From 133387e6303c092195a927fa3cf6af48a645a6fd Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Mon, 24 Jul 2017 16:59:01 +1000 Subject: [PATCH] ftgmac100: Increase reset timeout We had reports of 50us not being sufficient to reset the MAC, thus hitting the "Hardware reset failed" error bringing the interface up on some AST2400 based machines. This bumps the timeout to 200us. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: David S.
