This is V3 of the SuperH Mobile CEU soc_camera driver.
The CEU hardware block is configured in a transparent data fetch
mode, frames are captured from the attached camera and written to
physically contiguous memory buffers provided by the newly added
videobuf-dma-contig queue. Tested on sh7722 and sh7723 processors.
Changes since V2:
- remove SUPERH Kconfig dependency
- move sh_mobile_ceu.h to include/media
- add board callback support with enable_camera()/disable_camera()
- add support for declare_coherent_memory
- rework video memory limit
- more verbose error messages
Changes since V1:
- fixed the CEU driver to work with the newly updated patches

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

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.

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.
