I cannot replicate the build error on 5.4-RC3 at least for this
binding on V4 of the patch.  I get build error on other bindings.

$ make dt_binding_check ARCH=arm

I took out some of the logs to make it less chatty.  I don't know
anything about yaml or what the expectations are, so if there is a
test beyond 'make dt_binding_check' please let me know.

Thank you,
