[PATCH 9/9] arm64: dts: renesas: Add compatible properties to RTL8211E Ethernet PHYs

Thu Sep 9 01:49:45 PDT 2021


Add compatible values to Ethernet PHY subnodes representing Realtek
RTL8211E PHYs on RZ/G2 boards.  This allows software to identify the PHY
model at any time, regardless of the state of the PHY reset line.
