Binding for the CPLD LEDs (GPIO extension bus) found on some LaCie/Seagate
|
|
boards (Example: 2Big/5Big Network v2, 2Big NAS).
|
|
|
|
Required properties:
|
|
- compatible: "lacie,netxbig-leds".
|
|
- gpio-ext: Phandle for the gpio-ext bus.
|
|
|
|
Optional properties:
|
|
- timers: Timer array. Each timer entry is represented by three integers:
|
|
Mode (gpio-ext bus), delay_on and delay_off.
|
|
|
|
Each LED is represented as a sub-node of the netxbig-leds device.
|
|
|
|
Required sub-node properties:
|
|
- mode-addr: Mode register address on gpio-ext bus.
|
|
- mode-val: Mode to value mapping. Each entry is represented by two integers:
|
|
A mode and the corresponding value on the gpio-ext bus.
|
|
- bright-addr: Brightness register address on gpio-ext bus.
|
|
- max-brightness: Maximum brightness value.
|
|
|
|
Optional sub-node properties:
|
|
- label: Name for this LED. If omitted, the label is taken from the node name.
|
|
- linux,default-trigger: Trigger assigned to the LED.
|
|
|
|
