Guennadi Liakhovetski a81fb9b223 V4L/DVB: V4L: SuperH Video Output Unit (VOU) driver
A number of SuperH Mobile SoCs, including sh7724, include a Video Output Unit.
This patch adds a video (V4L2) output driver for it. The driver uses v4l2-subdev
and mediabus APIs to interface to TV encoders.

Guennadi Liakhovetski e622681d12 V4L/DVB: sh_mobile_ceu_camera.c: preserve output window on VIDIOC_S_CROP
Current version of sh_mobile_ceu_camera.c interprets the V4L2 API specification
of the VIDIOC_S_CROP ioctl as "change input (for capture devices) area,
preserve scaling factors, therefore change output window," whereas a more
intuitive interpretation of the API is "change input area, preserve output
window." Switch sh_mobile_ceu_camera.c to use this interpretation.

Hans Verkuil 730947bc14 V4L/DVB: vivi: clean up and a major overhaul
- Clean up the code
- Use the kernel's built-in vga8x16 font instead of our own.
- Drop exclusive open: now multiple users can open the device as per the V4L2 spec.
- Move the format description to the vivi device instead of keeping it in the file
  handle. Again as per the spec.
- Streamline and simplify the drawing code. It is now easy to add text on top of
  the colorbar pattern.
- Upgrade the max resolution to 1920x1200.

drivers/media/video/videobuf-dma-sg.c: In function ‘__videobuf_mmap_mapper’:
drivers/media/video/videobuf-dma-sg.c:557: warning: ‘size’ may be used uninitialized in this function

The condition where size is floating should never happen, due to the paranoia check,
but a future change at the logic might break it. So, let's just set size to zero and
use it for the paranoia check.

Hans Verkuil 0b62b73778 V4L/DVB: v4l videobuf: add videobuf_buffer *buf as argument to mmap_mapper
mmap_mapper should operate on a buffer, not on a complete queue. So let
the videobuf-core find the correct buffer instead of duplicating that
code in each mmap_mapper implementation.

The dma-sg implementation has backwards compatibility code for handling
the V4L1_COMPAT layer. This code is now under the v4L1_COMPAT config option.

The video_copy_to_user and copy_stream ops are almost identical for all
videobuf memtype variants. All that is needed is to use the new vaddr
op and these functions can be moved into the core, ensuring we have just
one single implementation instead of three.

Klaus Schmidinger b187913c77 V4L/DVB: Add FE_CAN_PSK_8 to allow apps to identify PSK_8 capable DVB devices
The enum fe_caps provides flags that allow an application to detect
whether a device is capable of handling various modulation types etc.
A flag for detecting PSK_8, however, is missing.
This patch adds the flag FE_CAN_PSK_8 to frontend.h and implements
it for the gp8psk-fe.c and cx24116.c driver (apparently the only ones
with PSK_8). Only the gp8psk-fe.c has been explicitly tested, though.

other cards.

I didn't set configure a tuner by a tuner model because this tuner can
