Subject: [PATCH v5 1/5] dt-bindings: ata: sata: Document the graph port

From: Manivannan Sadhasivam <manivannan.sadhasivam@....qualcomm.com>

An external connector like M.2 could expose the SATA interface to the
plugin cards. So add the graph port to establish link between the SATA Port
and the connector node.
