Subject: ARM: dts: renesas: Add compatible properties to LAN8710A Ethernet PHYs
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=c1466c55de7819760ae7387e3ca18a6d6fb8dbb7;p=u-boot.git

ARM: 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.

Ported from Linux kernel commit 1c65ef1c71e473c00f2a7a1b9c140f0b4862f282 .
