Subject: [PATCH v4 09/21] PCI: xilinx-nwl: update PCI config space remap function
Date: Wed, 19 Apr 2017 17:48:58 +0100	[thread overview]
Message-ID: <20170419164913.19674-10-lorenzo.pieralisi@arm.com> (raw)
In-Reply-To: <20170419164913.19674-1-lorenzo.pieralisi@arm.com>

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.
