Merge tag 'late-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC late changes from Arnd Bergmann: "These are changes that arrived a little late before the merge window or that have multiple dependencies on previous branches so they did not fit into one of the earlier ones. There are 10 branches merged here, a total of 39 non-merge commits. Contents are a mixed bag for the above reasons: * Two new SoC platforms: ST microelectronics stixxxx and the TI 'Nspire' graphing calculator. These should have been in the 'soc' branch but were a little late * Support for the Exynos 5420 variant in mach-exynos, which is based on the other exynos branches to avoid conflicts. * Various small changes for sh-mobile, ux500 and davinci * Common clk support for MSM" * tag 'late-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (39 commits) ARM: ux500: bail out on alien cpus ARM: davinci: da850: adopt to pinctrl-single change for configuring multiple pins serial: sh-sci: Initialise variables before access in sci_set_termios() ARM: stih41x: Add B2020 board support ARM: stih41x: Add B2000 board support ARM: sti: Add DEBUG_LL console support ARM: sti: Add STiH416 SOC support ARM: sti: Add STiH415 SOC support ARM: msm: Migrate to common clock framework ARM: msm: Make proc_comm clock control into a platform driver ARM: msm: Prepare clk_get() users in mach-msm for clock-pcom driver ARM: msm: Remove clock-7x30.h include file ARM: msm: Remove custom clk_set_{max,min}_rate() API ARM: msm: Remove custom clk_set_flags() API msm: iommu: Use clk_set_rate() instead of clk_set_min_rate() msm: iommu: Convert to clk_prepare/unprepare msm_sdcc: Convert to clk_prepare/unprepare usb: otg: msm: Convert to clk_prepare/unprepare msm_serial: Use devm_clk_get() and properly return errors msm_serial: Convert to clk_prepare/unprepare ...
