Merge tag 'fixes-for-linus2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson: "Here's a long-pending fixes pull request for arm-soc (I didn't send one in the -rc4 cycle). The larger deltas are from: - A fixup of error paths in the mvsdio driver - Header file move for a driver that hadn't been properly converted to multiplatform on i.MX, which was causing build failures when included - Device tree updates for at91 dealing mostly with their new pinctrl setup merged in 3.8 and mistakes in those initial configs The rest are the normal mix of small fixes all over the place; sunxi, omap, imx, mvebu, etc, etc." * tag 'fixes-for-linus2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (40 commits) mfd: vexpress-sysreg: Don't skip initialization on probe ARM: vexpress: Enable A7 cores in V2P-CA15_A7's Device Tree ARM: vexpress: extend the MPIDR range used for pen release check ARM: at91/dts: correct comment in at91sam9x5.dtsi for mii ARM: at91/at91_dt_defconfig: add at91sam9n12 SoC to DT defconfig ARM: at91/at91_dt_defconfig: remove memory specification to cmdline ARM: at91/dts: add macb mii pinctrl config for kizbox ARM: at91: rm9200: remake the BGA as default version ARM: at91: fix gpios on i2c-gpio for RM9200 DT ARM: at91/at91sam9x5 DTS: add SCK USART pins ARM: at91/at91sam9x5 DTS: correct wrong PIO BANK values on u(s)arts ARM: at91/at91-pinctrl documentation: fix typo and add some details ARM: kirkwood: fix missing #interrupt-cells property mmc: mvsdio: use devm_ API to simplify/correct error paths. clk: mvebu/clk-cpu.c: fix memory leakage ARM: OMAP2+: omap4-panda: add UART2 muxing for WiLink shared transport ARM: OMAP2+: DT node Timer iteration fix ARM: OMAP2+: Fix section warning for omap_init_ocp2scp() ARM: OMAP2+: fix build break for omapdrm ARM: OMAP2: Fix missing omap2xxx_clkt_vps_late_init function calls ...
