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.

Robert Lee 565fa91f23 ARM: imx: clean and consolidate imx5 suspend and idle code
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.

Fabio Estevam bb07d7511e ARM: mx3: Setup AIPS registers
It was observed on a mx31pdk board that audio playback only worked when the bootloader was Redboot, and
did not work when U-boot was used.

Comparing the sources of these bootloaders showed that the AIPS registers were not setup in U-boot.

Instead of relying on the bootloader to setup the AIPS registers, do it in the kernel so that audio
playback can work independantly of the bootloader being used.

Copied the AIPS settings from Redboot to the kernel.

Fabio Estevam 3ac804e311 ARM: mx3: Let mx31 and mx35 enter in LPM mode in WFI
The LPM field of register CCMR is used to select the mode that the processor will run
when it goes to WFI.

When mx31 enters in WFI mode the LPM field is at its reset value of 0,
which configures the mx31 to enter in "wait mode".

On mx35, the LPM field on mx35 is also at 0 after reset, which corresponds
to "run mode" instead of "wait mode".

Instead of relying on the reset value of LPM to set the low power mode for
WFI, configure mx31 and mx35 to run in "wait mode"

Introduce a generic function for this purpose, so that all i.MX processors can

Shawn Guo e7fc6ae744 gpio/mxc: get rid of the uses of cpu_is_mx()
The patch removes all the uses of cpu_is_mx().  Instead, it utilizes
platform_device_id to distinguish the different gpio types, IMX1_GPIO
on i.mx1, IMX21_GPIO on i.mx21 and i.mx27, IMX31_GPIO on all other
i.mx SoCs.

Shawn Guo b78d8e59a6 gpio/mxc: Change gpio-mxc into an upstanding gpio driver
The patch makes necessary changes on gpio-mxc as below to turn it
into an upstanding gpio driver.

 * Add a list to save all mx2 ports references, so that
   mx2_gpio_irq_handler can walk through all interrupt status
   registers

 * Use readl/writel to replace mach-specific accessors
   __raw_readl/__raw_writel

 * Change mxc_gpio_init into mxc_gpio_probe function

 * Move "struct mxc_gpio_port" into gpio-mxc.c, as it needs not to
   be public at all, and also make some other cleanup on
   plat-mxc/include/mach/gpio.h at the same time

And the patch then migrates mach-imx and mach-mx5 to the updated
driver by adding corresponding platform devices.

Since support for mxc91231 was introduced 2009 it only saw patches that
were part of (mxc or arm) global cleanups. The only supported machine
only had 4 devices (2x UART, sdhc, watchdog).
