From 250a93501d6265bbb9ddf06af25ac9ae64782297 Mon Sep 17 00:00:00 2001 From: Darren Stevens Date: Wed, 25 Jul 2018 21:55:18 +0100 Subject: [PATCH] powerpc/pasemi: Search for PCI root bus by compatible property Pasemi arch code finds the root of the PCI-e bus by searching the device-tree for a node called 'pxp'. But the root bus has a compatible property of 'pasemi,rootbus' so search for that instead.
