This is a V4L2 driver for TI OMAP1 SoC camera interface.
Both videobuf-dma versions are supported, contig and sg, selectable with a
module option. The former uses less processing power, but often fails to
allocate contignuous buffer memory. The latter is free of this problem, but
generates tens of DMA interrupts per frame. If contig memory allocation ever
fails, the driver falls back to sg automatically on next open, but still can
be switched back to contig manually. Both paths work stable for me, even
under heavy load, on my OMAP1510 based Amstrad Delta videophone, that is the
oldest, least powerfull OMAP1 implementation.The interface generally works in pass-through mode. Since input data byte
endianess can be swapped, it provides up to two v4l2 pixel formats per each of
several soc_mbus formats that have their swapped endian counterparts.Boards using this driver can provide it with the following platform data:
- if and what freqency clock is expected by an on-board camera sensor,
- what is the maximum pixel clock that should be accepted from the sensor,
- what is the polarity of the sensor provided pixel clock,
- if the interface GPIO line is connected to a sensor reset/powerdown input
and what is the input polarity.Created and tested against linux-2.6.36-rc5 on Amstrad Delta.

There are lots of checkpatch complains about:
ERROR: space prohibited after that open parenthesis '('
ERROR: space prohibited after that open square bracket '['
ERROR: space prohibited before that close parenthesis ')'
ERROR: space prohibited before that close square bracket ']'This script should fix all of them:

According with CodingStyle, drivers shouldn't use typedef, except on very
special cases. This is not the case of saa7164. So, convert all usecases
to struct/enum.After changing the saa7164-types.h, all we need to do is to run those scripts
to fix all occurrences of the bad types and double check/fix everything that
might be broken after the test (of course, I did a small script to generate those scripts).for i in drivers/media/video/saa7164/*.[ch]; do perl -ne "s/tmBusType_t/enum tmBusType/; print " \>a \&\& mv a tmBusType; done
