+Subject: net: stmmac: dwmac-sun8i: fix allwinner,leds-active-low handling
+
+The driver expect "allwinner,leds-active-low" to be in PHY node, but
+the binding doc expect it to be in MAC node.
+
+Since all board DT use it also in MAC node, the driver need to search
+allwinner,leds-active-low in MAC node.
