With recent dtc and W=1:

    ...salvator-x.dtb: Warning (graph_port): /soc/i2c@e66d8000/video-receiver@70/port@10: graph node unit address error, expected "a"
    ...salvator-x.dtb: Warning (graph_port): /soc/i2c@e66d8000/video-receiver@70/port@11: graph node unit address error, expected "b"

Unit addresses are always hexadecimal (without prefix), while the bases
of reg property values depend on their prefixes.

Fixes: 908001d778eba06e ("arm64: dts: renesas: salvator-common: Add ADV7482 support")

This looks a bit ugly with the different mappings;
If we must move to 'port@a', I think reg needs to be <0xa>, to avoid 
confusion. (but I personally prefer port@10, reg = <10> here)

I'd say yes. Thanks!

I'm happy to throw an

Acked-by: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com>

on the patch - but I had a pending question regarding the reg = <10> part.

Shouldn't the reg become hex "reg = <0xa>" to be consistent?

Either way - if there's precedent - take that route and I'm happy.

Consistency seems good to me, Geert?

Typically we use decimal for "small" and hex for "large" numbers.
So far this was mostly relevant for the size parts of "reg"
properties, as the address
parts are usually large (if part of the main memory space).

These are different, as they are not memory-mapped addresses.
If you want to see 0xa and 0xb in the reg properties, I can respin.

Gr{oetje,eeting}s,

I'll take this as is. We can decide how we want to address this,
in a consistent manner, without too many puns, later.
