From 8b3c313515c1ae37be9d61a4e92c4bf4b43f605f Mon Sep 17 00:00:00 2001 From: David Bauer Date: Sun, 24 Apr 2022 23:48:42 +0200 Subject: [PATCH] mpc85xx: define reset-delay for WS-AP3825i eth PHY The WS-AP3825i uses Atheros PHYs which according to the datasheet require the reset to be asserted for at least 1 ms. This fixes broken eth1 upon soft-reboot. eth0 is no affected, as the ifup / ifdown cycle in preinit prevents this issue from happening when the system is ready.
