From baaac2fb0dda4ce2204e6650138cd578c4b11236 Mon Sep 17 00:00:00 2001 From: Moritz Fischer Date: Mon, 4 Feb 2019 09:30:40 -0800 Subject: dt-bindings: net: Add fixed-link support Update device-tree binding with fixed-link support. With fixed-link support the formerly required property 'phy-handle' is now optional if 'fixed-link' child is present. Signed-off-by: Moritz Fischer Signed-off-by: David S.
