Subject: [PATCH 4/9] iARM: dts: renesas: Add compatible properties to LAN8710A Ethernet PHYs

Add compatible values to Ethernet PHY subnodes representing SMSC
LAN8710A PHYs on RZ/A1 and R-Mobile A1 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@...der.be>
---
I could not verify the PHY revision number (least significant nibble of
the ID) on gr-peach, due to lack of hardware.
