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)

  ARM: mxs: remove unused headers
  ARM: mxs: merge imx23 and imx28 into one machine_desc
  ARM: mxs: remove common.h
  ARM: mxs: move mxs_get_ocotp() into mach-mxs.c
  ARM: mxs: remove mm.c
  ARM: mxs: use debug_ll_io_init for low-level debug
  ARM: mxs: get ocotp base address from device tree
  ARM: mxs: remove system.c
  ARM: mxs: get reset address from device tree
  ARM: mxs: remove empty hardware.h
  ASoC: mxs-saif: remove mach header inclusion
  iio: mxs-lradc: remove unneeded mach header inclusion
  rtc: stmp3xxx: use stmp_reset_block() instead
  clk: mxs: remove the use of mach level IO accessor
  clk: mxs: get base address from device tree
  ARM: mxs: remove unneeded mach-types.h inclusion
  ARM: mxs: move icoll driver into drivers/irqchip
