Versioning aside, although that removes a large part of the motivation, the interface becomes quite nice: of_property_present(node, "riscv,isa-extension-zicbom") That also gives us the ability to define what supported vendor extensions actually mean in a dt-binding, which to me is a big win in terms of the aforementioned "wild west". --Hlry0DBSFS6pLHzF Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQRh246EGq/8RLhDjO14tDGHoIJi0gUCZF6WGgAKCRB4tDGHoIJi 0tSDAP0Uy884EZU8ra/A9tMZDF/H8y6sKV2j3Y/tSxG8um8DlwD/Zeg0BjmIdXDU se8CYwnqhCmDITzPbAm4T5pb4tKnyAA= =07sr -----END PGP SIGNATURE----- --Hlry0DBSFS6pLHzF--
