This "compatible" name is a bit too generic. No, I don't know a better name :-(
+- label : (optional) the label for this LED. If omitted, the label is + taken from the node name (excluding the unit address).
What is a label? It should be described here. Also, its encoding
should be described ("a string" I guess).
+- gpios : should specify LED GPIO.

+Example:
+
+led@0 {
+ compatible = "gpio-led";
+ label = "hdd";
+ gpios = <&mcu_pio 0 0>;
+};You show a unit address but have no "reg" value. This is incorrect. What would be the parent node of this, btw? Segher
