Tom Rini | 53633a8 | 2024-02-29 12:33:36 -0500 | [diff] [blame^] | 1 | Binding for dual-GPIO LED found on Network Space v2 (and parents). |
| 2 | |
| 3 | Required properties: |
| 4 | - compatible: "lacie,ns2-leds". |
| 5 | |
| 6 | Each LED is represented as a sub-node of the ns2-leds device. |
| 7 | |
| 8 | Required sub-node properties: |
| 9 | - cmd-gpio: Command LED GPIO. See OF device-tree GPIO specification. |
| 10 | - slow-gpio: Slow LED GPIO. See OF device-tree GPIO specification. |
| 11 | - modes-map: A mapping between LED modes (off, on or SATA activity blinking) and |
| 12 | the corresponding cmd-gpio/slow-gpio values. All the GPIO values combinations |
| 13 | should be given in order to avoid having an unknown mode at driver probe time. |
| 14 | |
| 15 | Optional sub-node properties: |
| 16 | - label: Name for this LED. If omitted, the label is taken from the node name. |
| 17 | - linux,default-trigger: Trigger assigned to the LED. |
| 18 | |
| 19 | Example: |
| 20 | |
| 21 | #include <dt-bindings/leds/leds-ns2.h> |
| 22 | |
| 23 | ns2-leds { |
| 24 | compatible = "lacie,ns2-leds"; |
| 25 | |
| 26 | blue-sata { |
| 27 | label = "ns2:blue:sata"; |
| 28 | slow-gpio = <&gpio0 29 0>; |
| 29 | cmd-gpio = <&gpio0 30 0>; |
| 30 | modes-map = <NS_V2_LED_OFF 0 1 |
| 31 | NS_V2_LED_ON 1 0 |
| 32 | NS_V2_LED_ON 0 0 |
| 33 | NS_V2_LED_SATA 1 1>; |
| 34 | }; |
| 35 | }; |
