On the board n090401 (Seagate NAS 4-Bay), the LED mode mapping (GPIO values to LED mode) is different from the one used on other boards supported by the leds-ns2 driver. With this patch the hardcoded mapping is removed from leds-ns2. Now, it must be defined either in the platform data (if an old-fashion board setup file is used) or in the DT node. In order to allow the later, this patch also introduces a modes-map property for the leds-ns2 DT binding.

Binding for dual-GPIO LED found on Network Space v2 (and parents).
|
|
|
|
Required properties:
|
|
- compatible: "lacie,ns2-leds".
|
|
|
|
Each LED is represented as a sub-node of the ns2-leds device.
|
|
|
|
Required sub-node properties:
|
|
- cmd-gpio: Command LED GPIO. See OF device-tree GPIO specification.
|
|
- slow-gpio: Slow LED GPIO. See OF device-tree GPIO specification.
|
|
- modes-map: A mapping between LED modes (off, on or SATA activity blinking) and
|
|
the corresponding cmd-gpio/slow-gpio values. All the GPIO values combinations
|
|
should be given in order to avoid having an unknown mode at driver probe time.
|
|
|
|
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:
|
|
|
|
#include <dt-bindings/leds/leds-ns2.h>
|
|
|
|
ns2-leds {
|
|
compatible = "lacie,ns2-leds";
|
|
|
|
blue-sata {
|
|
label = "ns2:blue:sata";
|
|
slow-gpio = <&gpio0 29 0>;
|
|
cmd-gpio = <&gpio0 30 0>;
|
|
modes-map = <NS_V2_LED_OFF 0 1
|
|
NS_V2_LED_ON 1 0
|
|
NS_V2_LED_ON 0 0
|
|
NS_V2_LED_SATA 1 1>;
|
|
};
|
