[PATCH v2 2/2] net: dsa: b53: mdio: add support for BCM53134
From: Álvaro Fernández Rojas
Date: Fri Mar 24 2023 - 04:42:04 EST
From: Paul Geurts <paul.geurts@xxxxxxxxxxxxxxxxxxxxxxxxx>
Add support for the BCM53134 Ethernet switch in the existing b53 dsa driver.
BCM53134 is very similar to the BCM58XX series.
