* V4L/DVB (11624): cx18: Toggle the AI1 mux when changing the ↵Andy Walls2009-06-161-6/+38
| | | | | | | | | | | | | | | | CX18_AUDIO_ENABLE register Toggle the AI1 mux when changing the CX18_AUDIO_ENABLE register. It's hard to reliably tell when we have written to this register successfully unless we change some bits we know we can read back. The AI mux bits always read back what we wrote to them, so force them to toggle whenever we have to write to the register, so we can tell we wrote to the register successfully. This change was prompted by users experiencing broadcast audio decoding problems after the cx18 module loads for the first time.

* V4L/DVB (11494): cx18: Send correct input routing value to external audio ↵Andy Walls2009-04-291-1/+1
| | | | | | | | | | | multiplexers A late v4l2_subdev framework change accidentally sent the audio input routing value to the external multiplexer, instead of the muxer input routing value to the external multiplexer. This change corrects that error. Signed-off-by: Andy Walls <awalls@radix.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB (11380): v4l2-subdev: change s_routing prototypeHans Verkuil2009-04-061-6/+3
| | | | | | | | | It is no longer needed to use a struct pointer as argument, since v4l2_subdev doesn't require that ioctl-like approach anymore. Instead just pass the input, output and config (new!) arguments directly. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* V4L/DVB (10758): cx18: Convert I2C devices to v4l2_subdevicesAndy Walls2009-03-301-37/+13
| | | | | | | | | This is a major perturbation to cx18 I2C device handling to convert it to the v4l2_device/subdeivce framework. This change breaks GPIO audio multiplexer control for the time being. It will be fixed in a coming change. Signed-off-by: Andy Walls <awalls@radix.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB (10434): cx18: Smarter verification of CX18_AUDIO_ENABLE register writesAndy Walls2009-03-301-2/+1
| | | | | | | | | The CX18_AUDIO_ENABLE register usually never reads back what was just written under normal circumstances. Perform better checking that a write went to the register as expected with a specification of what bits to verify.

* V4L/DVB (7786): cx18: new driver for the Conexant CX23418 MPEG encoder chipHans Verkuil2008-04-291-0/+73
Many thanks to Steve Toth from Hauppauge and Nattu Dakshinamurthy from Conexant for their support. I am in particular thankful to Hauppauge since without their help this driver would not exist. It should also be noted that Steve did the work to get the DVB part up and running. Thank you!
