Hans Verkuil dc02d50a6d V4L/DVB (5675): Move big PIO accesses from the interrupt handler to a workhandler
Sliced VBI transfers use PIO instead of DMA. This was done inside the
interrupt handler, but since PIO accesses are very slow this meant that
a lot of time was spent inside the interrupt handler. All PIO copies are
now moved to a workqueue. This should fix various issues with missing time
ticks and remote key hits.

Ian Armstrong 9e0df402e6 V4L/DVB (5438): Fix ivtv yuv threshold handling
Modifies automatic mode selection for yuv playback. Behaviour is now that
source video with a vertical resolution below that of the currently set
broadcast mode will be treated as progressive. Video with a vertical
resolution greater or equal to the current broadcast mode (up to 576 lines)
will be treated as interlaced.

The TV standard should be set AFTER the TV output is fully initialized.

Hans Verkuil fee73165ee V4L/DVB (5420): Initialize the inputs before registering the devices.
Once the devices have been registered anyone can start changing the inputs or
TV standard before they have been initialized by the driver. This leads to
cases were the input is changed in an udev rule, but after that rule is
triggered the tail-end of the ivtv driver initialization can override
that by selecting the tuner input.
The correct sequence is to first setup the input, initial frequency and TV
standard before finally registering the video devices. This prevents any
udev rules from being triggered prematurely.

Hans Verkuil f40a291684 V4L/DVB (5417): First unregister the driver, and then free the memory.
ivtv_remove which is called by pci_unregister_driver was still using
memory that was already freed. Ouch.

Hans Verkuil b6735ac24e V4L/DVB (5406): Add comment why the symbols are exported.
It is not immediately obvious why the ivtv symbols are exported
in ivtv-driver.c since both ivtv-fb and the IR-blaster module
are still out-of-tree, currently being ported to be in kernel.

Added a comment so people are aware of these issues.

Hans Verkuil 1a0adaf37c V4L/DVB (5345): ivtv driver for Conexant cx23416/cx23415 MPEG encoder/decoder
It took three core maintainers, over four years of work, eight new i2c
modules, eleven new V4L2 ioctls, three new DVB video ioctls, a Sliced
VBI API, a new MPEG encoder API, an enhanced DVB video MPEG decoding
API, major YUV/OSD contributions from Ian and John, web/wiki/svn/trac
support from Axel Thimm, (hardware) support from Hauppauge, support and
assistance from the v4l-dvb people and the many, many users of ivtv to
finally make it possible to merge this driver into the kernel.
Thank you all!
