From 260887c770eb60f57176bccf011fd0fe1bc62dc5 Mon Sep 17 00:00:00 2001 From: Álvaro Fernández Rojas Date: Tue, 21 Mar 2023 18:33:58 +0100 Subject: net: dsa: b53: mmap: allow passing a chip ID MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit BCM6318 and BCM63268 SoCs require a special handling for their RGMIIs, so we should be able to identify them as a special BCM63xx switch.
