Hi,

> If your patch is applied, older revisions will stop working, right ?

correct, in the same way new revisions stopped working when that wrong fix was
applied.

> What about adding a new dtb like sun7i-a20-olinuxino-lime2-revk.dts ?

>From my POV proper fix for earlier HW revisions G/G1/G2 is introduction of
sun7i-a20-olinuxino-lime2-revG.dts with a proper `phy-mode` for RTL8211E PHY.

Cheers,
