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: "A bunch of fixes for regressions (and a few other problems) in 3.4-rc1: - Fix for regression of mach/io.h cleanup on platforms with PCI or PCMCIA (adding back the include file on those for now) - AT91 fixes for usb and spi - smsc911x ethernet fixes for i.MX - smsc911x fixes for OMAP - gpio fixes for Tegra - A handful of build error and warning fixes for various platforms - cpufreq kconfig dependencies, build and lowlevel debug fixes for Samsung platforms In other words, more or less the regular collection of -rc1/2 type material. A few of them, in particular the smsc911x for OMAP series, aren't technically regressions for 3.4, but they're valid fixes and we're still relatively early in the rc cycle so it seems appropriate to include them." * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (60 commits) ARM: fix __io macro for PCMCIA ARM: EXYNOS: Fix compiler warning in dma.c file ARM: EXYNOS: fix ISO C90 warning ARM: OMAP2+: hwmod: Fix wrong SYSC_TYPE1_XXX_MASK bit definitions ARM: OMAP2+: hwmod: Make omap_hwmod_softreset wait for reset status ARM: OMAP2+: hwmod: Restore sysc after a reset ARM: OMAP2+: omap_hwmod: Allow io_ring wakeup configuration for all modules ARM: OMAP3: clock data: fill in some missing clockdomains ARM: OMAP4: clock data: Force a DPLL clkdm/pwrdm ON before a relock ARM: OMAP4: clock data: fix mult and div mask for USB_DPLL ARM: OMAP2+: powerdomain: Wait for powerdomain transition in pwrdm_state_switch() gpio: tegra: Iterate over the correct number of banks gpio: tegra: fix register address calculations for Tegra30 EXYNOS: fix dependency for EXYNOS_CPUFREQ ARM: at91: dt: remove unit-address part for memory nodes ARM: at91: fix check of valid GPIO for SPI and USB USB: ehci-atmel: add needed of.h header file ARM: at91/NAND DT bindings: add comments ARM: at91/at91sam9x5.dtsi: fix NAND ale/cle in DT file USB: ohci-at91: trivial return code name change ...
