Hi, I am trying to send the brightness value ( for 5 channels) by echo "val1val2val3val4val5" > brightness ,
How did you infer this format? Please get acquainted with Documentation/leds/leds-class.txt and Documentation/ABI/testing/sysfs-class-led.
But seems like even if I change the brightness type to enum or int in my driver ,I will never be able to send the brightness string because led class defines the brightness value as enum.
One LED class device can control one channel.
extern void led_set_brightness(struct led_classdev *led_cdev, enum led_brightness brightness); Only possible way I am finding is to create attributes for each channel like brightness,default trigger,max_brightness and any user defined attributes, but i am not getting how to do this. Can some on please comment or post the link to the example driver. Do i have to call led_class_register for every channel and I have to define every channel in the device tree?
Just grep through drivers/leds and Documentation/devicetree/bindings/leds/. -- Best regards, Jacek Anaszewski -- To unsubscribe from this list: send the line "unsubscribe linux-leds" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
