2012-08-15[media] rename drivers/media/video as .../platformMauro Carvalho Chehab
The remaining drivers are mostly platform drivers. Name the dir to reflect it. It makes sense to latter break it into a few other dirs. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-04-26[media] marvell-cam: fix an ARM build errorJonathan Corbet
One of the OLPC changes lost a little in its translation to mainline, leading to build errors on the ARM architecture. Remove the offending line, and all will be well.

2012-03-19[media] mmp-camera: Don't power up the sensor on resumeJonathan Corbet
We still need to power up the controller to avoid unsightly self-immolation should something try to access its registers, but the sensor can stay powered down unless the camera was actually operating at suspend time. This gets rid of the camera LED flash on resume, fixing OLPC bug #11644. Signed-off-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-01-06[media] marvell-cam: Make suspend/resume work on MMP2Jonathan Corbet
Somehow I didn't ever quite get around to implementing suspend/resume on the MMP2 platform; this patch fixes that little oversight. A bit of core work was necessary to do the right thing in the s/g DMA case. Signed-off-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-09-18[media] mmp_camera: add MODULE_ALIASDaniel Drake
This enables module autoloading. Signed-off-by: Daniel Drake <dsd@laptop.org> Acked-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-07-27[media] marvell-cam: power down mmp camera on registration failureJonathan Corbet
If registration does not work, we don't want to leave the sensor powered on. Signed-off-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-07-27[media] marvell-cam: use S/G DMA by defaultJonathan Corbet
Scatter/gather DMA mode works nicely on this platform and is clearly the best way of doing things. Signed-off-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2011-07-27[media] marvell-cam: implement contiguous DMA operationJonathan Corbet
The core driver can now operate in either vmalloc or dma-contig modes; obviously the latter is preferable when it is supported. Default is currently vmalloc on all platforms; load the module with buffer_mode=1 for contiguous DMA mode.

2011-07-27[media] marvell-cam: Basic working MMP camera driverJonathan Corbet
Now we have a camera working over the marvell cam controller core. It works like the cafe driver and has all the same limitations, contiguous DMA only being one of them. But it's a start. Signed-off-by: Jonathan Corbet <corbet@lwn.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
