2011-11-24[media] video: Drop undue references to i2c-algo-bitJean Delvare
There's one comment that has been copied from bttv to many other media/video drivers: /* init + register i2c algo-bit adapter */ Meanwhile, many drivers use hardware I2C implementations instead of relying on i2c-algo-bit, so this comment is misleading. Remove the reference to "algo-bit" from all drivers, to avoid any confusion. This is the best way to ensure that the comments won't go out of sync again. Anyone interested in the implementation details would rather look at the code itself. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-09-03[media] bt8xx: Use current logging stylesJoe Perches
This converts some messages that were emitted at KERN_INFO to KERN_DEBUG. All of these messages were guarded by bttv_debug tests. Add pr_fmt. Convert printks to pr_<level> Convert printks without KERN_<level> to appropriate pr_<level>. Removed embedded prefixes when pr_fmt was added. Whitespace cleanups when around other conversions. Macros coded with if statements should be do { if... } while (0) so the macros can be used in other if tests. Use ##__VA_ARGS__ for variadic macro as well. Coalesce format strings.

2010-02-19V4L/DVB: bttv: Move I2C IR initializationJean Delvare
Move I2C IR initialization from just after I2C bus setup to right before non-I2C IR initialization. This avoids the case where an I2C IR device is blocking audio support (at least the PV951 suffers from this). It is also more logical to group IR support together, regardless of the connectivity.

2009-12-16V4L/DVB (13597): bttv: add i2c addr for old WinTV card to IR probe listJarod Wilson
There are old bttv-driven Hauppauge WinTV series cards that have their IR part at i2c addr 0x71, which doesn't get considered in the new 2.6.31 i2c code. From a 2.6.29 kernel: lirc_i2c: chip 0x10005 found @ 0x71 (Hauppauge PVR150) Minor cosmetic glitch, the card in question isn't actually a PVR-150, its: 03:06.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) Subsystem: Hauppauge computer works Inc.

2009-09-12V4L/DVB (12343): Stop defining I2C adapter IDs nobody usesJean Delvare

2009-06-16V4L/DVB (11844): ir-kbd-i2c: Switch to the new-style device binding modelJean Delvare
Let card drivers probe for IR receiver devices and instantiate them if found. Ultimately it would be better if we could stop probing completely, but I suspect this won't be possible for all card types. There's certainly room for cleanups. For example, some drivers are sharing I2C adapter IDs, so they also had to share the list of I2C addresses being probed for an IR receiver. Now that each driver explicitly says which addresses should be probed, maybe some addresses can be dropped from some drivers. Also, the special cases in saa7134-i2c should probably be handled on a per-board basis. This would be more efficient and less risky than always probing extra addresses on all boards. I'll give it a try later. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2009-03-30V4L/DVB (11278): bttv: convert to v4l2_subdev since i2c autoprobing will ↵Hans Verkuil
disappear. Since i2c autoprobing will disappear bttv needs to be converted to use v4l2_subdev instead. Without autoprobing the autoload module option has become obsolete. A warning is generated if it is set, but it is otherwise ignored. Since the bttv card definitions are of questionable value a new option was introduced to allow the user to control which audio module is selected: msp3400, tda7432 or tvaudio (or none at all). By default bttv will use the card definitions and fallback on tvaudio as the last resort. If no audio device was found a warning is printed. The saa6588 RDS device is now also explicitly probed since it is no longer possible to autoprobe it. A new saa6588 module option was added to override the card definition since I suspect more cards have this device than one would guess from the card definitions. Note that the probe addresses of the i2c modules are hardcoded in this driver. Once all v4l drivers are converted to v4l2_subdev this will be cleaned up. Such data belongs in an i2c driver header.

2009-03-30V4L/DVB (10560): bttv: make tuner card info more consistentTrent Piepho
The bttv card database structure had a "tuner" field that was the input number of the tuner input or UNSET for no tuner. However, the only values it could ever be are 0 and UNSET. Having a tuner on an input other than 0 didn't work and was never used. There is also a "tuner_type" field that can be set to TUNER_ABSENT to indicate no tuner, which makes "tuner = UNSET" redundant. In many cases, tuner_type was set to UNSET when there was no tuner, which isn't quite correct. tuner_type == UNSET is supposed to mean the tuner type isn't yet known. So, I changed cards where "tuner == UNSET" to always have tuner_type of TUNER_ABSENT. At this point the tuner field is redundant, so I deleted it. I have the card setup code set the card's tuner_type (not the card type's tuner_type!) to TUNER_ABSENT if it hasn't yet been set at the end of the setup code. Various places that check if the card has a tuner will now look for this instead of checking the card type's "tuner" field. Also autoload the tuner module before issuing the TUNER_SET_TYPE_ADDR I2C client call instead of after issuing it. Overall, on ia32 this decreases compiled code size by about 24 bytes and reduces the data size by 640 bytes.

2008-07-20V4L/DVB (8047): bt8xx: i2c structure templates clean-upJean Delvare
Clean up the use of structure templates in bttv-i2c. For one thing, a real template is supposed to be read-only. And in some cases it's more efficient to initialize the few fields we need individually. This clean-up shrinks bttv-i2c.o by 29% (x86_64).

2006-09-26V4L/DVB (4609): Improved i2c performance on software bitbang algoritmMauro Carvalho Chehab
Software I2C were using a very conservative value of udelay=16, meaning about 20Kbps. According with Philips I2C datasheet, the i2c should answer well for times at the order of 4.7 us. So, using udelay=5 should work for all devices. After this patch, the speed should be close to 66,67 Kbps, with the current kernel software bitbang, with 30/60 duty cycle. Anyway, added a new parameter (i2c_udelay) that would allow using conservative values, if eventually a hardware doesn't support the datasheet values.

2006-03-24V4L/DVB (3577): Cleanup audio input handlingHans Verkuil
Cleanup audio input handling in bttv and tvaudio: - inputs were specified that were never used - mute was handled as a special input which led to confusing code - confusing naming made it difficult to see if the setting was for i2c or gpio. The old audiochip.h input names moved to tvaudio.h. Currently this is used both by tvaudio and msp3400 until the msp3400 implements the new msp3400-specific inputs. Detect in bttv the tvaudio and msp3400 i2c clients and use these client pointers to set the inputs directly instead of broadcasting the command. Removed AUDC_SET_INPUT. Now replaced by VIDIOC_S_AUDIO. This will be replaced again later by the new ROUTING commands. Removed VIDIOC_G_AUDIO implementations in i2c drivers: this command is a user level command and not to be used internally. It wasn't called at all anyway.
