From a32def781f5a840697e503f1da29de455a875bbc Mon Sep 17 00:00:00 2001 From: Aleksander Jan Bajkowski Date: Sun, 12 Mar 2023 10:59:21 +0100 Subject: [PATCH] lantiq: xway: add phy reset pin to AVM Fritz!Box 7320 This commit adds the PHY reset gpio for the LAN1 port to the dts. According to the GPL sources, gpios 34 and 36 are used on the AVM FritzBox 7320 and 7330. The second port is unsupported. The gpio assignment has been verified on the FritzBox 7330.
