The debugfs file pinmux-pins used to tell which function was
enabled but now states simply which device owns the pin. Being
owned by the pinctrl driver itself means just that it's hogged
so be a bit more helpful by printing that.
I somewhat mourn the loss of being able to tell from the debugfs
which function is using a certain pin, does anyone have ideas on
how to go about fixing this properly? The root file
pinctrl-handles does tell it, but requires cross-referencing
which isn't helpful.
