* V4L/DVB (11846): ir-kbd-i2c: Don't assume all IR receivers are supportedJean Delvare2009-06-16
| | | | | | | | | | | | The code in ir_probe makes the dangerous assumption that all IR receivers are supported by the driver. The new i2c model makes it possible for bridge drivers to instantiate IR devices before they are supported, therefore the ir-kbd-i2c drivers must be made more robust to not spam the logs or even crash on unsupported IR devices. Simply, the driver will not bind to the unsupported devices. 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 Delvare2009-06-16
| | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | videobuf_dma_map/unmap Change kmalloc()/kfree() to vmalloc()/vfree() for sglist allocation during videobuf_dma_map() and videobuf_dma_unmap() High resolution sensors might require too many contiguous pages to be allocated for sglist by kmalloc() during videobuf_dma_map() (i.e. 256Kib for 8MP sensor). In such situations, kmalloc() could face some problem to find the required free memory. vmalloc() is a safer solution instead, as the allocated memory does not need to be contiguous.

* V4L/DVB (11837): uvcvideo: Start status polling on device openLaurent Pinchart2009-06-16
| | | | | | | | | | | | | | | | | | | | | Most UVC camera include an interrupt endpoint to report control value changes, video streaming errors and camera button events. The USB controller continuously polls the interrupt endpoint to retrieve such events. This prevents the device from being auto-suspended, and thus consumes power. Reporting video streaming errors don't make sense when the V4L2 device is closed. Control value changes are probably useless as well if nobody listens to the events, although caching will probably have to be completely disabled then. No polling is thus be required when /dev/videoX is not opened. To enable auto-suspend and save power do not poll the interrupt endpoint until the device is open. We lose the ability to detect button events if no application is using the camera. http://bugzilla.kernel.org/show_bug.cgi?id=11948 Signed-off-by: Laurent Pinchart <laurent.pinchart@skynet.be> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Note that for now the em2874 code isn't there, falling back to the 564 value, however this is not a problem since there are not any em2874 based devices in the current v4l-dvb tree).

* V4L/DVB (11807): cx88: remove xc5000 reset for Pinnacle 800iDevin Heitmueller2009-06-16
| | | | | | | | | | | | | | | | | | | | | | | According to the engineer at PCTV Systems, the xc5000 reset pin is supposed to be on GPIO12. However, despite three nights of effort, pulling that GPIO low didn't reset the xc5000. While pulling MO_SRST_IO low does reset the xc5000, this also resets in the s5h1409 being reset as well. This causes tuning to always fail since the internal state of the s5h1409 does not match the driver's state. Given that the only two conditions in which the driver performs a reset is during firmware load and powering down the chip, I am taking out the reset. We know that the chip is being reset when the cx88 comes online, and not being able to do power management for this board is better than not having any tuning at all. Problem discovered when implementing proper power management for the xc5000, which results in calls to the reset callback *after* s5h1409 is initialized.

This is consistent with the xc5000 specification, and improves tuning time by up to 500 ms on devices that such as the au0828 which do not properly implement i2c clock stretching (since the five register writes that occur for a tuning request often do not complete immediately but do complete far before 100ms has gone by).
