Hrm, technically the driver will currently only match on :
  "renesas,rcar-gen3-hdmi"

But I see how the '-dw-' has probably snuck in from other devices, and
is inappropriate.

Perhaps this should be more clear that it matches on the generic compatible:
	renesas,rcar-gen3-hdmi

(or a combination of both?)

But if the generic isn't required, then this patch alone does fix what I
would call an error, so ...

We could always make this more clear when converting to YAML.

You're right, the generic compatible string should be required. I'll
update this patch accordingly, and will address the bindings as part of
the conversion to YAML.

Proposed new commit:

commit cc487cbb06d841ca76efade63201a41bd04f6015
Author: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>
Date:   Tue Sep 8 09:34:11 2020 +0900

    dt-bindings: display: renesas: dw-hdmi: Tidyup example compatible

    The DT example erronously uses the "renesas,r8a7795-dw-hdmi", when the
    correct value is "renesas,r8a7795-hdmi". It is furthermore missing the
    generic "renesas,rcar-gen3-hdmi" compatible string. Fix it.
