Since i2c autoprobing is no longer supported by v4l2 we need to make sure
that the i2c modules are linked before the v4l2 modules. The v4l2 modules
now rely on the presence of the i2c modules, so these must have initialized
themselves before the v4l2 modules.
The exception is the ir-kbd-i2c module, which is the only one still using
autoprobing. This one should be loaded at the end of the v4l2 module. Loading
it earlier actually causes problems with tveeprom. Once ir-kbd-i2c is no
longer autoprobing, then it has to move up as well.
This is only an issue when everything is compiled into the kernel.
Thanks to Marcus Swoboda for reporting this and Udo Steinberg for testing
this patch.

Add ADV7343 I2C based video encoder driver. This follows the
v4l2-subdev framework. This driver has been tested on TI DM646x EVM. It
has been tested for Composite and Component outputs.
Updates as per review by Mauro Chehab, added support for more standards
supported by the encoder. Also adding the missed out signed-offs.Tested
only NTSC and PAL standards.

With the transition of soc-camera to become a platform driver and to the

of a static build clients (i2c) drivers have to be available when host

The device encodes component video up to 1080i to a MPEG-TS stream with

(up to 5.1) audio over optical SPDIF without reencoding.
Firmware upgrade is unimplemeted but rather unimportant since
the firmware sits on a flash chip.

videodev.c became top-heavy so all the ioctl processing has been split off
into v4l2-ioctl.c. This means videodev.c is back to its original purpose:
creating and registering v4l devices.
Since videodev.c and v4l2-ioctl.c should still remain one module (as least
for now) I also had to rename videodev.c to v4l2-dev.c to prevent a
circular dependency when building a videodev.ko module. This is not a bad
thing, since the source and header now have the same name. And the v4l2-
prefix is useful to see which sources are generic v4l2 support code.

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

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 driver provides an interface between platform-specific camera
busses and camera devices. It should be used if the camera is connected
not over a "proper" bus like PCI or USB, but over a special bus, like,
for example, the Quick Capture interface on PXA270 SoCs. Later it should
also be used for i.MX31 SoCs from Freescale. It can handle multiple
cameras and / or multiple busses, which can be used, e.g., in

tuner-types is needed for tuner-simple, and does not need to be bound
to tuner-core. Any caller of tuner-simple, including tuner-core, needs
to pass a structure from tuner-types into tuner-simple at attach-time.
