From 42175a35534aab13016297fb48763e9f1126a0ab Mon Sep 17 00:00:00 2001 From: Phil Edworthy Date: Fri, 2 Oct 2015 11:25:06 +0100 Subject: [PATCH] PCI: rcar: Set root bus nr to that provided in DT On ARM64, setting the root bus number to -1 causes probe failure. Moreover, we should use the bus number specified in the DT as we could have multiple PCIe controllers with different bus ranges.
