From e1d7b0b9c55a105ec8b9d8bcb24d68fc7b74789a Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sat, 13 Nov 2021 03:26:05 +0100 Subject: [PATCH] ARM: stm32: Increase PHY auto-negotiation timeout to 20s on DHSOM The Micrel PHYs on known DHSOM based boards take a while to come out of reset, increase the auto-negotiation timeout to prevent it from timing out in case the ethernet is used right after the board was reset.
