10 Mode (gpio-ext bus), delay_on and delay_off.
12 Each LED is represented as a sub-node of the netxbig-leds device.
14 Required sub-node properties:
15 - mode-addr: Mode register address on gpio-ext bus.
16 - mode-val: Mode to value mapping. Each entry is represented by two integers:
17 A mode and the corresponding value on the gpio-ext bus.
