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.
Other than the comment for the first patch this series looks good.
So once that's addressed I'll queue it up for 4.11.
