Required sub-node properties:
- cmd-gpio: Command LED GPIO. See OF device-tree GPIO specification.
- slow-gpio: Slow LED GPIO. See OF device-tree GPIO specification.
+- modes-map: A mapping between LED modes (off, on or SATA activity blinking) and
+ the corresponding cmd-gpio/slow-gpio values. All the GPIO values combinations
+ should be given in order to avoid having an unknown mode at driver probe time.
Optional sub-node properties:
