However, before I queue this in renesas-devel for v5.10, I'd like to
have some clarification about the issue below.

"make dtbs W=1" says:

    arch/arm64/boot/dts/renesas/r8a774e1.dtsi:1562.12-1572.7: Warning

Referring to commit 5e53dbf4edb4d ("arm64: dts: renesas: r8a77990: Fix
VIN endpoint numbering") we definitely need endpoint numbering.
Probably the driver needs to be fixed to handle such cases.

On R-Car E3, the single endpoint is at address 2, so "make dtbs W=1"doesn't
complain. Here it is at address 0.

First the R-Car VIN driver makes decisions based on which endpoint is 
described, each endpoint 0-3 represents a different CSI-2 block on the 
other end (0: CSI20, 1: CSI21, 2: CSI40 and 3: CSI41).

Then how to handle the warning I'm not sure. I can only really see 2 
options.

1. Ignore the warning.
2. Remove #address-cells, #size-cells and reg properties from port@ if 
   the only endpoint described is endpoint@0.

I would prefers option 2. that is what we do in other cases (for example 
on Gen2 boards that only have a single parallel sensor in some early DTS 
files we don't have the ports node and just describe a single port with 
the same reasoning.

We are not at risk at someone describing a second CSI-2 bock as an 
overlay so I see no real harm in option 2. What are your thoughts Geert?  
You know more about DT then me.

That's my understanding, too.

Yeah, no overlay possible for on-SoC wiring ;-)

You have too much faith in me ;-)

AFAIK we don't get this warning for e.g. SPI buses, which can have a
single device at address 0, and #{address,size}-cells is mandatory
there. So endpoints (or SPI?) are treated special?

That is a good question, I don't know if either of those are treated
