aecde8b53b V4L/DVB (10141): v4l2: debugging API changed to match against driver name instead of ID.
Since the i2c driver ID will be removed in the near future we have to
modify the v4l2 debugging API to use the driver name instead of driver ID.

Note that this API is not used in applications other than v4l2-dbg.cpp
as it is for debugging and testing only.

Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged
with a warning that it is deprecated and will be removed in 2.6.30.

bec43661b1 V4L/DVB (10135): v4l2: introduce v4l2_file_operations.
Introduce a struct v4l2_file_operations for v4l2 drivers.

Remove the unnecessary inode argument.

Move compat32 handling (and llseek) into the v4l2-dev core: this is now
handled in the v4l2 core and no longer in the drivers themselves.

Note that this changeset reverts an earlier patch that changed the return
type of__video_ioctl2 from int to long. This change will be reinstated
later in a much improved version.

This cleans-up the advise/acquire methods.

This has been tested on the hvr-1300/4000 and assumed to be
correct on the hvr-3000.

This update also fixes analogue tuning on the hvr-1300
when in blackbird mode.

a8782f669c V4L/DVB (9796): drivers/media/video/cx88/cx88-alsa.c: Adjust error-handling code
In the function cx88_audio_initdev, the value card has been created using
snd_card_new.  The other error handling code in this function frees the
value using snd_card_free.  I have thus changed the first error case to do
the same.  On the other hand, it may be that card is not sufficiently
initialized at this point to use snd_card_free, in which case something
else should be done to free the memory in the error case.

In the function snd_cx88_create the call kfree(chip) in one error case
looks suspicious, both because it is not done in the other error code, and
because chip points into the middle of the memory allocated by
snd_card_new, ie it is not itself associated with a separate kmalloc.
Therefore I have removed it.

The semantic match that finds the first problem is as follows:

8b21c1e90e V4L/DVB (9885): drivers/media Kconfig's: fix bugzilla #12204
When the tuner modules were moved to common/tuners, a separate customize
option were added for tuners. However, the automatic selection of the
tuners were still using the older option.

This causes that the automatic selection to fail, if DVB_FE_CUSTOMISE is
selected. Also, since those tuners are now under MEDIA_TUNER_CUSTOMIZE
menu, if you unset MEDIA_TUNER_CUSTOMIZE, you can't manually select the
tuners.

This patch fixes this error by replacing DVB_FE_CUSTOMISE by
MEDIA_TUNER_CUSTOMIZE on all places were a tuner is selected.

The patch were generated by this small script:

for i in `find drivers/media -name Kconfig`; do
  cat $i|perl -ne 's/(MEDIA_TUNER.*)DVB_FE_CUSTOMISE/\1MEDIA_TUNER_CUSTOMIZE/; print $_' >a
  mv a $i
done

Also, manually reordered the tuner entries.

0e8bac9791 V4L/DVB (9357): cx88-dvb: Fix Oops in case i2c bus failed to register
There already is an report at kernel bugzilla about this issue:
http://bugzilla.kernel.org/show_bug.cgi?id=9455

When enabling extra checks for the i2c-bus of cx88 based cards by
loading i2c_algo_bit with bit_test=1 this may trigger an oops
when loading cx88_dvb.

This is caused by the extra check code that detects that the
sda-line is stuck high and thus does not register the i2c-bus.

cx88-dvb however does not check if the i2c-bus is valid and just
uses core->i2c_adap to attach dvb frontend modules.
This leads to an oops at the first call to i2c_transfer:

$ modprobe i2c_algo_bit bit_test=1

c6330fb86f V4L/DVB (9327): v4l: use video_device.num instead of minor in video%d
The kernel number of a v4l2 node (e.g. videoX, radioX or vbiX) is now
independent of the minor number. So instead of using the minor field
of the video_device struct one has to use the num field: this always
contains the kernel number of the device node.

I forgot about this when I did the v4l2 core change, so this patch
converts all drivers that use it in one go. Luckily the change is
trivial.

This is a preliminary patch for later routing

This adds line-in support on the 2 cards mentioned.
It is also apparent that there is an initial open
fault for line-in when opening composite/s-video.
This will be fixed later.

It was also noticed that the bit-field for audio
routing which was 2 bits needs an increase as
the WM8775 for example, allows a value 4 bits
wide for it's audio mux.

59b1842da1 V4L/DVB (9227): MFE: Add multi-frontend mutual exclusion
This add frontend R/W mutual exclusion.
Prior to this point in time it was possible to open both
frontends simultaneously which an MFE card cannot support.

