2013-02-05[media] omap3isp: Fix histogram regionsJohannes Schellen1-8/+8
This patch fixes a bug which causes all histogram regions to start in the top left corner of the image. The histogram region coordinates are 16 bit values which share a 32 bit register. The bug is due to the region end value assignments overwriting the region start values with zero.

2013-02-05[media] omap3isp: preview: Lower the crop marginsLaurent Pinchart1-19/+21
The preview engine includes filters that consume columns and lines as part of their operation, thus resulting in a cropped image. To allow turning those filters on/off during streaming without affecting the output image size, the driver adds additional cropping to make the total number of cropped columns and lines constant regardless of which filters are enabled. This process needlessly includes the CFA filter, as whether the filter is enabled only depends on the sink pad format, which can't change during streaming. Exclude the CFA filter from the preview engine margins.

2013-02-05[media] uvcvideo: Fix race of open and suspend in error caseOliver Neukum1-1/+1
Ming Lei reported: IMO, there is a minor fault in the error handling path of uvc_status_start() inside uvc_v4l2_open(), and the 'users' count should have been decreased before usb_autopm_put_interface(). In theory, a [URB resubmission] warning can be triggered when the device is opened just between usb_autopm_put_interface() and atomic_dec(&stream->dev->users). The fix is trivial.

2013-01-24[media] mb86a20s: calculate statistics at .read_status()Mauro Carvalho Chehab1-39/+224
Instead of providing separate callbacks to read the several FE stats properties, the better seems to use just one method that will: - Read lock status; - Read signal strength; - if locked, get TMCC data; - if locked, get DVB statistics. As the DVB frontend thread will call this read_status callback on every 3 seconds, and userspace can even call it earlier, all stats data and layers layout will be updated together if available, with is a good thing.

2013-01-24[media] dvb: the core logic to handle the DVBv5 QoS propertiesMauro Carvalho Chehab2-0/+45
Add the logic to poll, reset counters and report the QoS stats to the end user. The idea is that the core will periodically poll the frontend for the stats. The frontend may return -EBUSY, if the previous collect didn't finish, or it may fill the cached data. The value returned to the end user is always the cached data.
