From d482356322c9910541a3118d049718b384a252bd Mon Sep 17 00:00:00 2001 From: Mathias Kresin Date: Tue, 13 Mar 2018 20:06:37 +0100 Subject: [PATCH] ramips: mt7620n: add mdio node and disable port4 by default Revert the changes I applied to aa5014dd1a58 ("ramips: mt7620n: enable port 4 as EPHY by default"). The driver expects a node mdio-bus to be present, regardless of the actual node status. If the node is missing the driver fails to load with mtk_soc_eth 10100000.ethernet: no mdio-bus child node found Disable port4 by default again. If the port is enabled but not present, a "invalid port id 4" warning is shown during boot.
