The following patch adds support for the Tongwei Video Technology TD-3116 board. This
is a Bt878 based capture card with 16 inputs meant for surveilance applications.
It also offers a way to check which inputs have a video signal while capturing another
input. In addition there are a number of alarm inputs and outputs available and there
is microcontroller which is presumably intended for use as a system watchdog. None of
these extra capabilities are supported by the patch.

when the irq had not yet been requested. In those cases, the call to

The ADV7170/ADV7171 can operate in either 8-bit or 16-bit YCrCb Mode.
* 8-Bit YCrCb Mode
This default mode accepts multiplexed YCrCb inputs through
the P7-P0 pixel inputs. The inputs follow the sequence Cb0, Y0
Cr0, Y1 Cb1, Y2, etc. The Y, Cb and Cr data are input on a
rising clock edge.
* 16-Bit YCrCb Mode
This mode accepts Y inputs through the P7–P0 pixel inputs and
multiplexed CrCb inputs through the P15–P8 pixel inputs. The
data is loaded on every second rising edge of CLOCK. The inputs
follow the sequence Cb0, Y0 Cr0, Y1 Cb1, Y2, etc.

The RGB mode does not work correctly. It captures fine at 640x480
but whenever the scaling engine is used to produce another resolution,
color corruption occurs (lots of erroneous pink and green).
It is not clear how the scaling engine is supposed to work and how
it knows which pixel format it is dealing with. Work around this
problem by disabling RGB support. YUYV scaling works just fine.

current value of MAX_DISPLAYS is 3, set this to 10 so that the 'displays'

Add support for DSI panels. DSI video mode panels will work directly. For

Currently, in omap_vout_isr(), if the panel type is DPI, and if we
get either VSYNC or VSYNC2 interrupts, we proceed ahead to set the
current buffers state to VIDEOBUF_DONE and prepare to display the
next frame in the queue.
On OMAP4, because we have 2 LCD managers, the panel type itself is not
sufficient to tell if we have received the correct irq, i.e, we shouldn't
proceed ahead if we get a VSYNC interrupt for LCD2 manager, or a VSYNC2
interrupt for LCD manager.
Fix this by correlating LCD manager to VSYNC interrupt and LCD2 manager
to VSYNC2 interrupt.

The commit 383e4f6987 makes reqbuf prevent
requesting a larger size buffer than what is allocated at kernel boot during
omap_vout_probe.
In omap_vout_buffer_setup callback API, the requested size is compared with
vout->buffer_size, this isn't correct as vout->buffer_size is later set to the
size requested in reqbuf. When the video device is opened the next time, this
check will prevent us to allocate a buffer which is larger than what we requested
the last time.
Don't use vout->buffer_size, always check with the parameters video1_bufsize
or video2_bufsize.

If "i" is 2 then when we call cx25821_video_mux() we'd end up going
past the end of the cx25821_boards[dev->board]->input[].

a bit hard to follow. And as Mauro points out the hard coded 2 is
not very helpful.
