[PATCH 8/9] arm64: dts: renesas: Add compatible properties to KSZ9031 Ethernet PHYs

Geert Uytterhoeven geert+renesas at glider.be
Thu Sep 9 01:49:44 PDT 2021


Add compatible values to Ethernet PHY subnodes representing Micrel
KSZ9031 PHYs on R-Car Gen3 boards.  This allows software to identify the
PHY model at any time, regardless of the state of the PHY reset line.

Signed-off-by: Geert Uytterhoeven <geert+renesas at glider.be>

I could not verify the PHY revision number (least significant nibble of
the ID) on eagle, v3msk, conder, and v3hsk, due to lack of hardware.
