Trent Piepho f911eab66d V4L/DVB (11261): saa7146: Remove buffer type check from vidioc_g_parm
The v4l2-ioctl core now only allows buffer types for which the
corresponding ->vidioc_try_fmt_xxx() methods are defined to be used with
vidioc_(g|s)_parm.

The driver was only allowing VIDEO_CAPTURE buffers for g_parm, but since
the driver defines ->vidioc_try_fmt_vid_overlay() it will now allow
VIDEO_OVERLAY buffers as well.  This should be fine as the fields the
driver fills in, readbuffers and frame rate, aren't wrong for VIDEO_OVERLAY
buffers.

klaas de waal cf47d878e5 V4L/DVB (11236): tda827x: fix locking issues with DVB-C
Separate tuning table for DVB-C solves tuning problem at 388MHz

TechnoTrend C-1501 DVB-C card does not lock on 388MHz. I assume that
existing frequency table is valid for DVB-T.

This is suggested by the name of the table: tda827xa_dvbt.

Added a table for DVB-C with the name tda827xa_dvbc.

Added runtime selection of the DVB-C table when the tuner is type
FE_QAM.

This should leave the behaviour of this driver with with DVB_T tuners
unchanged. This modification is in file tda827x.c

The tda827x.c gives the following warning message when debug=1:

tda827x: tda827x_config not defined, cannot set LNA gain!

Solved this by adding a tda827x_config struct in budget-ci.c.

Mauro Carvalho Chehab 1398ae1fe6 V4L/DVB (11127): Kconfig: replace all occurrences of CUSTOMIZE to CUSTOMISE
There are several Kconfig items using CUSTOMIZE. Yet, most use the English
writing CUSTOMISE. This generates lots of trouble, because people sometimes type
the Kbuild item different.

Let's standardise every occurrence using the same syntax.

The changes were generated by this small shell script:

for i in `find linux -type f`; do sed s,CUSTOMIZE,CUSTOMISE,g $i >/tmp/a && mv /tmp/a $i; done

Devin Heitmueller ea2278633a V4L/DVB (11059): xc5000: fix bug for hybrid xc5000 devices with IF other than 5380
The xc5000 driver has a bug where the IF is always set to whatever the first
caller to dvb_attach() provides.  This fails when the device requires an IF
other than 5380 and the analog driver is loaded first through tuner-core
(which always supplies the hard-coded value of 5380).

Mauro Carvalho Chehab 68d5ce7021 V4L/DVB (10504): tda827x: Be sure that gate will be open/closed at the proper time
The gate control logic is broken: several routines just keep it open;
other rotines close it properly; there are even other routines that
assumes that it is open without really checking or opening it.

Instead of having to manually handle the gate control and having such
troubles, let a sub-routine take care of the gate, opening it before
i2c_transfer and closing it after that. This avoids leaving the gate
into a random state.

Mauro Carvalho Chehab ef88f2b563 V4L/DVB (10527): tuner: fix TUV1236D analog/digital setup
As reported by David Engel <david@istwok.net>, ATSC115 doesn't work
fine with mythtv. This software opens both analog and dvb interfaces of
saa7134.

What happens is that some tuner commands are going to the wrong place,
as shown at the logs:

Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: using tuner params #0 (ntsc)
Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: freq = 67.25 (1076), range = 0, config = 0xce, cb = 0x01
Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: Freq= 67.25 MHz, V_IF=45.75 MHz, Offset=0.00 MHz, div=1808
Feb 12 20:37:48 opus kernel: tuner 1-0061: tv freq set to 67.25
Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: using tuner params #0 (ntsc)
Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: freq = 67.25 (1076), range = 0, config = 0xce, cb = 0x01
Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: Freq= 67.25 MHz, V_IF=45.75 MHz, Offset=0.00 MHz, div=1808
Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: tv 0x07 0x10 0xce 0x01
Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: tv 0x07 0x10 0xce 0x01

This happens due to a hack at TUV1236D analog setup, where it replaces
tuner address, at 0x61 for 0x0a, in order to save a few memory bytes.

The code assumes that nobody else would try to access the tuner during
that setup, but the point is that there's no lock to protect such
access. So, this opens the possibility of race conditions to happen.

Instead of hacking tuner address, this patch uses a temporary var with
the proper tuner value to be used during the setup. This should save
the issue, although we should consider to write some analog/digital
lock at saa7134 driver.

Michael Krufky 6b55009e1d V4L/DVB (10170): tuner-simple: prevent possible OOPS caused by divide by zero error
A user reported the following OOPS with his pcHDTV HD5500 card, which
uses a cx88 PCI bridge with a LG-TDVS-H06xF frontend module, made up
of a TUA6034 tuner, TDA988x IF demod, and LG DT3303 ATSC/QAM demod.

Somehow, tuner-core gets loaded before the digital driver configures
the tuner, and tuner-core somehow incorrectly sets the tuner type to
LG NTSC (TAPE series) instead of LG TDVS-H06xF.  This tuner type does
not have the tuning stepsize defined, so an OOPS occurs during the
digital tune function.

We still dont know how the type gets set incorrectly in the first place.
The user has a tainted kernel with a binary nividia module, which COULD
have something to do with this, but it's hard to say for sure.

Nevertheless, to avoid this division by zero, we should check that
stepsize is defined.  If stepsize is not defined, print an error and
bail out on the tune request.

Hans Verkuil 069b747931 V4L/DVB (10138): v4l2-ioctl: change to long return type to match unlocked_ioctl.
Since internal to v4l2 the ioctl prototype is the same regardless of it
being called through .ioctl or .unlocked_ioctl, we need to convert it all
to the long return type of unlocked_ioctl.

Thanks to Jean-Francois Moine for posting an initial patch for this and
thus bringing it to our attention.

Hans Verkuil 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.

Devin Heitmueller d553cc958a V4L/DVB (9923): xc5000: remove init_fw option
The init_fw option was broken for the HVR-950q because we would call the reset
callback inside of dvb_attach() and the callback had not been setup yet.

Michael Krufky (who added the init_fw feature) says it's no longer required,
so just remove the option completely.

Thanks to user Zzeiss from #linuxtv chat for reporting the issue and
Michael Krufky <mkrufky@linuxtv.org> for proposing the fix.

Mauro Carvalho Chehab e278e746bc V4L/DVB (9913): tuner-xc2028: allow printing stack trace as debug on sleep code
tuner-xc3028 can be put to sleep to save power. However, if not properly
recovered from sleep, the device won't work. It is noticed that some
devices doesn't recover properly, so let's add a dump_stack() as a debug
option, to allow us to track when this happens.

Mauro Carvalho Chehab 9af0ef27a0 V4L/DVB (9775): tda8290: fix FM radio
tda8290 were using some random video standard for FM. This results on random
errors. Instead, program tda8290 in expert mode, using a configuration near the
one specified on NXP datasheet for tda8295 (available on their site).

Also, properly display that the device is on radio mode.

Mauro Carvalho Chehab 92d90f1a57 V4L/DVB (9774): tda827x: fix returned frequency
Probably due to a removed code, tda827x were doing some wrong calculus at the
returned frequency. I suspect that the original idea were to return the
programmed divisor converted into frequency again.

However, the current code is sometimes multiplying the programmed frequency by
62500, and, on other cases, like radio, it dividing it by 1000.

Instead of doing such math, let's just store the frequency value as requested by
the caller module.
