Andy Walls eefe1010a4 V4L/DVB (10759): cx18: Convert GPIO connected functions to act as v4l2_subdevices
Convert GPIO line functions, such a audio routing and device resets, to
v4l2_subdevices.  This essentially completes the conversion of cx18 to the
v4l2_device/v4l2_subdevice framework.  No regression testing has taken place as
of yet.  Also an ivtv legacy bug with GPIO mux routing and going to/from radio
mode was commented, but not fixed.

Andy Walls fa3e70360c V4L/DVB (10757): cx18, v4l2-chip-ident: Finish conversion of AV decoder core to v4l2_subdev
Added a new chip identifer to v4l2-chip-ident for the integrated A/V broadcast
decoder core internal to the CX23418.  Completed separation and encapsulation
of the A/V decoder core interface as a v4l2_subdevice.  The cx18 driver now
compiles and links again.

Andy Walls 812b1f9d54 V4L/DVB (10446): cx18: Finally get sliced VBI working - for 525 line 60 Hz systems at least
Sliced VBI, in the manner that ivtv implements it as a separate data stream,
now works for 525 line 60 Hz systems like NTSC-M.  It may work for 625 line
50 Hz systems, but I have more engineering work to do, to verify it is operating
properly.  Sliced data insertion into the MPEG PS should be working, but is
untested.

Andy Walls 466df46484 V4L/DVB (10445): cx18: Process Raw VBI on a whole frame basis; fix VBI buffer size
The cx23418 appears to send Raw VBI buffers with a PTS on a per frame
basis, not per field, so process Raw VBI on a whole frame basis and reduce
some complexity.  Fix VBI buffer size computation to handle a whole
frame of Raw VBI for a 625 line system, which is the worst case and will
work for 525 lines systems as well.

Andy Walls 01cbc214cf V4L/DVB (10444): cx18: Fix sliced VBI PTS and fix artifacts in last raw line of field
Fixed an endianess problem with the collection of the PTS from
the VBI buffer given to us by the encoder.  Also extrapolated the
last 12 bytes of the last line of each field, to remove artifacts
created by removing the first 12 bytes of each field for raw VBI.

Andy Walls 776fa86988 V4L/DVB (10440): cx18: Fix presentation timestamp (PTS) for VBI buffers
The old code from ivtv used a CX23415/6 PTS, which was simply left at 0 in the
cx18 driver.  Since the CX23418 gives us what I think is a PTS (or some other
90 kHz clock count) with each VBI buffer, this change has the cx18 driver use
that as a PTS.

Andy Walls af009cf635 V4L/DVB (9806): cx18: Enable raw VBI capture
A combined authorship patch from Hans Verkuil and Andy Walls.  Raw
VBI can now be captured but requires a video capture to be in progress as well.

Andy Walls dd073434b5 V4L/DVB (9805): cx18: Port fix for raw/sliced VBI mixup from ivtv and cx25840
This is a port of the fixes Hans Verkuil made for ivtv/cx25840:
The service_set field was used to determine whether raw or sliced VBI was
desired. This is incorrect since it is perfectly valid to select sliced VBI
with a service_set of 0.

Instead the driver should check on VIDIOC_S_FMT whether the type
field matches the raw or sliced VBI type.

Updated the cx18 driver accordingly, including an additional check in
cx18_start_v4l2_encode_stream() that didn't exist in ivtv.

Hans Verkuil 1c1e45d17b V4L/DVB (7786): cx18: new driver for the Conexant CX23418 MPEG encoder chip
Many thanks to Steve Toth from Hauppauge and Nattu Dakshinamurthy from
Conexant for their support. I am in particular thankful to Hauppauge
since without their help this driver would not exist. It should also
be noted that Steve did the work to get the DVB part up and running.
Thank you!
