+Subject: [PATCH 1/3] ARM: dts: Enable SRAB switch and GMACs on 5301x DTS
+
+Add the Switch Register Access Block which is a special piece of
+hardware allowing us to perform indirect read/writes towards the
+integrated BCM5301X Ethernet switch.
+
+We also add the 4 Gigabit MAC Device Tree nodes within the brcm,bus-axi
+bus node to get proper binding between the BCMA instantiated core and
+the Device Tree nodes. We will need that to be able to reference
+Ethernet Device Tree nodes in a future patch adding the switch ports
+layout.
