* [media] cx23885: Revert "Check for slave nack on all transactions"Andy Walls2011-03-021-8/+0
| | | | | | | | | | | | | | | | | | This reverts commit 44835f197bf1e3f57464f23dfb239fef06cf89be. With the CX23885 hardware I2C master, checking for I2C slave ACK/NAK is not valid when the I2C_EXTEND or I2C_NOSTOP bits are set. Revert the commit that checks for I2C slave ACK/NAK on all transactions, so that XC5000 tuners work with the CX23885 again. Thanks go to Mark Zimmerman for reporting and bisecting this problem.

* V4L/DVB: FusionHDTV: Use quick reads for I2C IR device probingJean Delvare2010-06-011-1/+11
| | | | | | | | | | | | | | | | | | IR support on FusionHDTV cards is broken since kernel 2.6.31. One side effect of the switch to the standard binding model for IR I2C devices was to let i2c-core do the probing instead of the ir-kbd-i2c driver. There is a slight difference between the two probe methods: i2c-core uses 0-byte writes, while the ir-kbd-i2c was using 0-byte reads. As some IR I2C devices only support reads, the new probe method fails to detect them. For now, revert to letting the driver do the probe, using 0-byte reads. In the future, i2c-core will be extended to let callers of i2c_new_probed_device() provide a custom probing function. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: "Timothy D.

* V4L/DVB (12343): Stop defining I2C adapter IDs nobody usesJean Delvare2009-09-121-1/+0
| | | | | | | | | There is no point in defining I2C adapter IDs when no code is using them. As this field might go away in the future, stop using it when we don't need to. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB (11844): ir-kbd-i2c: Switch to the new-style device binding modelJean Delvare2009-06-161-0/+12
| | | | | | | | | | | | | | | | | | | 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>
* V4L/DVB (11297): cx23885: convert to v4l2_subdev.Hans Verkuil2009-03-301-63/+4
| | | | | | | | | | | | | | | Convert this driver to v4l2_subdev. Note that currently the only card with analog support in this driver is the HVR-1800. The analog tuner support in this driver is limited to what is needed for this board. When analog support is added for other cards, then the tuner load code will probably have to be expanded to take care of those boards. For example, there is currently no support for either radio tuners or tda9887 demods. I'd like to thank Steven Toth for testing this on his HVR-1800.
