Merge tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Arnd Bergmann: "The remaining cleanups for 3.19 are to a large part result of devicetree conversion nearing completion on two other platforms besides AT91: - Like AT91, Renesas shmobile is in the process to migrate to DT and multiplatform, but using a different approach of doing it one SoC at a time. For 3.19, the r8a7791 platform and associated "Koelsch" board are considered complete and we remove the non-DT non-multiplatform support for this. - The ARM Versatile Express has supported DT and multiplatform for a long time, but we have still kept the legacy board files around, because not all drivers were fully working before. We have finally taken the last step to remove the board files. Other changes in this branch are preparation for the later branches or just unrelated to the more interesting changes: - The dts files for arm64 get moved into per-vendor directories for a clearer structure. - Some dead code removal (zynq, exynos, davinci, imx) - Using pr_*() macros more consistently instead of printk(KERN_*) in some platform code" * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (71 commits) ARM: zynq: Remove secondary_startup() declaration from header ARM: vexpress: Enable regulator framework when MMCI is in use ARM: vexpress: Remove non-DT code ARM: imx: Remove unneeded .map_io initialization ARM: dts: imx6qdl-sabresd: Fix the microphone route ARM: imx: refactor mxc_iomux_mode() ARM: imx: simplify clk_pllv3_prepare() ARM: imx6q: drop unnecessary semicolon ARM: imx: clean up machine mxc_arch_reset_init_dt reset init ARM: dts: imx6qdl-rex: Remove unneeded 'fsl,mode' property ARM: dts: imx6qdl-gw5x: Remove unneeded 'fsl,mode' property ARM: dts: imx6qdl-sabresd: Use IMX6QDL_CLK_CKO define ARM: at91: remove useless init_time for DT-only SoCs ARM: davinci: Remove redundant casts ARM: davinci: Use standard logging styles ARM: shmobile: r8a7779: Spelling/grammar s/entity/identity/, s/map/mapping/ ARM: shmobile: sh7372: Spelling/grammar s/entity map/identity mapping/ ARM: shmobile: sh73a0: Spelling/grammar s/entity map/identity mapping/ ARM: EXYNOS: Remove unused static iomapping ARM: at91: fix build breakage due to legacy board removals ...
