Hans Verkuil 0ea6bc8d43 V4L/DVB (8523): v4l2-dev: remove unused type and type2 field from video_device
The type and type2 fields were unused and so could be removed.
Instead add a vfl_type field that contains the type of the video
device.

Hans Verkuil a399810ca6 V4L/DVB (8482): videodev: move all ioctl callbacks to a new v4l2_ioctl_ops struct
All ioctl callbacks are now stored in a new v4l2_ioctl_ops struct. Drivers fill in
a const struct v4l2_ioctl_ops and video_device just contains a const pointer to it.

This ensures a clean separation between the const ops struct and the non-const
video_device struct.

The functions in a header should not belong to another module. The prio functions

The ioctl functions belong to v4l2-ioctl.c, so create a new v4l2-ioctl.h header

Ricardo Cerqueira 66e6fbdf99 V4L/DVB (6833): Don't limit cx88 audio routing to blackbird boards
All cx2388 boards need the line-in audio to be routed from an external ADC
(refered to as "ADC mode" in the spec sheet), since the chip is uncapable
of dealing with baseband audio directly.
So... this patch enables normal mode when using the tuner (TV or Radio), and
enables ADC mode with any other source. It'll probably only work with boards
that have supported ADCs (such as the Wolfson wm9775)

Fix lack of audio on the MPEG-2 stream of wm8775 based blackbirds.

The wm8775 module initializes the audio input at "route 2", which doesn't
hold true for all boards. The HVR-1300, for example, uses route 1 for
tuner audio, and route 2 for baseband. So we must route the audio to the
proper input depending on what video input is being used.

Trent Piepho 5772f81326 V4L/DVB (6023): cx88: Clean up some ugly and inconsistent printk()s
Get rid of the "CORE" prefix from cx88 printks.  It was only used a few times,
and it makes it look like they're coming from the kernel core or something.

Fix the message, "TV tuner 60 at 0x1fe, Radio tuner -1 at 0x1fe", by adding a
"cx88[0]" prefix to be consistent, and to keep people who grep their dmesg
output for cx88 from missing it.  Get rid of the addresses, which are always
wrong.  The addresses are always set to -1, but because it's an unsigned 8-bit
value, the left shift converts it to the nonsense address 0x1fe.

In the cx8802 driver, some cut and pasted code prefixed lines with "CORE
cx88[0]:", which has been changed to "cx88[0]/2:" like the other printks from
the cx8802 driver.

Also fix some ugly printks in the cx8802 driver that used __FUNCTION__ for
KERN_INFO and KERN_ERR messages.

The changed printks in cx88-mpeg.c also needed lots of whitespace and
80-column fixes.

A bunch of misc changes in cx88-dvb.c and cx88-video.c to add message levels
or a consistent "cx88[?]/2" or "cx88[?]/0" prefix.

Trent Piepho 6a59d64c5c V4L/DVB (6021): cx88: Copy board information into card state
The cx88 driver state stored the ID of the board type in core->board.  Every
time the driver need to get some information about the board configuration, it
uses the board number as an index into board configuration array.

This patch changes it so that the board number is in core->boardnr, and
core->board is a copy of the board configuration information.  This allows
access to board information without the extra indirection.  e.g.
cx88_boards[core->board].mpeg becomes core->board.mpeg.

This has a number of advantages:
- The code is simpler to write.

- It compiles to be smaller and faster, without needing the extra array lookup
  to get at the board information.

- The cx88_boards array no longer needs to be exported to all cx88 modules.

- The boards array can be made const

- It should be possible to avoid keeping the (large) cx88_boards array around
  after the module is loaded.

- If module parameters or eeprom info override some board configuration
  setting, it's not necessary to modify the boards array, which would
  affect all boards of the same type.

Michael Krufky f24546a95a V4L/DVB (4757): Cx88: determine whether or not to use external adc
Some cx88-blackbird boards use an external adc, but not necessarily
for all inputs.  Thus, this needs to be configurable on the card level
for each input.
This patch allows for the usage of the external adc to be determined
by a bit setting in the cx88_input struct for cards based on the cx88
blackbird design.

Trent Piepho 902fc997ad V4L/DVB (4722): Cx88: Add support for VIDIOC_INT_[SR]_REGISTER ioctls
Add support for the advanced debugging ioctls, to allow access to the
cx88 registers from userspace.  Only i2c_id == 0 is supported, for access
to the cx88 adapter itself.  There isn't any support for access to I2C
clients of the adapter.  Most of them don't have R/W registers anyway,
and its necessary to use i2c-dev to talk to them from userspace.
