Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver updates from Arnd Bergmann: "These are changes for drivers that are intimately tied to some SoC and for some reason could not get merged through the respective subsystem maintainer tree. Most of the new code is for the Keystone Navigator driver, which is new base support that is going to be needed for their hardware accelerated network driver and other units. Most of the commits are for moving old code around from at91 and omap for things that are done in device drivers nowadays. - at91: move reset, poweroff, memory and clocksource code into drivers directories - socfpga: add edac driver (through arm-soc, as requested by Boris) - omap: move omap-intc code to drivers/irqchip - sunxi: added an RTC driver for sun6i - omap: mailbox driver related changes - keystone: support for the "Navigator" component - versatile: new reboot, led and soc drivers" * tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (92 commits) bus: arm-ccn: Fix spurious warning message leds: add device tree bindings for register bit LEDs soc: add driver for the ARM RealView power: reset: driver for the Versatile syscon reboot leds: add a driver for syscon-based LEDs drivers/soc: ti: fix build break with modules MAINTAINERS: Add Keystone Multicore Navigator drivers entry soc: ti: add Keystone Navigator DMA support Documentation: dt: soc: add Keystone Navigator DMA bindings soc: ti: add Keystone Navigator QMSS driver Documentation: dt: soc: add Keystone Navigator QMSS bindings rtc: sunxi: Depend on platforms sun4i/sun7i that actually have the rtc rtc: sun6i: Add sun6i RTC driver irqchip: omap-intc: remove unnecessary comments irqchip: omap-intc: correct maximum number or MIR registers irqchip: omap-intc: enable TURBO idle mode irqchip: omap-intc: enable IP protection irqchip: omap-intc: remove unnecesary of_address_to_resource() call irqchip: omap-intc: comment style cleanup irqchip: omap-intc: minor improvement to omap_irq_pending() ...
