: at91: always USE_OF from now on ARM: at91/Kconfig: remove ARCH_AT91RM9200 option for drivers ARM: at91: switch configuration option to SOC_AT91RM9200 ARM: at91: remove at91rm9200 legacy board support ARM: at91: remove at91rm9200 legacy boards files ARM: at91/Kconfig: remove useless fbdev Kconfig options ARM: at91: remove at91sam9261/at91sam9g10 legacy board support ...
