Merge tag 'drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull "ARM: driver specific updates" from Arnd Bergmann: "These are all specific to some driver. They are typically the platform side of a change in the drivers directory, such as adding a new driver or extending the interface to the platform. In cases where there is no maintainer for the driver, or the maintainer prefers to have the platform changes in the same branch as the driver changes, the patches to the drivers are included as well. A much smaller set of driver updates that depend on other branches getting merged first will be sent later. The new export of tegra_chip_uid conflicts with other changes in fuse.c. In rtc-sa1100.c, the global removal of IRQF_DISABLED conflicts with the cleanup of the interrupt handling of that driver. Signed-off-by: Arnd Bergmann <arnd@arndb.de>" Fixed up aforementioned trivial conflicts. * tag 'drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (94 commits) ARM: SAMSUNG: change the name from s3c-sdhci to exynos4-sdhci mmc: sdhci-s3c: add platform data for the second capability ARM: SAMSUNG: support the second capability for samsung-soc ARM: EXYNOS: add support DMA for EXYNOS4X12 SoC ARM: EXYNOS: Add apb_pclk clkdev entry for mdma1 ARM: EXYNOS: Enable MDMA driver regulator: Remove bq24022 regulator driver rtc: sa1100: add OF support pxa: magician/hx4700: Convert to gpio-regulator from bq24022 ARM: OMAP3+: SmartReflex: fix error handling ARM: OMAP3+: SmartReflex: fix the use of debugfs_create_* API ARM: OMAP3+: SmartReflex: micro-optimization for sanity check ARM: OMAP3+: SmartReflex: misc cleanups ARM: OMAP3+: SmartReflex: move late_initcall() closer to its argument ARM: OMAP3+: SmartReflex: add missing platform_set_drvdata() ARM: OMAP3+: hwmod: add SmartReflex IRQs ARM: OMAP3+: SmartReflex: clear ERRCONFIG_VPBOUNDINTST only on a need ARM: OMAP3+: SmartReflex: Fix status masking in ERRCONFIG register ARM: OMAP3+: SmartReflex: Add a shutdown hook ARM: OMAP3+: SmartReflex Class3: disable errorgen before disable VP ...
