The idle-states binding documentation[1] mentions that the 'entry-method' property is required on 64-bit platforms and must be set to "psci".
Linux commit a13f18f59d26 ("Documentation: arm: Fix typo in the idle-states bindings examples") attempted to fix this earlier but clearly more is needed.
Linux docs: Documentation/devicetree/bindings/arm/idle-states.txt (see idle-states node)