In order to stop this, a delayed open is performed which
has the following function:

-  Return EBUSY after a configurable amount of time
   if a frontend is unavailable due to the other being
   in use.

-  Only allow opening of a frontend if the kernel thread
   of the other has stopped.

This solution was chosen to allow switching between
frontends to work as seamlessly as possible. When both
frontends are actually opened simultaneously then one
will only open, but if quick switching is performed
between one of many then the new open will succeed in
a clean fashion rather than interrupting a kernel
thread.

8e739090d6 V4L/DVB (9225): MFE: Add configurable gate control
This adds a configurable (one per card) gate control option
for multi-frontend. Prior to this point gate control was
assumed to be on the primary frontend, this is a fault
when the gate to the analogue section is on the secondary
which is the default for both the HVR-3000 and HVR-4000
in MFE.

92abe9ee37 V4L/DVB (9223): MFE: Fix a number of bugs and some tidying up
A number of reference to videobuf_dvb_get_frontend used an invalid
index. This has been fixed.

The section for the HVR3000 in advise_acquire was redundant as
the same logic is used on the HVR4000. This has been removed
and both cards now use the same function.

A number of small errors and whitespace errors are also fixed.

363c35fc44 V4L/DVB (9222): S2API: Add Multiple-frontend on a single adapter support.
A detailed description from the original patches 2 years ago:

"The WinTV-HVR3000 has a single transport bus which is shared between
a DVB-T and DVB-S modulator. These patches build on the bus acquisition
cx88 work from a few weeks ago to add support for this.

So to applications the HVR3000 looks like this:
/dev/dvb/adapter0/fe0 (cx24123 DVB-S demod)
/dev/dvb/adapter0/fe1 (cx22702 DVB-T demod)

Additional boards continue as before, eg:
/dev/dvb/adapter1/fe0 (lgdt3302 ATSC demod)

The basic change is removing the single instance of the videobuf_dvb in
cx8802_dev and saa7134_dev(?) and replacing it with a list and some
supporting functions.

*NOTE* This branch was taken before v4l-dvb was closed for 2.6.19 so
two or three current cx88 patches appear to be reversed by this tree,
this will be cleaned up in the near future. The patches missing change
the mutex handing to core->lock, fix an enumeration problem."

It should be recognised that a number of people have been maintaining
this patchset. Significant levels of Kudos to everyone one involved,
including but not limited to:

Darron Broad
Fabio M. Di Nitto
Carlo Scarfoglio
Hans Werner

Without the work of these people, and countless others, my two year old
patches would of died on the Mercurial linuxtv.org vine a long time
ago.

TODO: Revise these patches a little further so that the need for
demux1 and dvr0 is optional, not mandatory on the HVR3000.

HISTORY (darron):
This is the last update to MFE prepared by Hans which is based
upon the `scratchpad' diff created by Carlo.
All MFE work prior to that point must be attributed to Fabio
who ported and maintained Steve's original patch up to that
time.

19c309e383 V4L/DVB (9135): cx88 Dvico FusionHDTV Pro
Well, one thing you encouraged me to do was re-test some of my cards
which contained the xc3028-zarlink combo.

Which led me to test a Dvico FusionHDTV Pro.

Almost a year ago, Chris Pascoe did a patch for this which can be found
at his ~pascoe/xc-test at Linuxtv.
This worked very well, however that was using his version of firmware.

Alas, someone attempted to use this and patch v4l-dvb, and messed it up.
So I've fixed it.
I enclose the patch against today's tree (containing your latest
tuner-xc2028.c patch).

The card now works very well, well with DVB-T anyway.

From the author:

"This fixes the problem where previously all client disconnects
put the analogue frontend into standby.

In the following example, the first command is succesfully
watching TV but the second command which returns EBUSY
detunes the receiver by entering it into the standby state.

tvtime -d /dev/video0 &
cat /dev/video0

3f6014fc77 V4L/DVB (9066): Pinnacle Hybrid PCTV Pro (pctv310c) DVB-T support
This patch against latest mercurial makes DVB-T working on Pinnacle
Hybrid PCTV Pro (pctv310c).

In cx88-dvb.c, a specific zl10353_config is created with the if2
inferred from the old comment in the currently used config. It is then
used for attach, and i2c_gate_ctrl is set to NULL.

The entry in cx88-cards.c is modified with GPIO gathered from windows
with regspy, and DVB enabled. The frontend is set to
XC3028_FE_ZARLINK456 to match the zl10353_config.

It is working great with the freeview channels I can receive.
