Shouldn't this be under net/pcs?

Rest looks good to me:

There's no net/pcs, since this is the first of its kind. There's no net/phy
either, so I didn't bother creating one.

+description: |
+  Lynx SerDes devices may contain several Ethernet protocol controllers. These
+  controllers convert between (X)GMII and a variety of high-speed interfaces
+  (SGMII, 10GBase-R, QSGMII, etc). Unlike the SerDes itself, the PCSs are
+  accessed over an internal MDIO bus.
