From 0b14c86e3333b934a5c55bbbc564fcf8ddfc0e18 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.
