The function that a pin is muxed to can be read from the top-level pinctrl-maps debugfs file. However, this only reflects the values that were specified in device tree, so they will only show deviations from the hardware default setting. Display the current pinmux setting in the per-controller pinconf-groups debugfs file along with the rest of the per-pin configuration settings.
