From d3e014ec7d5ebe9644b5486bc530b91e62bbf624 Mon Sep 17 00:00:00 2001 From: Padmanabhan Rajanbabu Date: Thu, 19 Dec 2019 15:47:01 +0530 Subject: net: stmmac: platform: Fix MDIO init for platforms without PHY The current implementation of "stmmac_dt_phy" function initializes the MDIO platform bus data, even in the absence of PHY. This fix will skip MDIO initialization if there is no PHY present.
