From 701db6e9c62ce1f61ec83a75b0367b4d46284e27 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Mon, 18 Jun 2018 04:02:15 +0200 Subject: [PATCH] net: ravb: Support reset GPIO both in mac and phy node The recent DTs have the PHY reset GPIO in the PHY node rather than the ethernet MAC node, support extracting the PHY reset GPIO info from both the PHY node and ethernet MAC node.
