base-files: gpio switch: set output value with direction
Use the "low" and "high" values to configure the GPIO as an output with that initial value. It ensures that the gpio doesn't have a unwanted value during the time the direction is set to ouput and the actual value is applied. We don't need to take care of the GPIO polarity for now, since our exported GPIOs are always active low. Signed-off-by: Mathias Kresin <dev@kresin.me>owl
