Linus Torvalds 8b45bc892e ARM: SoC driver updates for 3.18
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
