Subject: [PATCHv2 3/7] dt-bindings: pci: layerscape-pci: Add a optional property big-endian
Date: Tue, 27 Oct 2020 15:29:57 +0800	[thread overview]
Message-ID: <20201027073001.41808-4-Zhiqiang.Hou@nxp.com> (raw)
In-Reply-To: <20201027073001.41808-1-Zhiqiang.Hou@nxp.com>

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

This property is to indicate the endianness when accessing the
PEX_LUT and PF register block, so if these registers are
implemented in big-endian, specify this property.
