Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson: "We didn't have any fixes sent up for -rc2, so this is a slightly larger batch. A bit all over the place platform-wise; OMAP, at91, marvell, renesas, sunxi, ux500, etc. I tried to summarize highlights but there isn't a whole lot to point out. Lots of little things fixed all over. A couple of defconfig updates due to new/changing options." * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (44 commits) ARM: at91/sama5: fix incorrect PMC pcr div definition ARM: at91/dt: fix macb pinctrl_macb_rmii_mii_alt definition ARM: at91: at91sam9n12: move external irq declatation to DT ARM: shmobile: marzen: Use error values in usb_power_* ARM: tegra: defconfig fixes ARM: nomadik: fix IRQ assignment for SMC ethernet ARM: vt8500: Add missing NULL terminator in dt_compat clk: tegra: add ac97 controller clock clk: tegra: remove USB from clk init table ARM: dts: mvebu: Fix wrong the address reg value for the L2-cache node ARM: plat-orion: Fix num_resources and id for ge10 and ge11 ARM: OMAP2+: hwmod: Remove sysc slave idle and auto idle apis SERIAL: OMAP: Remove the slave idle handling from the driver ARM: OMAP2+: serial: Remove the un-used slave idle hooks ARM: OMAP2+: hwmod-data: UART IP needs software control to manage sidle modes ARM: OMAP2+: hwmod: Add a new flag to handle SIDLE in SWSUP only in active ARM: OMAP2+: hwmod: Fix sidle programming in _enable_sysc()/_idle_sysc() arm: mvebu: fix the 'ranges' property to handle PCIe ARM: mvebu: select ARCH_REQUIRE_GPIOLIB for mvebu platform ARM: AM33XX: Add missing .clkdm_name to clkdiv32k_ick clock ...
