Subject: [PATCH v14 12/17] OF/PCI: Add IORESOURCE_MEM_64 for 64-bit resource
Date: Fri, 16 Sep 2016 13:02:02 -0700 [thread overview]
Message-ID: <20160916200207.21439-13-yinghai@kernel.org> (raw)
In-Reply-To: <20160916200207.21439-1-yinghai@kernel.org>
For device resource PREF bit setting under bridge 64-bit pref resource,
we need to make sure only set PREF for 64bit resource.
This patch set IORESOUCE_MEM_64 for 64bit resource during OF device
resource flags parsing.
