From f8efc159ecface4faa5793f861399ae2a60d66bd Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Thu, 24 Apr 2014 18:00:22 +1000 Subject: [PATCH] powerpc/powernv: Reset root port in firmware commit 372cf1244d7c271806b83b32b09a1c8b1b31b353 upstream. Resetting root port has more stuff to do than that for PCIe switch ports and we should have resetting root port done in firmware instead of the kernel itself. The problem was introduced by commit 5b2e198e ("powerpc/powernv: Rework EEH reset").
