1Binding for the CPLD LEDs (GPIO extension bus) found on some LaCie/Seagate2boards (Example: 2Big/5Big Network v2, 2Big NAS).3 4Required properties:5- compatible: "lacie,netxbig-leds".6- gpio-ext: Phandle for the gpio-ext bus.7 8Optional properties:9- timers: Timer array. Each timer entry is represented by three integers:10 Mode (gpio-ext bus), delay_on and delay_off.11 12Each LED is represented as a sub-node of the netxbig-leds device.13 14Required 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.18- bright-addr: Brightness register address on gpio-ext bus.19- max-brightness: Maximum brightness value.20 21Optional sub-node properties:22- label: Name for this LED. If omitted, the label is taken from the node name.23- linux,default-trigger: Trigger assigned to the LED.24 25Example:26 27netxbig-leds {28 compatible = "lacie,netxbig-leds";29 30 gpio-ext = &gpio_ext;31 32 timers = <NETXBIG_LED_TIMER1 500 50033 NETXBIG_LED_TIMER2 500 1000>;34 35 blue-power {36 label = "netxbig:blue:power";37 mode-addr = <0>;38 mode-val = <NETXBIG_LED_OFF 039 NETXBIG_LED_ON 140 NETXBIG_LED_TIMER1 341 NETXBIG_LED_TIMER2 7>;42 bright-addr = <1>;43 max-brightness = <7>;44 };45 red-power {46 label = "netxbig:red:power";47 mode-addr = <0>;48 mode-val = <NETXBIG_LED_OFF 049 NETXBIG_LED_ON 250 NETXBIG_LED_TIMER1 4>;51 bright-addr = <1>;52 max-brightness = <7>;53 };54 blue-sata0 {55 label = "netxbig:blue:sata0";56 mode-addr = <3>;57 mode-val = <NETXBIG_LED_OFF 058 NETXBIG_LED_ON 759 NETXBIG_LED_SATA 160 NETXBIG_LED_TIMER1 3>;61 bright-addr = <2>;62 max-brightness = <7>;63 };64 red-sata0 {65 label = "netxbig:red:sata0";66 mode-addr = <3>;67 mode-val = <NETXBIG_LED_OFF 068 NETXBIG_LED_ON 269 NETXBIG_LED_TIMER1 4>;70 bright-addr = <2>;71 max-brightness = <7>;72 };73 blue-sata1 {74 label = "netxbig:blue:sata1";75 mode-addr = <4>;76 mode-val = <NETXBIG_LED_OFF 077 NETXBIG_LED_ON 778 NETXBIG_LED_SATA 179 NETXBIG_LED_TIMER1 3>;80 bright-addr = <2>;81 max-brightness = <7>;82 };83 red-sata1 {84 label = "netxbig:red:sata1";85 mode-addr = <4>;86 mode-val = <NETXBIG_LED_OFF 087 NETXBIG_LED_ON 288 NETXBIG_LED_TIMER1 4>;89 bright-addr = <2>;90 max-brightness = <7>;91 };92};93
