1 From 417b5a156ca8ab4c986c9deacf58309ce4e09410 Mon Sep 17 00:00:00 2001
2 From: Vladimir Oltean <vladimir.oltean@nxp.com>
3 Date: Thu, 14 Nov 2019 17:03:27 +0200
4 Subject: [PATCH] net: mscc: ocelot: publish structure definitions to
5 include/soc/mscc/ocelot.h
6
7 We will be registering another switch driver based on ocelot, which
8 lives under drivers/net/dsa.
9
10 Make sure the Felix DSA front-end has the necessary abstractions to
11 implement a new Ocelot driver instantiation. This includes the function
12 prototypes for implementing DSA callbacks.
