From: Dan Murphy Date: Wed, 24 Jun 2020 12:16:01 +0000 (-0500) Subject: dt-bindings: net: Add tx and rx internal delays X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9150069bf5fc0e86;p=linux.git 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. Signed-off-by: Dan Murphy Signed-off-by: David S.
