Vlastimil Labsky 4d14c833c0 V4L/DVB (12439): cx88: add support for WinFast DTV2000H rev. J
I updated and simplyfied patch from Zbynek Hrabovsky for recent kernel.
It enables autodetection of card, sound in analog TV , sound in FM radio
and switching between antenna and cable RF input.  Radio tuner still
doesn't work, I don't even know how it works.  Some guys wrote me that FM
radio works with TV tuner used instead of radio part (symlink video0 ->
radio0).

hermann pitton 46058128ff V4L/DVB (12420): saa7134: fix the radio on Avermedia GO 007 FM
We have support for radio on saa7133/35/31e cards with tda8290/8275(a)
and 5.5MHz ceramic filter on the bridge chips since a while.

It was previously not tested, if this card supports it too, but the old
"ghost" radio with wrong filters doesn't work anymore.

Thanks go to Pham Thanh Nam and Laszlo Kustan for reporting it working

V4L2 API (chapter 1.5) states that:

	Drivers must implement all input ioctls when the device has one
	or more inputs, all output ioctls when the device has one or more outputs.
	When the device has any audio inputs or outputs the driver must set the
	V4L2_CAP_AUDIO flag in the struct v4l2_capability returned by the
	VIDIOC_QUERYCAP ioctl.

So, devices without audio input should return -EINVAL.

After the i2c subdev changes the ordering of initialization changed,
causing a total loss of previous GPIO settings and a loss of DTV.
The generic firmware loading routine has now changed to preserve
GPIO values if the device is cx23885 based (safety) and I've
moved the GPIO configuration from probe() into the cx23885 init
func which is a little clearer and fixes the bug.

Jan Nikitenko 43f8de7ac6 V4L/DVB (12342): af9015: avoid magically sized temporary buffer in eeprom_dump
Replace printing to magically sized temporary buffer with use
of KERN_CONT for continual printing of eeprom registers dump.

Since deb_info is defined as dprintk, which is conditionally defined
to printk without additional parameters, meaning that deb_info is equivalent
to direct printk (without adding KERN_ facility), we can use KERN_DEBUG and
KERN_CONT in there, eliminating the need for sprintf into temporary buffer
with not easily readable/magical size.

Though it's strange, that deb_info definition uses printk without KERN_
facility and callers don't use it either.

Remove the subdev_s_std() method from the GPIO subdev.  It appears it was
used in the past to effect the switch back from radio mode to tuner mode,
but it had a side effect that is improper and against the V4L2 spec, when
you were not in radio mode.  Whenever the video stanadrd was changed, the
GPIO audio mux was set back to the tuner audio input, even if you were set
to a Line In input.

Igor M. Liplianin d8300df9fb V4L/DVB (12332): Create card parameters array in SDMC DM1105 driver
Create card parameters array in SDMC DM1105 driver.
It is useful for cards with the same pci id, but different
tuners, lnb power control circuits, etc.

Laurent Pinchart bab6f66c08 V4L/DVB (12327): uvcvideo: Add PROBE_DEF quirk and enable it for the MT6227 device
At least one MT6227 model crashes when receiving a GET_DEF request on the
video probe control. As the various models can't be told apart based on the
descriptors, add a PROBE_DEF quirk to avoid sending the GET_DEF request and
enable the quirk for all models.

Lamarque Vieira Souza 76594c5315 V4L/DVB (12326): zr364xx: error message when buffer is too small and code cleanup
. added code to print an error message when buffer is too small to hold frame
data, that is better than just a hard crash. Tested using MAX_FRAME_SIZE =
50000, lots of error messages appeared in /var/log/messages but no crash.

. removed line "f->type = V4L2_BUF_TYPE_VIDEO_CAPTURE;" in
zr364xx_vidioc_try_fmt_vid_cap, it should not be there.

. changes to improve performance (or at least not hurt it): removed some
unneeded debug messages; added macro FULL_DEBUG to enable debug messages in
performance critical places, this macro is disabled by default; removed "if
(frm->lpvbits == NULL)..." in zr364xx_read_video_callback because after
analisying the source code I concluded it will always results to false, so it
is not needed.

. some small code reorganization.

Lamarque Vieira Souza 8c5f32ac2f V4L/DVB (12325): Implement changing resolution on the fly for zr364xx driver
This patch implements changing resolution in zr364xx_vidioc_s_fmt_vid_cap for
zr364xx driver. This version is synced with v4l-dvb as of 20/Jul/2009. Tested
with Creative PC-CAM 880.

OBS: I had to increase MAX_FRAME_SIZE to prevent a hard crash in my notebook
(caps lock blinking) when testing with mplayer, which automatically sets
resolution to the maximum (640x480). Maybe we should add code to auto-detect
frame size to prevent this kind of crash in the future.
