Hope to hear from you. Can someone just give me a yes/no question out of this thread? I'm not really immediately sure what's being asked of me. What exactly do you want to do with the opp-tables? "Split out" isn't super clear. Does that mean into board files? I am guessing it does, since you're saying that a particular board cannot support the 1.5 GHz mode. It's not unusual though to use delete node for unsupported opp-table entries, could that be done instead? FWIW, this weekend is -rc7, so I won't be applying any new material after that. --N4oiYSiiIoHTkUpd Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQRh246EGq/8RLhDjO14tDGHoIJi0gUCaRz80AAKCRB4tDGHoIJi 0s+FAQDMoM392mKet43CbIZa5XkVf0Nhavze4vBfQXc9CBkXkQEA7L47T/hTFt2g lgvgkf1AKUnNOrw/Pcnu6msIEVx0fAI= =RX+k -----END PGP SIGNATURE----- --N4oiYSiiIoHTkUpd-- --===============5593911614977254921== 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 --===============5593911614977254921==--
