Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
arm-soc fixes for 3.3-rc: AT91 needed reset fixes which resulted in some minor code refactoring, it also adds a feature-removal for one of their platforms for 3.4. The USB patches have been acked by Greg K-H. i.MX and ux500 both have some minor fixes, nothing controversial. * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: arch/arm/mach-imx/mach-mx53_ard.c: add missing iounmap ARM: imx: iomux-v1.h: Fix build error due to __init annotation ARM: at91: Fix at91sam9g45 and at91cap9 reset ARM: at91: make rstc soc independent ARM: at91: introduce AT91_SAM9_ALT_RESET to select the at91sam9 alternative reset ARM: at91: merge at91cap9_ddrsdr.h in at91sam9_ddrsdr.h ARM: at91: fix cap9 ddrsdr register ARM/USB: at91/ohci-at91: rename vbus_pin_inverted to vbus_pin_active_low USB: at91: fix clk_get error handling ARM: at91: removal of CAP9 SoC family ARM: at91: fix at91rm9200 soc subtype handling mach-ux500: no MMC_CAP_SD_HIGHSPEED on Snowball mach-ux500: enable ARM errata 764369 mach-ux500: do not override outer.inv_all mach-ux500: musb: now musb is always in OTG mode ARM: imx6: add missing twd_clk for imx6q clock
