Guenter, I have a question regarding this. I see that gpio-fan reads
the state of gpios and uses this as the initial setting.
Led-pwm on init sets the brightness to LED_OFF.
What should be the default state after init? Should the fan be off or
at full power? I am thinking about adding an optional node to device
tree that could be used to set this. But the question remains - what
should be the default setting?
Trick question ... I can not really answer it. you can try the devicetree
option, but be prepared to have it rejected - the usual argument is that
dt shall only describe the HW but not its configuration.
Ultimately, either way is fine with me.
