Hi @Andrew, I just upstreamed the patch
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/Documentation/devicetree/bindings/trivial-devices.yaml?id=3d973b98d2744cfced1f06167c83e2cc2d7b63d5
to linux-next branch, I think we also need to pick it up to
https://github.com/openbmc/linux/tree/dev-6.6, which will help pass the
"onnn,adt7462" compatible warning log from the dt_binding_check tool.
