Subject: [PATCH 3/4] dt-bindings: arm: fix Rockchip rk3399-evb bindings

A test with the command below gives this error:

arch/arm64/boot/dts/rockchip/rk3399-evb.dt.yaml: /: compatible:
['rockchip,rk3399-evb', 'rockchip,rk3399', 'google,rk3399evb-rev2']
is not valid under any of the given schemas

Fix this error by adding 'google,rk3399evb-rev2' to the compatible
property in rockchip.yaml

make ARCH=arm64 dtbs_check
DT_SCHEMA_FILES=Documentation/devicetree/bindings/arm/rockchip.yaml

This looks wrong - the board can't reasonably be a *more* general match
than the SoC. If this is supposed to represent a specific variant of the
basic EVB design then it should come before "rockchip,rk3399-evb" (and
possibly be optional if other variants also exist).

Hi Robin,

When I look at the review process of rk3399-evb.dts
it is mentioned here:

The consensus in version 4 ends in what is shown in the dts file, so I
changed it in rockchip.yaml. Things from the past maybe can better be
explained by Heiko. Please advise if this patch needs to change and in
what file.

Kind regards,

Johan

Just get rid of the "google,rk3399evb-rev2" from the .dts please :-) .

(1) "rockchip,rk3399-evb", "rockchip,rk3399", "google,rk3399evb-rev2";
is just wrong for the reasons Robin explained, I guess that slipped
through review at the time.
(2) "google,rk3399evb-rev2" was a specific variant for Google I'm pretty
sure they'll have scraped all these boards directly after they had the
first actual rk3399-gru development devices

So I'm pretty sure the only rk3399-evbs in existence are the general ones.
