There should be a dash in LED node name, please pass this dts via
dt_binding_check
  led-0 {
    ...
  };

Also why not add the `color` property to the LED? This is DTS for a
specific device, right?
`label` is obsolete. The LED subsystem creates a name in form
  [device:]color:function
If this LED should blink for activity on port 2 (is this an ethernet
port?), the function should be LED_FUNCTION_LAN and function-enumerator
should be <2> (or function should be LED_FUNCTION_ACTIVITY, depending
on how the LED subsystem goes forward with this, but certainly not
LED_FUNCTION_STATUS), and trigger-sources should be set to point to the
ethernet port.

Luka, are you willing to change this once we solve this API properly
in LED subsystem?

led-6. LED_FUNCTION_DISK. `label` deprecated.

Again, `label` is deprecated. Rather use function =
<LED_FUNCTION_POWER>;
