There was nothing in the original series (AFAIR) that actually uses the properties. Including it in the Linux DTS just makes life easier, since the dts could also be used in OpenSBI? > It looks like you've tried to restart the discussion on the DT list [1] > so I hope that the DT maintainers will give their perspective.

I already gave feedback about it which has been ignored. --CxXu613LXMe5kC+W Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQRh246EGq/8RLhDjO14tDGHoIJi0gUCZNZ0DQAKCRB4tDGHoIJi 0ulpAQD+MhyrwIMZu/OHV7kmlJ8+cHk6ntWVt/wF02p8DWTHXwD/ZIRNDQPRWB+A bqkAwKwfa3oPmtvhr01lQVk/iLOhTwQ= =cDLk -----END PGP SIGNATURE----- --CxXu613LXMe5kC+W-- --===============5126757954805124964== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ linux-riscv mailing list linux-riscv@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-riscv --===============5126757954805124964==--
