V4L/DVB (6247): Fix bug #8689: Fixes IR stop/start during suspend/resume

IR workqueue should be disabled during suspend. This avoids some troubles, like
the one reported on bug #8689:

"The Hauppauge HVR 1100 ir-remote control does not work after resume from
suspend to ram or disk."

This patch disables IR before suspending, re-enabling it after resume.

Thanks to Peter Poklop <Peter.Poklop@gmx.at> for reporting it and helping with
the fix.

Fixes use of parport_write_control() to match the newer interface that

This eliminates the following error message and restores the original

Also increases threshold in qc_detect() from 300 to 400, as my camera often

V4L/DVB (6235): cafe_ccic: default to allocating DMA buffers at probe time

By default, we allocate DMA buffers when actually reading from the video
capture device.  On a system with 128MB or 256MB of ram, it's very easy
for that memory to quickly become fragmented.  We've had users report
having 30+MB of memory free, but the cafe_ccic driver is still unable to
allocate DMA buffers.

Our workaround has been to make use of the 'alloc_bufs_at_load' parameter
to allocate DMA buffers during device probing.  This patch makes DMA
buffer allocation happen during device probe by default, and changes
the parameter to 'alloc_bufs_at_read'.  The camera hardware is there,
if the cafe_ccic driver is enabled/loaded it should do its best to ensure
that the camera is actually usable; delaying DMA buffer allocation
saves an insignicant amount of memory, and causes the driver to be much
less useful.

V4L/DVB (6210): pvrusb2: Do a far better job at setting the default initial video standard

The v4l tveeprom logic tells us what video standards are supported by
the hardware, however it doesn't directly tell us what should be the
preferred initial standard.  For example "NTSC/NTSC-J" devices are
reported by tveeprom as support NTSC-M and PAL-M, and while that might
be true, in the vast majority of cases NTSC-M is really what the user
is going to want.  However the driver previously just arbitrarily
picked the "lowest numbered" standard as the initial default, which in
that case would have been PAL-M.  (And making matters more confusing -
this only caused real problems on 24xxx devices because the saa7115 on
29xxx seems to autodetect the right answer anyway.)  This change
implements an algorithm that uses the set of "supported" standards as
a hint to decide on the initial standard.  This algorithm ONLY comes
into play if the driver isn't specifically told what to do; said
another way - the user can always still change the standard via the
sysfs interface, via the usual V4L methods, or even specified as a
module parameter.  The idea here is only to pick a better starting
point if the user (or app) doesn't otherwise do something to set the
standard; otherwise this change has no real impact.

So the channel with the most attenuation has a range of 0 to -126 dB, while
the other channel only has a range of 0 to -63 dB.  ALSA volume controls don't
appear to support this concept.  I just limited the range to 0 to -63 total.
Once you get to -63 dB, you're already at silence, so additional attenuation

V4L/DVB (6167): cx23885: Changed PCI quirks to after bridge detech

either the tuner driver for status, or the demodulator status when the

V4L/DVB (6127): tuner: kill i2c_client interface to tuner sub-drivers

To ease the conversion of the analog tuner sub-drivers into dvb_frontend
style tuner modules, we must remove the i2c_client interface.

dvb_frontend style tuner modules use i2c_transfer directly on the i2c_adapter.

This change only alters the interface between tuner.ko and the tuner
sub-drivers. The v4l2 / i2c_client interface to tuner.ko remains intact.

This patch adds inline functions tuner_i2c_xfer_send, and tuner_i2c_xfer_recv,
to replace i2c_master_send and i2c_master_recv inside the tuner sub-drivers.

V4L/DVB (6126): tuner: add warning for obsolete i2c address range 0x64 thru 0x6f

The tuner module has a rather aggressive range of possible i2c addresses.

As per the specs available, it appears as if there are no 4-byte tuners that
actually use i2c addresses in the range 0x64 thru 0x6f, yet, tuner-core claims
the address range 0x60 thru 0x6f.

Allowing tuner.ko to probe these addresses can cause potential damage to
certain IR receivers, RTC chips or any other IC's that might otherwise reside
on the i2c bus using one of these addresses.

The plan is to remove these i2c addresses from the i2c address range of the
tuner module. If any devices are discovered that actually do have tuners at
one of these addresses, the newer i2c probing methods will be used to handle
those cases.

In order to collect this information and avoid any potential regressions,
the following warning has been added upon successful detection of a tuner
using an i2c address in the range 0x64 thru 0x6f:

====================== WARNING! ======================
Support for tuners in i2c address range 0x64 thru 0x6f
will soon be dropped. This message indicates that your
hardware has a {tuner name} tuner at i2c address {addr}.
To ensure continued support for your device, please
send a copy of this message, along with full dmesg
output to v4l-dvb-maintainer@linuxtv.org
Please use subject line: "obsolete tuner i2c address."
