1*4882a593SmuzhiyunBinding for dual-GPIO LED found on Network Space v2 (and parents).
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun- compatible: "lacie,ns2-leds".
5*4882a593Smuzhiyun
6*4882a593SmuzhiyunEach LED is represented as a sub-node of the ns2-leds device.
7*4882a593Smuzhiyun
8*4882a593SmuzhiyunRequired sub-node properties:
9*4882a593Smuzhiyun- cmd-gpio: Command LED GPIO. See OF device-tree GPIO specification.
10*4882a593Smuzhiyun- slow-gpio: Slow LED GPIO. See OF device-tree GPIO specification.
11*4882a593Smuzhiyun- modes-map: A mapping between LED modes (off, on or SATA activity blinking) and
12*4882a593Smuzhiyun  the corresponding cmd-gpio/slow-gpio values. All the GPIO values combinations
13*4882a593Smuzhiyun  should be given in order to avoid having an unknown mode at driver probe time.
14*4882a593Smuzhiyun
15*4882a593SmuzhiyunOptional sub-node properties:
16*4882a593Smuzhiyun- label: Name for this LED. If omitted, the label is taken from the node name.
17*4882a593Smuzhiyun- linux,default-trigger: Trigger assigned to the LED.
