Kernel-4.18.0-80.el8_leds-netxbig

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.

Example:

netxbig-leds {
compatible = “lacie,netxbig-leds”;

gpio-ext = &gpio_ext;

timers = <NETXBIG_LED_TIMER1 500 500
      NETXBIG_LED_TIMER2 500 1000>;
