ade48681f1 [media] v4l: Rename vb2_queue.timestamp_type as timestamp_flags
The timestamp_type field used to contain only the timestamp type. Soon it
will be used for timestamp source flags as well. Rename the field
accordingly.

[m.chehab@samsung.com: do the change also to drivers/staging/media and at s2255]

3299ba5c0b [media] v4l: vsp1: Supply frames to the DU continuously
When operating in DU output mode (deep pipeline to the DU through the
LIF), the VSP1 needs to constantly supply frames to the display. To
ensure reuse the last queued buffer instead of returning it to the user.

26a20eb09d [media] v4l: vsp1: Fix mutex double lock at streamon time
A mutex_lock() was left when the driver was converted to use the vb2
ioctl helpers, resulting in a deadlock at streamon time. Fix it.

26e0ca22c3 [media] v4l: Renesas R-Car VSP1 driver
The VSP1 is a video processing engine that includes a blender, scalers,
filters and statistics computation. Configurable data path routing logic
allows ordering the internal blocks in a flexible way.
Due to the configurable nature of the pipeline the driver implements the
media controller API and doesn't use the V4L2 mem-to-mem framework, even
though the device usually operates in memory to memory mode.
Only the read pixel formatters, up/down scalers, write pixel formatters
and LCDC interface are supported at this stage.
