Subject: [PATCH net-next v4 2/4] dt-bindings: net: Add Rx/Tx output configuration for 10base T1L
Date: Tue, 17 Nov 2020 14:15:53 -0600 [thread overview]
Message-ID: <20201117201555.26723-3-dmurphy@ti.com> (raw)
In-Reply-To: <20201117201555.26723-1-dmurphy@ti.com>
Per the 802.3cg spec the 10base T1L can operate at 2 different
differential voltages 1v p2p and 2.4v p2p. The abiility of the PHY to
drive that output is dependent on the PHY's on board power supply.
This common feature is applicable to all 10base T1L PHYs so this binding
property belongs in a top level ethernet document.
