Merge tag 'mxs-cleanup-3.10' of git://git.linaro.org/people/shawnguo/linux-2.6 into next/cleanup
From Shawn Guo <shawn.guo@linaro.org>:
The mxs cleanup for 3.10:
* Clean up timer code and move it into drivers/clocksource
* Clean up icoll code and move it into drivers/irqchip
* Clean up clock code to not include <mach/*> headers
* Clean up rtc-stmp3xxx, mxs-lradc and mxs-saif to not include <mach/*>
headers
* Clean up mach-mxs code to get it prepared for multiplatform support
* tag 'mxs-cleanup-3.10' of git://git.linaro.org/people/shawnguo/linux-2.6: (26 commits)
