Merge tag 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Arnd Bergmann: "These bug fixes are for the largest part for mvebu/kirkwood, which saw a few regressions after the clock infrastructure was enabled, and for OMAP, which showed a few more preexisting bugs with the new multiplatform support. Other small fixes are for imx, mxs, tegra, spear and socfpga" * tag 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (37 commits) ARM: spear3xx: Use correct pl080 header file Arm: socfpga: pl330: Add #dma-cells for generic dma binding support ARM: multiplatform: Sort the max gpio numbers. ARM: imx: fix typo "DEBUG_IMX50_IMX53_UART" ARM: imx: pll1_sys should be an initial on clk arm: mach-orion5x: fix typo in compatible string of a .dts file arm: mvebu: fix address-cells in mpic DT node arm: plat-orion: fix address decoding when > 4GB is used arm: mvebu: Reduce reg-io-width with UARTs ARM: Dove: add RTC device node arm: mvebu: enable the USB ports on Armada 370 Reference Design board ARM: dove: drop "select COMMON_CLK_DOVE" rtc: rtc-mv: Add support for clk to avoid lockups gpio: mvebu: Add clk support to prevent lockup ARM: kirkwood: fix to retain gbe MAC addresses for DT kernels ARM: kirkwood: of_serial: fix clock gating by removing clock-frequency ARM: mxs: cfa10049: Fix fb initialisation function ARM: SPEAr13xx: Fix typo "ARCH_HAVE_CPUFREQ" ARM: OMAP: RX-51: add missing USB phy binding clk: Tegra: Remove duplicate smp_twd clock ...
