Subject: [PATCH v3 21/25] PCI: v3-semi: Use inbound resources for setup
Date: Mon, 28 Oct 2019 11:32:52 -0500 [thread overview]
Message-ID: <20191028163256.8004-22-robh@kernel.org> (raw)
In-Reply-To: <20191028163256.8004-1-robh@kernel.org>
Now that the helpers provide the inbound resources in the host bridge
'dma_ranges' resource list, convert the v3-semi host bridge to use
the resource list to setup the inbound addresses.
