1Binding for the CPLD LEDs (GPIO extension bus) found on some LaCie/Seagate 2boards (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 500 500 33 NETXBIG_LED_TIMER2 500 1000>; 34 35 blue-power { 36 label = "netxbig:blue:power"; 37 mode-addr = <0>; 38 mode-val = <NETXBIG_LED_OFF 0 39 NETXBIG_LED_ON 1 40 NETXBIG_LED_TIMER1 3 41 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 0 49 NETXBIG_LED_ON 2 50 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 0 58 NETXBIG_LED_ON 7 59 NETXBIG_LED_SATA 1 60 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 0 68 NETXBIG_LED_ON 2 69 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 0 77 NETXBIG_LED_ON 7 78 NETXBIG_LED_SATA 1 79 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 0 87 NETXBIG_LED_ON 2 88 NETXBIG_LED_TIMER1 4>; 89 bright-addr = <2>; 90 max-brightness = <7>; 91 }; 92}; 93
