Two nodes in the tree carry that property regardless -- watchdog@a2c000 in hisi-x5hd2.dtsi and watchdog@8000 in mps2.dtsi. `make CHECK_DTBS=y`: watchdog@a2c000 (arm,sp805): Unevaluated properties are not allowed ('arm,primecell-periphid' was unexpected) Add the reference so the property becomes evaluable; both nodes then validate.
