dual camera support for mx6q and mx6dl:
1. let mipi and parallel camera working on different csi
2. the two camera can work independently and synchronously
3. the two camera will be registered and different video
device(/dev/video0, /dev/video1)
4. when both camera are working, the can not use the same
ipu channel, that is, when camera one using PRP_ENC_MEM
or PRP_VF_MEM channel, the other one can only use CSI_MEM
this is the driver part.

It is cause by HDMI audio driver can't get right pixel clock
from IPU driver if pixel clock source from HSP clock not from
DI clock.
HDMI driver get pixel clock by call clk_get_rate() function,
but the function return actually clock, in some videomode the
actually pixel clock is not right equal the pixel clock in CEA spec.
Get pixel clock from video mode struct instead of CCM register.
480P HDMI audio can work.

This patch includes some of the clk enable/disable changes from rev2
Check the version of the HDMI IP to determine whether the fifo
threshold needs to be high. The i.Mx6dl version of the HDMI doesn't
need the workaround. All other parts of the workaround are used
for both parts for code simplicity.
----------------------------------------------------------
For i.Mxq, set the Threshold of audio fifo as: FIFO depth - 2 (fixed
and independent of the number of channels actually used).
Use unspecified length ahb bursts (using fixed INCRx will make the
audio dma fail).
Additionally and in order to get it working on all conditions it will
be necessary to run the following sw steps at startup of video and audio
(or when video changes or audio changes):
1-Configure AUD_N1 and AUD_CTS1 registers with final value and let the
AUD_N2, AUD_N3, AUD_CTS2 and AUD_CTS3 to 0s.
2-Configure start and end addresses of audio DMA registers.
3-Start DMA operation
4-Configure the AUD_CTS2 and AUD_CTS3 with the final value.
5-Configure the AUD_N2 and AUD_N3 with final value.

Add irq count to CPUFreq as a freq change condition.
Because some devices' working mode is unable to issue
CPUFreq change because of low CPU loading, but the cpu
freq will impact these devices' performace significantly.
Interactive govervor will sample the cpu loading as well
as the irq count which is registered. If the
loading or the irq count exceed the threshold we set,
governor will issue an CPUFreq change request.
These devices' irq threshold and enable/disable can be modified
via /sys/devices/system/cpu/cpufreq/interactive/irq_scaling
echo 0xAABBBC to change the default setting as below
AA : irq number
BBB: threshold
C :enable or disable
Currently only enable USDHC3, USDHC4, GPU, SATA and
USB by default, we can add device to the init struct which is
located in arch/arm/mach-mx6/irq.c.

cpufreq: interactive: New 'interactive' governor
This governor is designed for latency-sensitive workloads, such as
interactive user interfaces. The interactive governor aims to be
significantly more responsive to ramp CPU quickly up when CPU-intensive
activity begins.
Existing governors sample CPU load at a particular rate, typically
every X ms. This can lead to under-powering UI threads for the period of
time during which the user begins interacting with a previously-idle system
until the next sample period happens.
The 'interactive' governor uses a different approach. Instead of sampling
the CPU at a specified rate, the governor will check whether to scale the
CPU frequency up soon after coming out of idle. When the CPU comes out of
idle, a timer is configured to fire within 1-2 ticks. If the CPU is very
busy from exiting idle to when the timer fires then we assume the CPU is
underpowered and ramp to MAX speed.
If the CPU was not sufficiently busy to immediately ramp to MAX speed, then
the governor evaluates the CPU load since the last speed adjustment,
choosing the highest value between that longer-term load or the short-term
load since idle exit to determine the CPU speed to ramp to.
A realtime thread is used for scaling up, giving the remaining tasks the
CPU performance benefit, unlike existing governors which are more likely to
schedule rampup work to occur after your performance starved tasks have
completed.
The tuneables for this governor are:
/sys/devices/system/cpu/cpufreq/interactive/min_sample_time:
The minimum amount of time to spend at the current frequency before
ramping down. This is to ensure that the governor has seen enough
historic CPU load data to determine the appropriate workload.
/sys/devices/system/cpu/cpufreq/interactive/go_maxspeed_load
The CPU load at which to ramp to max speed.

Some host controllers will not operate without a hardware
timeout that is limited in value. However large discards
require large timeouts, so there needs to be a way to
specify the maximum discard size.
A host controller driver may now specify the maximum discard
timeout possible so that max_discard_sectors can be calculated.
However, for eMMC when the High Capacity Erase Group Size
is not in use, the timeout calculation depends on clock
rate which may change. For that case Preferred Erase Size
is used instead.

Previously there has only been one function mmc_wait_for_req()
to start and wait for a request. This patch adds:
* mmc_start_req() - starts a request wihtout waiting
If there is on ongoing request wait for completion
of that request and start the new one and return.
Does not wait for the new command to complete.
This patch also adds new function members in struct mmc_host_ops
only called from core.c:
* pre_req - asks the host driver to prepare for the next job
* post_req - asks the host driver to clean up after a completed job
The intention is to use pre_req() and post_req() to do cache maintenance
while a request is active. pre_req() can be called while a request is
active to minimize latency to start next job. post_req() can be used after
the next job is started to clean up the request. This will minimize the
host driver request end latency. post_req() is typically used before
ending the block request and handing over the buffer to the block layer.
Add a host-private member in mmc_data to be used by pre_req to mark the
data. The host driver will then check this mark to see if the data is
prepared or not.

Add functionality to parse Audio Data Blocks from EDID data to
find out what modes of LPCM are suppored by the HDMI sink device.
The parsed settings are saved in the hdmi mfd. The HDMI audio driver
will check the settings when the audio stream is opened and will
then apply appropriate constraints.
If we are unable to read from the EDID, then we default to supporting
Basic Audio as defined by the HDMI specification (stereo, 16 bit,
32KHz, 44.1KHz, 48KHz PCM).
