Date: Mon, 27 Mar 2017 10:49:46 +0100 From: Lorenzo Pieralisi <lorenzo.pieralisi@....com> To: linux-pci@...r.kernel.org Cc: linux-kernel@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, Lorenzo Pieralisi <lorenzo.pieralisi@....com>, Bjorn Helgaas <bhelgaas@...gle.com>, Tanmay Inamdar <tinamdar@....com> Subject: [PATCH v2 18/22] PCI: xgene: update PCI config space remap function PCI configuration space should be mapped with a memory region type that generates on the CPU host bus non-posted write transations. Update the driver to use the devm_ioremap_nopost* interface to make sure the correct memory mappings for PCI configuration space are used.
