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.
