Subject: [PATCH v3 05/26] PCI: keystone: Use platform_get_resource_byname to get memory resources
Date: Mon, 25 Mar 2019 15:09:26 +0530	[thread overview]
Message-ID: <20190325093947.32633-6-kishon@ti.com> (raw)
In-Reply-To: <20190325093947.32633-1-kishon@ti.com>

Use platform_get_resource_byname() instead of platform_get_resource() which
uses index to get memory resources. While at that get the memory resource
defined specifically for configuration space instead of deriving the
configuration space address from dbics address space. Since pci-keystone
driver has never worked out of the box in mainline kernel, dt backward
compatibility is ignored.
