From: Linus Torvalds Date: Fri, 6 Sep 2013 20:21:16 +0000 (-0700) Subject: Merge tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm... X-Git-Tag: firefly_0821_release~176^2~5405 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=8e73e367f7dc50f1d1bc22a63e5764bb4eea9b48;p=firefly-linux-kernel-4.4.55.git Merge tag 'cleanup-for-linus' of git://git./linux/kernel/git/arm/arm-soc Pull ARM SoC cleanups from Olof Johansson: "This branch contains code cleanups, moves and removals for 3.12. There's a large number of various cleanups, and a nice net removal of 13500 lines of code. Highlights worth mentioning are: - A series of patches from Stephen Boyd removing the ARM local timer API. - Move of Qualcomm MSM IOMMU code to drivers/iommu. - Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM driver and switching over to the drivers/pwm one. - Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM). There's also a move of a header file out of include/linux/i2c/ to platform_data, where it really belongs. It touches mostly ARM platform code for include changes so we took it through our tree" * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (83 commits) ARM:
