From 877b7cb0b6f283593a663134ee52703f12c895cc Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Sat, 19 May 2018 22:31:34 +0200 Subject: net: dsa: mv88e6xxx: Add minimal platform_data support Not all the world uses device tree. Some parts of the world still use platform devices and platform data. Add basic support for probing a Marvell switch via platform data.
