2009-08-10v4l: simplify v4l2_i2c_new_subdev and friendsHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Rewrite v4l2_i2c_new_subdev as a simplified version of v4l2_i2c_new_subdev_cfg and remove v4l2_i2c_new_probed_subdev and v4l2_i2c_new_probed_subdev_addr. This simplifies this API substantially. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2009-06-19Stop defining I2C adapter IDs nobody usesMauro Carvalho Chehab
From: Jean Delvare <khali@linux-fr.org> 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.

2009-05-27Building system: Restore compilation with kernels older than 2.6.29Mauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@redhat.com> Mostly due to ir-kdb-i2c, but also due to two new drivers, compilation with kernels older than 2.6.29 were broken. This quick and dirty changeset, generated semi-automatically, restaures backport to the subsystem by adding lots of #ifs. It is possible to write a much more small changeset that would restore backport without adding so many ifs, but, due to the lack of time, this will also solve it.

2009-05-13ivtv: Probe more I2C addresses for IR devicesMauro Carvalho Chehab

2009-05-13ir-kbd-i2c: Switch to the new-style device binding modelMauro Carvalho Chehab
From: Jean Delvare <khali@linux-fr.org> 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>

2009-04-01v4l2-common: add explicit v4l2_device pointer as first arg to ↵Hans Verkuil
new_(probed)_subdev From: Hans Verkuil <hverkuil@xs4all.nl> The functions v4l2_i2c_new_subdev and v4l2_i2c_new_probed_subdev relied on i2c_get_adapdata to return the v4l2_device. However, this is not always possible on embedded platforms. So modify the API to pass the v4l2_device pointer explicitly. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2009-03-30v4l2: use old-style i2c API for kernels < 2.6.26 instead of < 2.6.22Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Originally the intention was to switch to the new style i2c API starting with the introduction of the API in 2.6.22. However, the i2c_new_probed_device() function has a lethal bug that wasn't fixed until 2.6.25. Or more accurately, it was only fixed in the stable series of 2.6.25 and 2.6.26. Given the fact that the new i2c API also changed starting with 2.6.26 (the addition of i2c_device_id), it is easiest to switch APIs starting with 2.6.26. This patch updates all the legacy code accordingly. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2008-11-25fix boards for kernels with algo_controlMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@redhat.com> changeset 4ecae6da8244 removed algo_control from i2c drivers. However, on older kernels, a dummy function to implement algo_control is required, otherwise, an OOPS is generated. This patch adds a backport for all i2c drivers that defines an i2c_algorithm, except for cafe_ccic, since OLPC hardware only works for kernels newer than 2.6.19. Some of the backported drivers would need also extra changes to work with older kernels, as specified on v4l/versions.txt. Yet, I decided to add the backport for those drivers also, since the lack of algo_control doesn't generate any compilation error, but it is enough to break the driver. So, better to all for all boards than to allow compiling a kernel backported that just generates OOPS. Priority: normal Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-07-17saa7127: Make device detection optionalHans Verkuil
From: Jean Delvare <khali@linux-fr.org> The saa7127 driver supports all of SAA7126, SAA7127, SAA7128 and SAA1729 devices. Declare all these devices, so that board drivers can tell which device is present, instead of always relying on auto-detection (which needs to write to the chip, eek!). We still need the detection for ivtv, so a special device name "saa7127_auto" can be used when the caller doesn't know exactly which device is present.
