Hi Conor,

Thanks for your feedback.

Currently it is. But that not always be true, I tried to outline this in 
to cover letter.

    The V4M capture pipeline is similar to the other Gen4 SoC supported
    upstream already V4H. Currently all futures supported for VIN on V4M are
    also supported by V4H and the driver code can be shared. But as done for
    other R-Car IP bindings a new dedicated binding for V4M is created.
    This have proved prudent in the past where quirks are found even within
    the same generation as more advance use-cases are enabled.
