This is V3 of the physically contiguous videobuf queues patch. Useful for hardware such as the SuperH Mobile CEU which doesn't support scatter gatter bus mastering. Since it may be difficult to allocate large chunks of physically contiguous memory after some uptime due to fragmentation, this code allocates memory using dma_alloc_coherent(). Architectures supporting dma_declare_coherent_memory() can easily avoid fragmentation issues by using dma_declare_coherent_memory() to force dma_alloc_coherent() to allocate from a certain pre-allocated memory area. Changes since V2 - use dma_handle for physical address - use "scatter gather" instead of "scatter gatter" Changes since V1: - use dev_err() instead of pr_err() - remember size in struct videobuf_dma_contig_memory - keep struct videobuf_dma_contig_memory in .c file - let videobuf_to_dma_contig() return dma_addr_t - implement __videobuf_sync() - return statements, white space and other minor fixes Signed-off-by:

This patch moves the spinlock handling from soc_camera.c to the actual camera host driver. The spinlock_alloc/free callbacks are replaced with code in init_videobuf(). So far all camera host drivers implement their own spinlock_alloc/free methods anyway, and videobuf_queue_core_init() BUGs on a NULL spinlock argument, so, new camera host drivers will not forget to provide a spinlock when initialising their videobuf queues.

Makes SoC camera videobuf independent. Includes all necessary changes for PXA camera driver (currently the only driver using soc_camera in the mainline). These changes are important for the future soc_camera based drivers. Signed-off-by:

cx18: added in cx18_ir_reset_gpio function for lirc_pvr150 like module. Also added the ability to reset the IR chip via ioctl like ivtv. This needs the mutex to protect gpio_dir and gpio_val in struct cx18 as gpio changes can come from a few different asynchronous sources now. Signed-off-by:

For VIDIOC_G_FMT/VIDIOC_TRY_FMT, the V4L2 API spec states: "Drivers should not return an error code unless the input is ambiguous" "Very simple, inflexible devices may even ignore all input and always return the default parameters." "When the requested buffer type is not supported drivers return an EINVAL error code." i.e. returning errors for unsupported fields is bad, and it's ok to unconditionally overwrite user-requested settings This patch makes ov7670 meet that behaviour, and brings it in line with other drivers e.g. stk-webcam. It also fixes compatibility with (unpatched) gstreamer. Signed-off-by:
