Merge tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Olof Johansson: "This is a good healthy set of various code removals. Total net delta is 8100 lines removed. Among the larger cleanups are: - Removal of old Samsung S3C DMA infrastructure by Arnd - Removal of the non-DT version of the 'lager' board by Magnus Damm - General stale code removal on OMAP and Davinci by Rickard Strandqvist - Removal of non-DT support on am3517 platforms by Tony Lindgren ... plus several other cleanups of various platforms across the board" * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (47 commits) ARM: sirf: drop redundant function and marco declaration arm: omap: specify PMUs are for ARMv7 CPUs arm: shmobile: specify PMUs are for ARMv7 CPUs arm: iop: specify PMUs are for XScale CPUs arm: pxa: specify PMUs are for XScale CPUs arm: realview: specify PMU types ARM: SAMSUNG: remove unused DMA infrastructure ARM: OMAP3: Add back Kconfig option MACH_OMAP3517EVM for ASoC ARM: davinci: Remove CDCE949 driver ARM: at91: remove useless at91rm9200_set_type() ARM: at91: remove useless at91rm9200_dt_initialize() ARM: at91: move debug-macro.S into the common space ARM: at91: remove useless at91_sysirq_mask_rtx ARM: at91: remove useless config MACH_AT91SAM9_DT ARM: at91: remove useless config MACH_AT91RM9200_DT ARM: at91: remove unused mach/memory.h ARM: at91: remove useless header file includes ARM: at91: remove unneeded header file rtc: at91/Kconfig: remove useless options ARM: at91/Documentation: add a README for Atmel SoCs ...
