From 73375530df21066a97a70c4f626b9b7367371ec0 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sat, 13 Nov 2021 03:27:37 +0100 Subject: [PATCH] ARM: dts: stm32: Add custom PHY reset bindings on AV96 The ethernet PHY must be reset on AV96, however DWMAC currently does not support the MDIO-bus PHY GPIO reset bindings and the ethernet MAC PHY reset property is going away on next DT sync. Add PHY specific reset bindings to trigger the PHY reset and fix sporadic ethernet malfunctions, until the next DT sync.
