   4 Subject: [PATCH 1/3] ARM: dts: Enable SRAB switch and GMACs on 5301x DTS
   5
   6 Add the Switch Register Access Block which is a special piece of
   7 hardware allowing us to perform indirect read/writes towards the
   8 integrated BCM5301X Ethernet switch.
   9
  10 We also add the 4 Gigabit MAC Device Tree nodes within the brcm,bus-axi
  11 bus node to get proper binding between the BCMA instantiated core and
  12 the Device Tree nodes. We will need that to be able to reference
  13 Ethernet Device Tree nodes in a future patch adding the switch ports
  14 layout.
