Merge tag 'imx6q-cpudile-3.9' of git://git.linaro.org/people/shawnguo/linux-2.6 into next/soc
From Shawn Guo:
imx6q cpuidle support for 3.9
- It's based on imx-cleanup-3.9 to avoid conflicts.
* tag 'imx6q-cpudile-3.9' of git://git.linaro.org/people/shawnguo/linux-2.6:
ARM: imx6q: support WAIT mode using cpuidle
ARM: imx: move imx6q_cpuidle_driver into a separate file
ARM: imx: mask gpc interrupts initially
ARM: imx: return zero in case next event gets a large increment
ARM: imx: Remove mx508 support
ARM: imx: Remove mach-mx51_3ds board
ARM: imx: use debug_ll_io_init() for imx6q
ARM: imx: remove unused imx6q_clock_map_io()
ARM: mach-imx: Kconfig: Do not select Babbage for MACH_IMX51_DT
