Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Arnd Bergmann: "A few patches have come up since the merge window. The largest one is a rewrite of the PXA lubbock/mainstone IRQ handling. This was already broken in 2011 by a change to the GPIO code and only noticed now. The other changes contained here are: MAINTAINERS file updates: - Ray Jui and Scott Branden are now co-maintainers for some of the mach-bcm chips, while Christian Daudt and Marc Carino have stepped down. - Andrew Victor is no longer maintaining at91. Instead, Alexandre Belloni now becomes an official maintainer, after having done a bulk of the work for a while. - Baruch Siach, who added the mach-digicolor platform in 4.1 is now listed as maintainer - The git URL for mach-socfpga has changed Bug fixes: - Three bug fixes for new rockchip rk3288 code - A regression fix to make SD card support work on certain ux500 boards - multiple smaller dts fixes for imx, omap, mvebu, and shmobile - a regression fiix for omap3 power consumption - a fix for regression in the ARM CCI bus driver Configuration changes: - more imx platforms are now enabled in multi_v7_defconfig" * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (39 commits) MAINTAINERS: add Conexant Digicolor machines entry MAINTAINERS: socfpga: update the git repo for SoCFPGA ARM: multi_v7_defconfig: Select more FSL SoCs MAINTAINERS: replace an AT91 maintainer drivers: CCI: fix used_mask init in validate_group() bus: omap_l3_noc: Fix master id address decoding for OMAP5 bus: omap_l3_noc: Fix offset for DRA7 CLK1_HOST_CLK1_2 instance ARM: dts: dra7: Fix efuse register size for ABB ARM: dts: am57xx-beagle-x15: Switch GPIO fan number ARM: dts: am57xx-beagle-x15: Switch UART mux pins ARM: dts: am437x-sk: reduce col-scan-delay-us ARM: dts: am437x-sk: fix for new newhaven display module revision ARM: dts: am57xx-beagle-x15: Fix RTC aliases ARM: dts: am57xx-beagle-x15: Fix IRQ type for mcp7941x ARM: dts: omap3: Add #iommu-cells to isp and iva iommu ARM: omap2plus_defconfig: Enable EXTCON_USB_GPIO ARM: dts: OMAP3-N900: Add microphone bias voltages ARM: OMAP2+: Fix omap off idle power consumption creeping up MAINTAINERS: Update brcmstb entry MAINTAINERS: Remove Christian Daudt for mach-bcm ...
