Hello all, I was wondering if it's possible to configure a GPIO pin on the Beaglebone black as a bidirectional GPIO via device tree overlays. Essentially allowing the developer to control the pins direction via the /sys/class/gpio/gpioxx/direction file in sysfs.
A close look at the pinmux table/registers in the TRM reveals that setting bit 5 enables the receiver (input) and clearing bit 5 disables the receiver (input). If I enable the receiver can I use the GPIO pin as both input and output or would it have to be input only ? And if that isn't possible is there any other way to use the GPIO pins bidirectionally without having to dynamically load device tree overlays every time we need to change the direction of a GPIO ?
