2016-08-24[media] gspca: sonixj: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar1-9/+4
The workqueue "work_thread" is involved in updating the JPEG quality of the gspca_dev. It has a single work item(&sd->work) and hence doesn't require ordering. Also, it is not being used on a memory reclaim path. Hence, the singlethreaded workqueue has been replaced with the use of system_wq. System workqueues have been able to handle high level of concurrency for a long time now and hence it's not required to have a singlethreaded workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue created with create_singlethread_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantee unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference. Work item has been flushed in sd_stop0() to ensure that there are no pending tasks while disconnecting the driver.

2016-08-24[media] pvrusb2: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar2-17/+7
The workqueue "workqueue" is involved in polling the pvrusb2 hardware (pvr2_hdw). It has a single work item(&hdw->workpoll) and hence doesn't require ordering. Also, it is not being used on a memory reclaim path. Hence, the singlethreaded workqueue has been replaced with the use of system_wq. System workqueues have been able to handle high level of concurrency for a long time now and hence it's not required to have a singlethreaded workqueue just to gain concurrency.

2016-08-24[media] media: tw686x: Rework initial hardware configurationEzequiel Garcia1-58/+81
Currently, the hardware is not given a complete initial configuration. In order to fix this, this rather large commit reworks standard, frame format and input configuration. While at it, we introduce proper functions to configure each parameter, and as a result the code is a bit cleaner.

2016-08-24[media] v4l2-tpg-core: drop SYCC, use higher precision 601 conversion matrixHans Verkuil2-23/+21
The SYCC Y'CbCr encoding is identical to the 601 encoding. Since the SYCC define is about to be removed for use in the kernel we need to drop it in the TPG code as well. This patch also adds a 4th decimal to the 601 conversion matrix. That was specified by the sYCC spec and it makes sense to use this across the board.
