pinctrl: st: Display pin's function when printing pinctrl debug information
Great for easily determining which mode a pin is operating in.
This patch was particularly helpful when debugging a recent GPIO/
Pinctrl disparity issue.
Before:
$ cat /sys/kernel/debug/pinctrl/<pin-controller>/pinconf-pins
pin 33 (PIO4[1]):[OE:0,PU:0,OD:0]
[retime:0,invclk:0,clknotdat:0,de:0,rt-clk:0,rt-delay:0]
After [GPIO]:
$ cat /sys/kernel/debug/pinctrl/<pin-controller>/pinconf-pins
pin 33 (PIO4[1]):[OE:0,PU:0,OD:0] GPIO
[retime:0,invclk:0,clknotdat:0,de:0,rt-clk:0,rt-delay:0]
After [Alt]:
$ cat /sys/kernel/debug/pinctrl/<pin-controller>/pinconf-pins
pin 33 (PIO4[1]):[OE:0,PU:0,OD:0] Alt Fn 2
[retime:0,invclk:0,clknotdat:0,de:0,rt-clk:0,rt-delay:0]
