As pointed by Marcin Slusarz <marcin.slusarz@gmail.com>, the warns happens because CONFIG_DVB_MAX_ADAPTERS depends on CONFIG_DVB_CORE, and there are valid configs where DVB_CORE is not selected. This causes such warnings, for every V4L and common drivers that may or may not be compiled with DVB support: drivers/media/dvb/dvb-core/dvbdev.h:36:2: warning: #warning invalid CONFIG_DVB_MAX_ADAPTERS value We can safely remove the warning.

2009-09-19V4L/DVB (13009): gspca - stv06xx-hdcs: Reduce exposure rangeJames Blanford
Due to rounding and clipping, exposure and gain settings do not map to unique register values. Rather than read the registers and report gain and exposure that may be different than the values that were set, just cache the latest values that were set and report them. Reduce exposure range from 0-65535 to 0-255 so libv4l's autogain doesn't take forever. Remove vestiges of driver signal processing that is now handled by libv4l.

http://linuxtv.org/wiki/index.php/Zolid_Hybrid_TV_Tuner test status analog (PAL-B): - Sometimes picture is noisy, but it becomes crystal clear after switching between channels. (happens for example at 687.25 Mhz) - On a lower frequency (511.25 Mhz) the picture is always sharp, but lacks colour. - No sound problems. - radio untested. Digital: - DVB-T/H stream reception works. - Would expect to see some more channels in the higher frequency region.

2009-09-19V4L/DVB (13000): add driver for 774 Friio White USB ISDB-T receiverAkihiro Tsukada
This patch adds driver for 774 Friio White, ISDB-T USB receiver Friio White is an USB 2.0 ISDB-T receiver. (http://www.friio.com/) The device has a GL861 chip and a Comtech JDVBT90502 canned tuner module. This driver ignores all the frontend_parameters except frequency, as ISDB-T shares the same parameter configuration across the country and thus the device can work like an intelligent one. As this device does not include a CAM nor hardware descrambling feature, the driver passes through scrambled TS streams. There is Friio Black, a variant for ISDB-S, which shares the same USB Vendor/Product ID with White, but it is not supported in this driver. They should be identified in the initialization sequence, but this feature is not tested. Signed-off-by: Akihiro Tsukada <tskd2@yahoo.co.jp> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Add a driver for Earthsoft PT1 Eearthsoft PT1 is a PCI card for Japanese broadcasting with two ISDB-S and ISDB-T demodulators. This card has neither MPEG decoder nor conditional access module onboard. It transmits only compressed and possibly encrypted MPEG data over the PCI bus, so you need an external software decoder and a decrypter to watch TV on your computer. This driver is originally developed by Tomoaki Ishikawa <tomy@users.sourceforge.jp> by reverse engineering.

2009-09-19V4L/DVB (12906c): V4L : vpif capture driver for DM6467Muralidharan Karicheri
This is the vpif capture bridge driver for DM6467. This video supports two video channels each having a tvp5147 device at the input. This allows simultaneous capture of NTSC/PAL video in each of this channel. Both MMAP and USERPTR io mechanism are supported. Currently buffer allocation happens at REQBUF ioctl request. Since USERPTR IO is supported, this is not an issue since user applications can allocate buffers and pass the user space address to the driver. Following are TODOs :- 1) Adding support for allocation of buffers at init 2) VBI/HBI data service This has incorporated comments received against version v0 of the patch series.

2009-09-19V4L/DVB (12725): v4l: warn when desired devnodenr is in use & add _no_warn ↵Hans Verkuil
function Warn when the desired device node number is already in use, except when the new video_register_device_no_warn function is called since in some use-cases that warning is not relevant. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2009-09-19V4L/DVB (12724): v4l2-dev: add simple wrapper functions around the devnode ↵Hans Verkuil
numbers There are some subtle differences in the way the devnode numbers are handled depending on whether the FIXED_MINOR_RANGES config option is set. Add some simple wrapper functions to handle that correctly. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2009-09-19V4L/DVB (12722): v4l2-dev: replace 'kernel number' by 'device node number'.Hans Verkuil
The term 'kernel number' is very vague, so replace it with the somewhat more descriptive term 'device node number'. In one place the local variable 'nr' was used to create the device node number of the new device name. This has been replaced with the vdev->num field to more clearly mark this as being the device node number and not the minor number.

2009-09-19V4L/DVB (12541): v4l: remove video_register_device_indexHans Verkuil
video_register_device_index is never actually called, instead the stream index number is always calculated automatically. This patch removes this function and simplifies the internal get_index function since that can now always just return the first free index.
