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>;
blue-power {
label = "netxbig:blue:power";
mode-addr = <0>;
mode-val = <NETXBIG_LED_OFF 0
NETXBIG_LED_ON 1
NETXBIG_LED_TIMER1 3
NETXBIG_LED_TIMER2 7>;
bright-addr = <1>;
max-brightness = <7>;
};
red-power {
label = "netxbig:red:power";
mode-addr = <0>;
mode-val = <NETXBIG_LED_OFF 0
NETXBIG_LED_ON 2
NETXBIG_LED_TIMER1 4>;
bright-addr = <1>;
max-brightness = <7>;
};
blue-sata0 {
label = "netxbig:blue:sata0";
mode-addr = <3>;
mode-val = <NETXBIG_LED_OFF 0
NETXBIG_LED_ON 7
NETXBIG_LED_SATA 1
NETXBIG_LED_TIMER1 3>;
bright-addr = <2>;
max-brightness = <7>;
};
red-sata0 {
label = "netxbig:red:sata0";
mode-addr = <3>;
mode-val = <NETXBIG_LED_OFF 0
NETXBIG_LED_ON 2
NETXBIG_LED_TIMER1 4>;
bright-addr = <2>;
max-brightness = <7>;
};
blue-sata1 {
label = "netxbig:blue:sata1";
mode-addr = <4>;
mode-val = <NETXBIG_LED_OFF 0
NETXBIG_LED_ON 7
NETXBIG_LED_SATA 1
NETXBIG_LED_TIMER1 3>;
bright-addr = <2>;
max-brightness = <7>;
};
red-sata1 {
label = "netxbig:red:sata1";
mode-addr = <4>;
mode-val = <NETXBIG_LED_OFF 0
NETXBIG_LED_ON 2
NETXBIG_LED_TIMER1 4>;

max-brightness = <7>;
};
};
