Why void and not the specific type?

Ok, I will fix it for using u32 __iomem *.

Hmm, having something called "fecp" that is a different type than other 
"fecp"s could be confusing.

Ok, I will use 'regp' instead of 'fecp' then.

You can put a data pointer in the of_platform match struct, instead of 
re-checking the compatible.

.data pointer in 'fs_enet_mdio_fec_match' is already used for
mpc5xxx_get_bus_frequency(). Setting .data to some sort of FEC ID in
match struct for "fsl,pq1-fec-mdio" would be confusing to.
Would a simple

if (!strncmp(match->compatible, "fsl,mpc5121-fec-mdio",
             sizeof(match->compatible))) {

suffice here?

Thanks!
