After using POR reset, the content in SRC will be reset.
See RM: 63.5.1.2.3 IPP_RESET_B(POR)
Because POR reset will reset most of register in IC, so use
SNVS_LP General Purpose Register (LPGPR) to store the boot mode value.
Below copy from SNVS_BlockGuide.pdf:
The SNVS_LP General Purpose Register provides a 32 bit read write
register, which can be used by any application for retaining 32 bit
data during a power-down mode
This Patch will use [7,8] bits of this register.

Android CTS verifier have a must requirement for YV12 format. Since IPUv3
common driver has supported IPU_PIX_FMT_YVU420P pixel format, add the
support of YV12 format in mxc_v4l2_capture.

1. Refine VPU suspend/resume according to open_count to completely
fix bug: ENGR00230203 [Android_MX6DL_SD] Gallery: System hang
after resume from suspend during video playback. 20%
open_count == 0 case can be simplified because VPU is released
(all instances are freed), so
- clock is already off
- context is no longer needed
- power is already off on MX6
VPU reset is removed from resume because power is ensured to be off
before entering resume on MX6 by calling regulator API.
2. Fix bug: VPU always busy after suspend/resume
Error log (VPU refused to suspend due to VPU busy):
pm_op(): platform_pm_suspend+0x0/0x54 returns -11
PM: Device mxc_vpu failed to suspend: error -11
PM: Some devices failed to suspend
Root cause:
- Suspend happened during vpu_Init(), somewhere after VPU lib started
to download FW (when PC == 0), but before run FW. (BIT_BUSY_FLAG=1,
BIT_CODE_RUN=1).
- In such case, VPU resume downloaded FW and run VPU to idle because
suspend was triggered after VPU was opened (active).
- vpu_Init run VPU again with BIT_BUSY_FLAG=1. So VPU was trapped in
idle loop but BIT_BUSY_FLAG was never cleared. VPU lib regarded VPU
as always busy.
Solution (in VPU resume):
- run VPU FW only if VPU was opened and PC before suspend is not 0
- restore host register is required
- download FW is required, because program memory is lost after power
off.

USB does not work when plug in a usb device during system suspend. Under this
case, USB driver will be in low power mode, but WIE bit not be set if usb wake
up is not enabled.So there are only ID change interrupt no USB wakeup interrupt
after system resume.In current bsp, after system resume ID change status not be
clear,and ID change interrupt will continue happen, which cause the system busy.
No checking WIR bit if ID change interrupt happen when USB in low power mode to
fix this issue.

- It is better to disable otgsc and wake up interrupt to avoid an
abnormal interrupt happen during USB driver being removed.
- If the USB host is already at low power mode, only need turn on
the clock, no need turn off the clock.
- Need discharge dp and dm during USB driver being removed ,in order
to avoid a wakeup interrupt happen. And if the USB otg is in host
mode, we should clear discharge dp and dm in fsl_otg_set_host()
during system boot up.

The job ring driver exhibited a hang condition in the top of
caam_jr_dequeue() where a BUG_ON statement looks for a condition
where the output ring is said to have valid entries by the ring logic,
but the ring entries apparently have NULL descriptor pointers.
In the initial ARM port of this driver, the cache flush call
of the output ring content occured before the output ring read index
register read occurred, exposing a condition where the driver sensed valid
output entries, yet the entries written by the ring hardware were not
invalidated, and therefore were not visible to the processor, appearing
as false NULL entries.
This patch relocates the invalidate call to immediately follow the
check of the output read index, where it is required.

Didn't take more care about non-pfuze board, and there is two place in BSP will
call "mx6_cpu_regulator_init". It means regulator_get will be called twice on
every vddcore/vddsoc regulator. Then one value need set twice ,because from
regulator core view, there is two regulators share the same regulator. The non-
validate one will return error and print "COULD NOT SET GP VOLTAGE!!!!." on
Sabreauto board. The same as Sabrelite and ARM2 board.
Meanwhile, Sabreauto need be configured LDO bypass default.

This bug was introduced by ENGR00229290 which fixed
the problem of greater than 16 LUTs used when 5-bit
waveform loaded. The bug is that now the driver is also
restricted to using 16 LUTs in 4-bit mode.
The fix is to correct the test of the EPDC_FORMAT
register used to determine if a 5-bit waveform
is loaded.
Also removed the while loop in favor of a bitwise OR
used to determine if a chosen LUT has yet to be
acknowledged by the interrupt handler.
