* ARM: mx53: Allow suspend/resumeFabio Estevam2013-08-221-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current imx53_pm_init() implementation is incomplete as it lacks calling suspend_set_ops(). Use a single imx5_pm_init() function to handle both mx51 and mx53. This allows mx53 to enter in low-power mode. Tested on a mx53qsb: root@freescale /$ echo mem > /sys/power/state PM: Syncing filesystems ... done. mmc0: card e624 removed Freezing user space processes ... (elapsed 0.001 seconds) done.

* ARM: imx: cpuidle: use init/exit common routineDaniel Lezcano2013-04-231-28/+1
| | | | | | | | | | | | | | | The code intializes the cpuidle driver at different places. The cpuidle driver for : * imx5 : is in the pm-imx5.c, the init function is in cpuidle.c * imx6 : is in cpuidle-imx6q.c, the init function is in cpuidle.c and cpuidle-imx6q.c Instead of having the cpuidle code spread across different files, let's create a driver for each SoC and use the common register function.

| | | | | | | | | | | The en_core_tk_irqen flag is set in all the cpuidle driver which means it is not necessary to specify this flag. Remove the flag and the code related to it.

* ARM: imx: Remove mx508 supportFabio Estevam2013-01-291-5/+2
| | | | | | | | | | | | | Only mx508 based board is mach-mx50_rdp and it has been marked as BROKEN for several releases. mx508 currently lacks clock support. In case someone needs to add mx508 support back, then the recommended approach is to use device tree.

* ARM: imx: include hardware.h rather than mach/hardware.hShawn Guo2012-10-151-1/+1
| | | | | | | | | | | 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".

* ARM: imx: Enable imx53 low power idleRobert Lee2012-06-051-0/+5
| | | | | | | | | | 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.

* ARM: imx: clean and consolidate imx5 suspend and idle codeRobert Lee2012-06-051-26/+41
| | | | | | | | | | | | | | | | | | | | | | | | 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.

I'm merging the MX 5 consolidation, since it apparently will help the next development window and will avoid conflicts later as per Arnd.

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.
