2012-10-15ARM: imx: include hardware.h rather than mach/hardware.hShawn Guo
It moves a bunch of header files included in hardware.h and itself from mach-imx/include/mach to mach-imx, and updates users to include hardware.h rather than mach/hardware.h. The files in mach-imx/devices will need to include "../hardware.h".

2012-10-15ARM: imx: ARM: imx: include cpuidle.h rather than mach/cpuidle.hShawn Guo
Rename mach-imx/include/mach/cpuidle.h to mach-imx/cpuidle.h, and update users to include cpuidle.h rather than mach/cpuidle.h. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Sascha Hauer <s.hauer@pengutronix.de> Acked-by: Arnd Bergmann <arnd@arndb.de>
2012-10-15ARM: imx: include common.h rather than mach/common.hShawn Guo
Rename mach-imx/include/mach/common.h to mach-imx/common.h and update all users to include common.h rather than mach/common.h. It also removes an unneeded inclusion to common.h in mach-imx/devices/devices.c.

2012-06-05ARM: imx: Enable imx53 low power idleRobert Lee
Add various functionality needed to enable a imx53 low power idle state. This includes adding the imx53 gpc_dvfs clock and making a common imx5_late_init function and initializing all imx53 MACHINE_STATE late_init calls to imx5_late_init.

2012-06-05ARM: imx: clean and consolidate imx5 suspend and idle codeRobert Lee
The imx5 idle code that existed in mm-imx5.c is moved to pm-imx5.c. The imx5_pm_init call is now exported and called during the MACHINE_START late_init in supported imx5 platforms. Remove various enabling/disabling of the gpc_dvfs clock and enable it once during initialization. This is a very low power clock that must be enabled during low power operations. There are only two "suspend_state_t" imx5 low power modes ever used. STOP_POWER_OFF for suspend to mem and WAIT_UNCLOCKED_POWER_OFF for idle and suspend to standby. The latter mode only requires 500 nanoseconds of extra hardware exit time beyond a basic WFI operation (WAIT_CLOCKED mode) so no other idle mode is necessary. Given this information, it is more efficient to keep the registers in the often used WAIT_UNCLOCKED_POWER_OFF state and only to and from the STOP_POWER_OFF register state as needed when suspend to mem is required.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Consolidate i.MX 5 platforms to be under the new shared i.MX 3/5/6 tree. * tag 'arm-soc-imx-move' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM i.MX: Update defconfig ARM i.MX: Merge i.MX5 support into mach-imx ARM i.MX5: remove unnecessary includes from board files Fix up fairly trivial conflicts due to various changes nearby in arch/arm/{mach,plat}-imx/{Kconfig,Makefile} Pull request had been sent to the wrong email address, but happened before the merge window closed. I'm merging the MX 5 consolidation, since it apparently will help the next development window and will avoid conflicts later as per Arnd.
2011-11-16ARM i.MX: Merge i.MX5 support into mach-imxSascha Hauer
This patch moves the contents of arch/arm/mach-mx5 to arch/arm/mach-imx and adjusts the Makefile/Kconfig entries in a way that it's possible to compile i.MX5 together with i.MX3/6.
