You forgot to document the presence of the new optional "serdes-phy" PHY.

I think we should start rejecting most of bindings without DTS, because submitters really like to forget to make complete bindings. Having a DTS with such undocumented property gives a bit bigger chance it will get an attention. :( Best regards, Krzysztof

But for reviewers, this been a bit of chicken-egg problem. Bindings and driver changes have to go in first and via "subsystem" trees while DTS patches have to go via "arch" tree. So, they get posted separately. One may not see DTS patches (and thus user of the bindings) until bindings reach Torvalds' tree. So, user of bindings will only appear in the next kernel release cycle (at which time they do get flagged due to failing make dtbs_check but its bit late). Wondering how others are managing the same ? Regards Vignesh

Update bindings for TI K3 J721e SoC which contains 9 ports (8 external ports) CPSW9G module and add compatible for it. Changes made: - Add new compatible ti,j721e-cpswxg-nuss for CPSW9G. - Extend pattern properties for new compatible. - Change maximum number of CPSW ports to 8 for new compatible.
