From 312011e8e7ba1a5cf2234dae73daa8304f5993dd 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.
