| Tom Rini | 53633a8 | 2024-02-29 12:33:36 -0500 | [diff] [blame] | 1 | Binding for the CPLD LEDs (GPIO extension bus) found on some LaCie/Seagate |
| 2 | boards (Example: 2Big/5Big Network v2, 2Big NAS). |
| 3 | |
| 4 | Required properties: |
| 5 | - compatible: "lacie,netxbig-leds". |
| 6 | - gpio-ext: Phandle for the gpio-ext bus. |
| 7 | |
| 8 | Optional properties: |
| 9 | - timers: Timer array. Each timer entry is represented by three integers: |
| 10 | Mode (gpio-ext bus), delay_on and delay_off. |
| 11 | |
| 12 | Each LED is represented as a sub-node of the netxbig-leds device. |
| 13 | |
| 14 | Required 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 | |
| 21 | Optional 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. |
