Hi,
Is there any particular reason to stipulate, (hardware) blink should be turned off, when brightness is set to 0? Following is copied from "Documentation/leds/leds-class.txt"
"Setting the brightness to zero with brightness_set() callback function
should completely turn off the LED and cancel the previously programmed
hardware blinking function, if any."
The chip driver could also use other methods for the same, keeping brightness independent of blink.
For example, delay_on/off
delay_off=0 ==> blink off, led on.
delay_on=0 ==> blink off, led off.
Or am I overlooking something?
Many Thanks,
Tony
