In LPAPM mode, DDR is sourced from 24MHz OSC. Since only ARM clock is
sourced from PLL1, relock it to 160MHz to save some power.

- Current default temp index is 8, which causes issues for panels with only 1
temperature index. So if no temp index is found to match the temperature,
use a default of 0 to ensure that a valid index is used for these special
waveform types.
- Firmware loading changed from blocking to non-blocking to allow EPDC
driver to boot without waiting.

No INT generation in Multi-blk operations bug of MX50 TO1.0
and MX53 TO1.0 had been fixed in MX50 TO1.1 and MX53 TO2.
Keep the SW workaround for MX50 TO1.0 and MX53 TO1.0.
And use the solution adviced by IC team for MX50 TO1.1 and MX53 TO2.
About the details of this IC bug, pls refer to following errata

The usb wakeup thread should be prior to usb system resume
during usb wakeup process. It adds wait_event_interruptible
at usb resume process, and the usb wakeup irq will set event,
and the usb wakeup thread will clear event.

If GPU error interrupt detected, related device will be destroyed.
In the destory function, device_idle and mutex_lock may cause sleep,
which may cause kernel crash, so delay the device destroy to the
workqueue to avoid this.

This is required by SD2 card detection function.
The root cause is that the power for SD2 card detection pull up
is the same as the SD2 I/O power, they are all supplied by VSD
regulator. If we disable VSD dynamically, the card will never be
able to be detected again.

Since the device suspend timing driver is
default set to off, so add it to default config of mx5, mx3.
If you want to debug your driver's suspend / resume
timing, please enable it by write time in microsecond.

the default state of suspend driver is default off,
if you want to debug the suspend time, echo time in
microsecond(u Second) to /sys/powe/device_suspend_time_threshold
eg: I want to know which driver suspend & resume takes
more that 0.5 ms (500 us), you can just :
ehco 500 > /sys/power/device_suspend_time_threshold

FB_SYNC_EXT was used to represent ext clk, but actually, it represent ext sync.
Some applications do not recognize it, during fb_set_var ioctl may miss it,
which will cause fb display fail, for example X window startup.
Remove FB_SYNC_EXT flag, and choose ext clk support by ipu driver.
If you want to use ipu internal clk only, you can add int_clk to your video
option like below:
video=mxcdi0fb:RGB565,800x480M@55,int_clk

There was some driver is slow on suspend/resume,
but some embeded system like eReader,Cellphone
are time sensitive,this commit will report the slow
driver on suspend/resume, the default value is 500us(0.5ms)
Also, the threshold can be change by modify
'/sys/power/device_suspend_time_threshold' to change the threshold,
it is in microsecond.
The output is like:
PM: device platform:soc-audio.2 suspend too slow, takes 606.696 msecs
PM: device platform:mxc_sdc_fb.1 suspend too slow, takes 7.708 msecs

Implemented the following:
1) Code to check mDDR v LPDDR2 memory type
2) For mDDR, changed DATABAHN register values for 24 MHz DDR clock
3) For mDDR, changed DATABAHN register values when clock is changed
back to 200 MHz in Async mode.
Note that this code is untested on TO 1.1.

The buffer mil->auxiliary_virt only have nfc_goe->auxiliary_size_in_bytes bytes
