+From 797cf96a09d1d4ee851a3998e590f7641cfc9b9a Mon Sep 17 00:00:00 2001
+From: Jonathan Bell <jonathan@raspberrypi.org>

+Subject: [PATCH] phy: broadcom: split out the BCM54213PE from the
+ BCM54210E IDs
+
+The last nibble is a revision ID, and the 54213pe is a later rev
+than the 54210e. Running the 54210e setup code on a 54213pe results
+in a broken RGMII interface.
