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"
