Merge tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform updates from Olof Johansson: "This branch contains part 1 of the platform updates for 3.10. Among the highlights: - Support for the new Atmel Cortex-A5 based platforms (SAMA5D3) - New support for CSR SiRFatlas6 SoCs - A handful of updates for NVidia T114 (a.k.a. Tegra 4) - A bunch of updates for the shmobile platforms - A handful of updates for davinci - A few updates for Qualcomm MSM - Plus a handful of other patches, defconfig updates, etc." * tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (135 commits) ARM: tegra: pm: fix build error w/o PM_SLEEP ARM: davinci: ensure global variables are declared ARM: davinci: sram.c: fix incorrect type in assignment ARM: davinci: da8xx dt: make file local symbols static ARM: davinci: da8xx: add remoteproc support ARM: socfpga: Upgrade clk driver for socfpga to make use of dts clock entries ARM: socfpga: Add clock entries into device tree ARM: socfpga: Enable soft reset ARM: EXYNOS: replace cpumask by the corresponding macro ARM: EXYNOS: handle properly the return values ARM: EXYNOS: factor out the idle states ARM: OMAP4: Enable fix for Cortex-A9 erratas ARM: OMAP2+: Export SoC information to userspace ARM: OMAP2+: SoC name and revision unification ARM: OMAP2+: Move common part of late init into common function ARM: tegra: pm: remove duplicated include from pm.c ARM: davinci: da850: override mmc DT node device name ARM: davinci: da850: add mmc DT entries mmc: davinci_mmc: add DT support ARM: SAMSUNG: check processor type before cache restoration in resume ...
