Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver specific changes from Arnd Bergmann: "These changes are all driver specific and cross over between arm-soc contents and some other subsystem, in these cases cpufreq, crypto, dma, pinctrl, mailbox and usb, and the subsystem owners agreed to have these changes merged through arm-soc. As we proceed to untangle the dependencies between platform code and driver code, the amount of changes in this category is fortunately shrinking, for 3.11 we have 16 branches here and 101 non-merge changesets, the majority of which are for the stedma40 dma engine driver used in the ux500 platform. Cleaning up that code touches multiple subsystems, but gets rid of the dependency in the end. The mailbox code moved out from mach-omap2 to drivers/mailbox is an intermediate step and is still omap specific at the moment. Patches exist to generalize the subsystem and add other drivers with the same API, but those did not make it for 3.11." * tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (101 commits) crypto: ux500: use dmaengine_submit API crypto: ux500: use dmaengine_prep_slave_sg API crypto: ux500: use dmaengine_device_control API crypto: ux500/crypt: add missing __iomem qualifiers crypto: ux500/hash: add missing static qualifiers crypto: ux500/hash: use readl on iomem addresses dmaengine: ste_dma40: Declare memcpy config as static ARM: ux500: Remove mop500_snowball_ethernet_clock_enable() ARM: ux500: Correct the EN_3v3 regulator's on/off GPIO ARM: ux500: Provide a AB8500 GPIO Device Tree node gpio: rcar: fix gpio_rcar_of_table gpio-rcar: Remove #ifdef CONFIG_OF around OF-specific sections gpio-rcar: Reference core gpio documentation in the DT bindings clk: exynos5250: Add enum entries for divider clock of i2s1 and i2s2 ARM: dts: Update Samsung I2S documentation ARM: dts: add clock provider information for i2s controllers in Exynos5250 ARM: dts: add Exynos audio subsystem clock controller node clk: samsung: register audio subsystem clocks using common clock framework ARM: dts: use #include for all device trees for Samsung pinctrl: s3c24xx: use correct header for chained_irq functions ...
