From fa436cedc262c7c95817e64877f8db0c9d386ab8 Mon Sep 17 00:00:00 2001 From: Robert Hancock Date: Thu, 6 Jun 2019 16:28:20 -0600 Subject: [PATCH] net: axienet: document device tree mdio child node The mdio child node for the MDIO bus is generally required when using this driver but was not documented other than being shown in the example. Document it as an optional (but usually required) parameter. Signed-off-by: Robert Hancock Signed-off-by: David S.
