IPU's IC/IRT/VDI modules provide resizing/CSC/combination/de-interlacing
support, this patch make all these features into one processing driver.
A struct ipu_task is the interface between user and this driver, user
just need fill his task struct and queue it through ioctl, then wait
ipu hardware finish its job (now only support BLOCKING operation, not
support NO_BLOCK operation).
Pls refer to inlcude/linux/ipu.h for structure information and unit test
for usage.
This patch is for ipu driver changes.

When setup irq is received, the status phase of the transfer is primed
on ep0 before the data phase. The usb requests are added to the list
of transfer descriptors (maintained by driver) in reverse of their
expected completion order. Completion order is data followed by status,
however the list of tds contains status followed by data.
Upon completion of the data request, the irq handler proceeds to check
the 1st td in the list -- the status request. In full speed mode,
the status phase has not yet completed at this time, so the td's
ACTIVE bit is still set. This leads irq handler to ignore the completion
interrupt without checking the actual td for the data request that caused
the interrupt.
In high speed mode, this issue does not bear itself out because the status
request also completes by the time the irq handler goes to process the data
completion interrupt.
The simple fix for this issue is to prime the status request AFTER the data
request, so that the list of tds maintained by the driver contains the tds
in the order of expected completion.

Current thermal reading formula is not accurate,
and different board has different value, previous
setting of trip point setting is too low, and some
boards can reach hot and critical point easily, so
change the trip point as below:
critical : 50 -> 100 C
hot : 40 -> 90 C
active : 30 -> 80 C
these trip points value can also be changed via echo
an value into /sys/class/thermal/thermal_zone0/trip..

This patch introduces the helper of ehci_sync_mem to flush
qtd/qh into memory immediately on some ARM, so that HC can
see the up-to-date qtd/qh descriptor asap.
This patch fixs one performance bug on ARM Cortex A9 dual core
platform, which has been reported on quite a few ARM machines
(OMAP4, Tegra 2, snowball...), see details from link of
https://bugs.launchpad.net/bugs/709245.
The patch has been tested ok on OMAP4 panda A1 board, and the
performance of 'dd' over usb mass storage can be increased from
4~5MB/sec to 14~16MB/sec after applying this patch.

1.Common code of thermal_sys has some bug,could
not set the mode via sysfs using echo enable/disabled
command;
2.Since the anatop thermal formula still not accurate,
in order to help test and adjust the trip point of
anatop thermal zone, we add the set trip point temp
value into the sysfs interface.

in uSDHC controller, SDCLKFS field in SYS_CTRL register
is defined differently from eSDHC
In Single Data Rate mode(DDR_EN bit of MIXERCTRL is '0')
Only the following settings are allowed:
80h) Base clock divided by 256
40h) Base clock divided by 128
20h) Base clock divided by 64
10h) Base clock divided by 32
08h) Base clock divided by 16
04h) Base clock divided by 8
02h) Base clock divided by 4
01h) Base clock divided by 2
00h) Base clock divided by 1
While in Dual Data Rate mode(DDR_EN bit of MIXERCTRL is '1')
Only the following settings are allowed:
80h) Base clock divided by 512
40h) Base clock divided by 256
20h) Base clock divided by 128
10h) Base clock divided by 64
08h) Base clock divided by 32
04h) Base clock divided by 16
02h) Base clock divided by 8
01h) Base clock divided by 4
00h) Base clock divided by 2

At armv7 SoC, the dma_alloc_coherent returns non-cachable, but
bufferable region, so the driver needs to drain write buffer by
itself, if the controller needs to visit dma buffer immediately
after cpu writes
There is a discussion for this armv7 change:
http://marc.info/?t=127918539100004&r=1&w=2
For this issue, the next dtd pointer is invalid sometimes, the reason
is the region which is used to store dtd is dma buffer, so the data may
not be written to memory when the controller visit this data.

make ldb support two ipu in separate mode
cmdline option changed:
"ldb=spl0/1" -- split mode on DI0/1
"ldb=dul0/1" -- dual mode on DI0/1
"ldb=sin0/1" -- single mode on LVDS0/1
"ldb=sep0/1" -- separate mode begin from LVDS0/1
there are two LVDS channels(LVDS0 and LVDS1) which can transfer video
datas, there two channels can be used as split/dual/single/separate mode.
split mode means display data from DI0 or DI1 will send to both channels
LVDS0+LVDS1.
dual mode means display data from DI0 or DI1 will be duplicated on LVDS0
and LVDS1, it said, LVDS0 and LVDS1 has the same content.
single mode means only work for DI0/DI1->LVDS0 or DI0/DI1->LVDS1.
separate mode means you can make DI0/DI1->LVDS0 and DI0/DI1->LVDS1 work
at the same time.

UART hold the following locks in order of:
imx_set_termios():
--> spin_lock_irqsave(&sport->port.lock, flags)
del_timer_sync(&sport->timer);
--> spin_lock(timer->base->lock);
--> spin_unlock(timer->base->lock);
spin_unlock_irqrestore(&sport->port.lock);
while when imx_timeout() may invoked in following stack:
run_timer_softirq():
--> spin_lock_irqsave(timer->base->lock, flags);
imx_timeout();
--> spin_lock_irqsave(&sport->port.lock, flags);
...;
--> spin_unlock_irqrestore(&sport->port.lock, flags);
spin_unlock_irqrestore(timer->base->lock, flags);
the above two cases hold lock with revert order, may
deadlock in SMP platform.
