devicetree names are normally expected to be real, aka no "x" as catchall. SoOK, I try to just use "rockchip,rk3228-gmac" to point to "rk322x_ops" which is the same structure in MAC driver,
I guess either just add compatibles for both the rk3228 and rk3229 which point
to the same structure in the driver. (So driver-side can stay as it is below,
just add a second compatible).
