From 49714461b7970acb38c421a48f5d7f782e360003 Mon Sep 17 00:00:00 2001 From: Alexandru Tachici Date: Fri, 29 Apr 2022 18:34:37 +0300 Subject: dt-bindings: net: phy: Add 10-baseT1L 2.4 Vpp Add a tristate property to advertise desired transmit level. If the device supports the 2.4 Vpp operating mode for 10BASE-T1L, as defined in 802.3gc, and the 2.4 Vpp transmit voltage operation is desired, property should be set to 1. This property is used to select whether Auto-Negotiation advertises a request to operate the 10BASE-T1L PHY in increased transmit level mode. If property is set to 1, the PHY shall advertise a request to operate the 10BASE-T1L PHY in increased transmit level mode. If property is set to zero, the PHY shall not advertise a request to operate the 10BASE-T1L PHY in increased transmit level mode.
