This patch provides a V4L2 SoC Camera driver for OV6650 camera sensor, found on OMAP1 SoC based Amstrad Delta videophone. Since I have no experience with camera sensors, and the sensor documentation I was able to find was not very comprehensive, I left most settings at their default (reset) values, except for: - those required for proper mediabus parameters and picture geometry and format setup, - those used by controls. Resulting picture quality may be far from perfect, but better than nothing. In order to be able to get / set the sensor frame rate from userspace, I decided to provide two not yet SoC camera supported operations, g_parm and s_parm. These can be used after applying patch 4/6 from this series, "SoC Camera: add support for g_parm / s_parm operations". Created and tested against linux-2.6.36-rc5 on Amstrad Delta. Signed-off-by:

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. Signed-off-by:

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];
