Date: Wed, 24 Jun 2020 07:16:01 -0500 From: Dan Murphy <dmurphy@...com> To: <andrew@...n.ch>, <f.fainelli@...il.com>, <hkallweit1@...il.com>, <davem@...emloft.net>, <robh@...nel.org> CC: <netdev@...r.kernel.org>, <linux-kernel@...r.kernel.org>, <devicetree@...r.kernel.org>, Dan Murphy <dmurphy@...com> Subject: [PATCH net-next v11 1/5] dt-bindings: net: Add tx and rx internal delays tx-internal-delays and rx-internal-delays are a common setting for RGMII capable devices. These properties are used when the phy-mode or phy-controller is set to rgmii-id, rgmii-rxid or rgmii-txid. These modes indicate to the controller that the PHY will add the internal delay for the connection.
