Merge tag 'fixes-for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull arm-soc fixes from Arnd Bergmann: "Bug fixes for a number of ARM platforms, mostly OMAP, imx and at91. These come a little later than I had hoped but unfortunately we had a few of these patches cause regressions themselves and had to work out how to deal with those in the meantime." * tag 'fixes-for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (38 commits) Revert "ARM i.MX25: Fix PWM per clock lookups" ARM: versatile: fix versatile_defconfig ARM: mvebu: update defconfig with 3.7 changes ARM: at91: fix at91x40 build ARM: socfpga: Fix socfpga compilation with early_printk() enabled ARM: SPEAr: Remove unused empty files MAINTAINERS: Add arm-soc tree entry ARM: dts: mxs: add the "clock-names" for gpmi-nand ARM: ux500: Correct SDI5 address and add some format changes ARM: ux500: Specify AMBA Primecell IDs for Nomadik I2C in DT ARM: ux500: Fix build error relating to IRQCHIP_SKIP_SET_WAKE ARM: at91: drop duplicated config SOC_AT91SAM9 entry ARM: at91/i2c: change id to let i2c-at91 work ARM: at91/i2c: change id to let i2c-gpio work ARM: at91/dts: at91sam9g20ek_common: Fix typos in buttons labels.
