BS01DCMA is indeed a module, so the "board" wording in this series is wrong and I'll fix it in the next version. I'd still like to keep a single k3-bs01dcma.dts though. The module is only used in the RV2768, and that carrier is essentially just cabling to PCIe network cards. Those are found by enumeration and there's nothing else on it for the K3 to control, so a k3-bs01dcma-rv2768.dts would have nothing to describe. Does that work for you? --=20 Troy Mitchell --fa641b20d767eb6dfceae802e81e79246e3b4039a9ed52a8760cf69df47f Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iJcEABYKAD8WIQSL4Ay2cExaPXAQcU2YCe+A+TM0LwUCau1L4SEcdHJveS5taXRj aGVsbEBsaW51eC5zcGFjZW1pdC5jb20ACgkQmAnvgPkzNC8bHwEA/wJFXrKpYftH FB5kzcPBx6DamUD5F+4zMd1bZudAqVUBAKPNyObrwunkgozWj9HWqQMnkYJyk6XD Wmy765878T8H =dLV/ -----END PGP SIGNATURE----- --fa641b20d767eb6dfceae802e81e79246e3b4039a9ed52a8760cf69df47f-- --===============8312973095824652861== 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 --===============8312973095824652861==--
