Hi,

With the recent merger of [1] in the media-tree it is finally possible 
to resurrect the last pieces of the work that started in 2017 :-)

Patch 1/2 switches the default behavior of V4L2 async to use endpoint 
node matching instead of device node matching. This is made possible by 
[1] where the matching logic is already changed to allow for both 
possibilities.

Patch 2/2 removes the special case in R-Car CSI-2 driver which have 
always used endpoint node matching since it needed to work with ADV748x 
that register multiple sub-devices using endpoint nodes in the async 
framework.

With this small series the split between V4L2 drivers that use endpoint 
vs device node matching is finally closed \o/.
