Can we make the dts configured GPIO line name show up in the pinctrl output directly? This would allow grepping for the device specific GPIO line name directly in from the debugfs "pins" output. But Ideally this should be done with the gpio sysfs interface though somehow rather than rely on pinctrl debugfs. The debugfs interface should be optional, and can change. Regards, Tony
