+Subject: [PATCH] net: stmmac: Deprecate snps, phy-addr and auto-detect PHY
+ address
+
+The snps,phy-addr device tree property is non-standard, and should be
+removed in favor of proper phy node support. Remove it from the binding
+documents and warn if the property is still used.
+
+Most PHYs respond to address 0, but a few don't, so auto-detect PHY
+address by default, to make up for the lack of explicit address selection.
