*** BLURB HERE *** Hello there, I recently tested ledtrig-gpio on an embedded controller and one of the issues I had involve not requesting the user input pin as GPIO.
In many embedded systems, a pin could be muxed as several functions, and requesting the pin as GPIO is necessary to let pinmux select the pin as a GPIO instead of, say an I2C pin. I'd like to learn whether it is appropriate to assume user of ledtrig-gpio really intends to use GPIOs and not some weird pins that are used as other functions.
