Proposed new commit:
commit cc487cbb06d841ca76efade63201a41bd04f6015

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.
