Subject: [PATCH net-next v5 1/4] dt-bindings: net: Add tx and rx internal delays
Date: Tue, 2 Jun 2020 11:45:19 -0500 [thread overview]
Message-ID: <20200602164522.3276-2-dmurphy@ti.com> (raw)
In-Reply-To: <20200602164522.3276-1-dmurphy@ti.com>
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.
