Surely other boards have pins for > expansion cards. It's totally not just these two - there's been a flurry of similar patches recently. The RPi stuff got it - I think I Acked that one from the DT side while Rob and Krzysztof were out of office, partially on the basis that the Nvidia stuff had it (and IIRC Renesas). Since then there's been a couple other ones that got the same treatment, including 32-bit ARM Microchip stuff. I've been avoiding doing it for the RISC-V Microchip to see if Rob decides that what I Acked was a problem. It seems generally helpful, so I've been a little suspicious as to why it was not done already... --6yhNlt3iEraEviEJ Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQRh246EGq/8RLhDjO14tDGHoIJi0gUCZK7TewAKCRB4tDGHoIJi 0nFMAP4z0kyCJ9bo9NdV1fEaEaWPTMD3SWgash90+nz8lEEzgAD/Yp90Wvv/78Va 3OsBKHedafWudPyyGbZWiAK2dfxTmwQ= =13KF -----END PGP SIGNATURE----- --6yhNlt3iEraEviEJ-- --===============7174034676134134922== 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 --===============7174034676134134922==--
