From: Alexander Sverdlin <alexander.sverdlin@siemens.com> Add new maxlinear,mii-slew-rate-slow boolean property. This property is only applicable for ports in R(G)MII mode and allows for slew rate reduction in comparison to "normal" default configuration with the purpose to reduce radiated emissions.

I would just reuse the pinctrl "slew-rate" property here. The values are binding specific.
