The BeagleBoard.org PocketBeagle has P1 and P2 headers [0] which expose
many of the TI AM3358 SoC balls to stacking expansion boards called
"capes", or to other external connections like jumper wires connected
to a breadboard.
Note: the AM3358 die is actually embedded inside of the OSD335x-SM
System-in-Package (SiP) [1] but that is irrelevant to the gpio driver.
Many of the P1 and P2 header pins can muxed to a GPIO line. The
gpio-line-names describe which P1 or P2 pin that line goes to and the
default mux for that P1 or P2 pin if it is not GPIO.
Some GPIO lines are named "[NC]" as the corresponding balls are not
routed to anything on the PCB.
The goal for these names is to make it easier for a user viewing the
output of gpioinfo to determine which P1 or P2 pin is connected to a
GPIO line. The output of gpioinfo on a PocketBeagle would be:

Tony - does this look ok for 5.9?
If so, I might start making other variants like BeagleBone Blue and
BeagleBone {Green,Black} Wireless and submit those when ready.
thanks,

Yes looks OK to me.
Just wondering, are the line with "NA" not used internally either?
If the "NA" lines are used internally, we should probably use
"Reserved" or "Internal" or something like that to avoid later
on having to patch them with internal device names..

OK yeah makes sense.

There are many more 'no connects' as the PocketBeagle is much simpler.
There are 12 SYSBOOT pins which just go to fixed pull-up and pull-down
resistors. I'll change those from "[NC]" to "[SYSBOOT]".
Also, after going through all the enteries again, I noticed 4 lines that
I mislabeled.
I will post a v2.
