From 3888c8d1979289efe685fe29276aed4d4b685975 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Thu, 20 Sep 2018 09:42:27 +0200 Subject: [PATCH] net: zynq_gem: Add support for fixed-link phy Based on dt-specs fixed-link doesn't require phy-handle to be used. Fix driver to only read phy related setting when phy-handle is found.
