This patch will do the following:
1. For mlb will not be able to know whether the final package is
completely sent, add a delay for final package to be sent.
2. Adjust MLB's iram buffer usage. Old code will add addtional
usage of iram buffer.
3. Code format change.
4. In resume function, calling init function after clock is enabled.

Add global value gpu3DMinClock so that minimum 3D clock can be change by user.
When gpu min clock is too low, it may cause IPU starvation issue in certain case.

To avoid NULL interrupt handler being called potentially in the
IPU sync interrupt source handler, this patch adds sanity check
on NULL interrupt handler in the function ipu_request_irq() for
sync interrupts because the callers are likely to request a sync
interrupt without specifying a handler. The error interrupts can
still be enabled by this function without this kind of sanity
check since we simply print out the relevant error interrupt
register values in the IPU error interrupt source's handler.
This patch also corrects _ipu_get() and _ipu_put() function call
in the function ipu_request_irq() to make them be called in pair
when handler has already been registered.

This patch corrects the formulae to calculate uv offset for
several non-tiled planar yuv pixel formats:
1) NV12(partial interleaved):
A part of the formula does math in this way: (width * pos_y)/2.
This is wrong for odd crop pos_y. We should rigidly get half
of crop pos_y and then have the result multiply stride(in this
case, width) instead: width * (pos_y/2). The issue could be
reproduced by the following unit test case:
/unit_tests/mxc_v4l2_output.out -iw 1024 -ih 768
-cr 496, 377, 264, 195 -ow 1024 -oh 768 -fr 30
-f NV12 ./test_nv12_xga.yuv
2) YUV420/YVU420(non-interleaved):
Similar to NV12, the wrong part '(width/2 * pos_y/2)' should
be changed to '(width/2) * (pos_y/2)', otherwise, odd crop
pos_y would cause wrong uv offset. Moreover, although height
should be a muliply of 2 according to the IPUv3 spec, it still
probably can process frames with odd height, i.e, the last y
line might consume an additional line for u and v respectively.
So, this patch rounds up height to even value by '(height+1)',
which doesn't hurt in any way. The issue could be reproduced
by the following unit test case:
/unit_tests/mxc_v4l2_output.out -iw 1024 -ih 768
-cr 496, 378, 272, 195 -ow 1024 -oh 768 -fr 30
./test_yuv420_xga.yuv
3) YUV422/YVU422(non-interleaved):
Within the context, the width parameter in the function
update_offset() is equal to stride line. The function
ipu_init_channel_buffer() requires stride line to be 4-byte
aligned, so, for this part, code change only is done without
any logic modification to make the calculation be straightforward
to be understood.

The thermal sensor's value will be updated even it is power down,
as thermal sensor's clock source is from PLL3, so there is chance
that PLL3 is disabled before thermal driver is probed during kernel
boot up, so the value in thermal sensor can be incorrect in this
PLL3 disabled window.
Previous flow of thermal driver probe routine will enable PLL3
clock, then set the thermal alarm value and enable the alarm irq,
there is no delay or check about the thermal sensor's value, only
when the thermal sensor's value is correct, its alarm function
can be enabled. As adding delay in the probe routine is not a
good option, so we move the enabling of thermal alarm function
into the get temperature routine, as after the thermal value is
read, the alarm function is safe enough, as the thermal sensor
will be always working right after a read if its clock is enabled.

Change async's ring buffer size from 2048 to 1536(MEP package size) and

in async mode reduced from 34816 to 24576.

Use circle buf to replace old ringbuf mechanism.
Change to use circle buffer in read, write, rx isr and tx isr functions.
In first design of MLB, it's using it's own mechanism to manage ring
buffer, like in mxc_mlb.c.
And then, I saw that kernel already had a serials of circ buffer macros
which can be used to manage ring buffers.
This patch is to use circle buffer macros to manage mlb internal ring
buffers.
For detail of circle buffers, you can refer to
linux-2.6-imx/Documentation/circular-buffers.txt.

Reset whole CDR in init function. This will make mlb connection to MITB

This is a missed part in mx6 rm's mlb section, but new in mlb's latest
spec DS62420AP2.pdf 12.1.1-1.

For both CSI_MEMx and CSI_PRP_VF(ENC)_MEM capture channels,
we disable them with the following sequence:
1) Wait for an idmac channel eof interrupt.
2) Disable CSI by clearing CSIx_EN in IPU_CONF register.
3) Disable idmac channel by clearing relevant bit in
IPU_IDMAC_CH_EN_1 register and other settings.
However, currently, we don't do 3) until CSI_PRP_VF(ENC)_MEM's
idmac channel being not busy by a while loop check. In case, an
external sensor is plugged out from the system or the sensor is
somehow broken, we will be unable to get out of that infinite
while loop. Since this check is unnecessary(we've already
waited for an idmac eof interrupt), this patch simply removes
it from the disable routine of CSI_PRP_VF(ENC)_MEM channel.
