This appears to be supported by hmwon but there's no binding for the
driver[1]. I'm hesitant to accept it and add more warnings to the
Aspeed devicetrees, but at the same time I'm sympathetic to leaving it
in.

Can you perhaps send a patch for
Documentation/devicetree/bindings/trivial-devices.yaml along with this
series?
