* V4L/DVB (9662): uvcvideo: Fix printk badness when printing ioctl namesLaurent Pinchart2008-12-29
| | | | | | | | | Add a trailing newline character after calling v4l_printk_ioctl() to avoid messing the kernel log up and merge the uvc_v4l2_ioctl message with the ioctl name. Signed-off-by: Laurent Pinchart <laurent.pinchart@skynet.be> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB (9661): uvcvideo: Commit streaming parameters when enabling the ↵Laurent Pinchart2008-12-29
| | | | | | | | | | | | | | | | | | | | | | | video stream Sonix-based cameras seem to require the host to commit video streaming parameters before selecting the alternate endpoint. While most applications issue a VIDIOC_S_FMT ioctl before starting streaming, this is not required by the V4L2 specification. The problem has been noticed on Ubuntu 8.10 with applications using libv4l. The library blocks VIDIOC_S_FMT calls when the requested format is identical to the currently selected format. As the driver commits video streaming parameters when initialising the device, only the first run of a libv4l-enabled application would succeed. For the sake of completeness, experiment showed that the camera keeps sending 12 bytes isochronous packets (header only, no data) without toggling the FID bit if video streaming parameters haven't been committed before selecting the alternate endpoint.

* V4L/DVB (9653): em28xx: improve AC97 handlingMauro Carvalho Chehab2008-12-29
| | | | | | | | | | | | | | AC97 devices provide several input and outputs. However, before this patch, em28xx device weren't properly allowing the usage of ac97 possible combinations. Also, several input volumes were left untouched, instead of making sure that the volumes were set on mute state. This patch improves support for ac97 devices by allowing to use any inputs, and making sure that unused inputs are set on mute state. Yet, some work is still needed to select the AC97 output.

* V4L/DVB (9652): em28xx: merge AC97 vendor id's into a single varMauro Carvalho Chehab2008-12-29
| | | | | | | | This makes easier to identify vendor ID, since AC97 vendors are generally identified by 3 bytes. The remaining byte is used by the vendor to identify its devices. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | This patch properly implements audio handling on em28xx. Before this patch, it was assumed that every device has an Empia 202 audio chip. However, this is not true.

* V4L/DVB (9607): em28xx: Properly implement poll support for IR'sMauro Carvalho Chehab2008-12-29
| | | | | | | | | | | | | | The first em28xx were based on i2c IR's. However, some newer designs are coming with a polling-based IR. Those are done by reading a register set at em28xx. This patch adds core polling support for those devices. Later patches will add support for some device-specific IR's. This patch adds the same basic IR polling code used by bttv, cx88 and saa7134, and shares the common getkey masks defined at ir-common. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | Empia switched to a 16-bit addressable eeprom in newer devices. While we could certainly write a routine to read the eeprom, there is nothing of use in there that cannot be accessed through registers, and there is the risk that we could corrupt the eeprom (since a 16-bit read call is interpreted as a write call by 8-bit eeproms). So just be safe and bail out of the function. Thanks for Ray Lu from Empia for providing the em2874 datasheet.
