From ea1332ceb4698b199387b517e640705f93263161 Mon Sep 17 00:00:00 2001 From: Shaohui Xie Date: Fri, 4 Dec 2015 10:22:03 +0800 Subject: [PATCH] net: fm: disables unused FM1-DTSEC1 MAC node in DTS We don't disable unused FM1-DTSEC1 MAC node in FMAN v2 since it is used by MDIO. For FMAN v3, MDIO uses dedicated controller, so we can disable unused FM1-DTSEC1 MAC node to avoid being probed in Linux.
