+Subject: [PATCH 1/4] bcm63xx_enet: just use "enet" as the clock name
+
+Now that we have the individual clocks available as "enet" we
+don't need to rely on the device id for them anymore.

+Subject: [PATCH 3/4] bcm63xx_enet: remove pointless mac_id check
+
+Enabling the ephy clock for mac 1 is harmless, and the actual usage of
+the ephy is not restricted to mac 0, so we might as well remove the
+check.
