Subject: [PATCHv8 12/12] misc: pci_endpoint_test: Add driver data for Layerscape PCIe controllers
Date: Fri, 18 Sep 2020 16:00:24 +0800	[thread overview]
Message-ID: <20200918080024.13639-13-Zhiqiang.Hou@nxp.com> (raw)
In-Reply-To: <20200918080024.13639-1-Zhiqiang.Hou@nxp.com>

From: Hou Zhiqiang <Zhiqiang.Hou@nxp.com>

The commit 0a121f9bc3f5 ("misc: pci_endpoint_test: Use streaming DMA
APIs for buffer allocation") changed to use streaming DMA APIs, however,
dma_map_single() might not return a 4KB aligned address, so add the
default_data as driver data for Layerscape PCIe controllers to make it
4KB aligned.
