[PATCH] media: dt-bindings: media: renesas,vin: Add r8a779a0 support

[Niklas Söderlund]

Document support for the VIN module in the Renesas V3U (r8a779a0) SoC.
The V3U is different from other SoCs as it have 32 instead of 16 VIN
instances. The VIN instances are also connected to a new IP the R-Car
ISP Channel Selector.

    Only V3H has 16 VINs, no?

You are correct, most Gen3 have 8 and V3H have 16 and now V3U with 32.  
Will fix in a v2.
