Prepare the groundwork for adding DT support for davinci VPIF drivers.
This series does some fixups/cleanups and then adds the DT binding and
DT compatible string matching for DT probing.
The controversial part from previous versions around async subdev
parsing, and specifically hard-coding the input/output routing of
subdevs, has been left out of this series. That part can be done as a
follow-on step after agreement has been reached on the path forward.
With this version, platforms can still use the VPIF capture/display
drivers, but must provide platform_data for the subdevs and subdev
routing.
Tested video capture to memory on da850-lcdk board using composite
input.
Changes since v5:
- locking fix: updated comment around lock variable
- binding doc: added example for
- added reviewed-by tags from Laurent (thanks!)
Changes since v4:
- dropped controversial async subdev parsing support. That can be
done as a follow-up step after the discussions have finalized on the
right approach.
- DT binding Acked by DT maintainer (Rob H.)
- reworked locking fix (suggested by Laurent)
Changes since v3:
- move to a single VPIF node, DT binding updated accordingly
- misc fixes/updates based on reviews from Sakari
Changes since v2:
- DT binding doc: fix example to use correct compatible
Changes since v1:
- more specific compatible strings, based on SoC: ti,da850-vpif*
- fix locking bug when unlocking over subdev s_stream
