Date: Mon, 27 Feb 2017 15:14:25 +0000 From: Lorenzo Pieralisi <lorenzo.pieralisi@....com> To: linux-pci@...r.kernel.org, linux-arm-kernel@...ts.infradead.org Cc: linux-kernel@...r.kernel.org, linux-arch@...r.kernel.org, Lorenzo Pieralisi <lorenzo.pieralisi@....com>, Bjorn Helgaas <bhelgaas@...gle.com>, Gabriele Paoloni <gabriele.paoloni@...wei.com>, Zhou Wang <wangzhou1@...ilicon.com> Subject: [PATCH 14/20] PCI: hisi: 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_pci_remap_cfg* interface to make sure the correct memory mappings for PCI configuration space are used.
