1 close clock when asrc is not working.
2 enable the asrc core clock when user sucessfully request an
ASRC pair and disable it when the pair is release.So the call
from ESAI using the p2p DMA mode can be support.

If the usb remote wakeup occurs before bus(roothub) suspend, it can
stop the system suspend process, the patch adds handle error message
process for roothub.
If the remote wakeup occurs after bus(roothub) suspend, then
the suspend will go on suspending, and usb phy will fail to respond
wakeup signal.
This patch is suggested by: Alan Stern <stern@rowland.harvard.edu>

fix some build warnings when using GCC 4.6.2:
arch/arm/mach-mx6/board-mx6q_sabresd.c:1588:20:
warning: function declaration isn't a prototype [-Wstrict-prototypes]
This patch also fix the following section mismatch warnings:
The function imx6q_init_audio() references
the variable __initconst imx6_imx_ssi_data.
This is often because imx6q_init_audio lacks a __initconst
annotation or the annotation of imx6_imx_ssi_data is wrong.

- Without host wakeup enable, after doing system suspend/resume,
plug in usb cable(both host/device) with no response, the reason is
usb wakeup is not enable after suspend resume.
- clock refcount will not be 0 after usb enters low power mode,the
reason is OTG ID wake up not do recover hcd.

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.

test with
video=mxcfb0:dev=sii902x_hdmi,1024x768M@60,if=RGB24 disable_mipi_dsi
Note:
1. currently we use the same ipu setting port with on chip HDMI,
if we need coexist need change the on chip HDMI ipu settings.
2. need remove MIPI DSI initial with 'disable_mipi_dsi' in kernel command line,
as mipi dsi reset will reset on board sii902x as well.
3. change the I2C2 work at 100K not 400K, to be compatible with EDID spec.
4. the side effect is that Sii902x will have to use "sii902x_hdmi",
instead of "hdmi" as before
