Hello,

This series adds bindings and support to rcar-vin for R-Car V4M by the 
means of adding a Gen4 family fallback compatible.

Previous versions of this series added V4M support like done for VIN 
since the first Gen3 device, by the use of only a single SoC specific 
compatible value. This was done as in Gen3 almost every new device 
differed from the others and a family fallback was not very useful.

For the two Gen4 devices with a video capture pipeline currently 
documented the VIN instances are very similar and a family fallback can 
be used. This however requires updating existing DTS files for V4H to 
add this new family fallback. This is done in a backward compatible way 
and the driver retains the compatible value for V4H.

See individual patches for changes since previous version.
