PocketBeagle is an ultra-tiny-yet-complete open-source USB-key-fob computer.
This board can be indentified by the BPxx value after A335BNLT (BBB)
in the at24 eeprom:
BPxx [aa 55 33 ee 41 33 33 35 42 4e 4c 54 42 50 30 30 |.U3.A335BNLTBP00|]

Changes in v2:
- Use SPDX tags.
- Use eeprom@50, remove repeated node and fix and remove '_' to fix node_name_chars_strict Warning
- Fix: PocketBeagle Name in Subject (not PocketBeagle Blue)
- Fix: leds remove '_' to fix node_name_chars_strict warning
- Fix: node_name_chars_strict pinmux_*_pins label's.

The EEPROM value isn’t right. We made it PBGL instead of using BNLT.

Is there anything preventing the PRU and GPIO pins from being defined? I guess the GPIO pins might not be exposed through SYSFS due to lack of upstream drivers, but could the pinmux at least be set?

Thanks Jason,
Yeah I must have got distracted and coped the one off "PocketBone"
value, in v3 i have it changed to:
+This board family can be indentified by the A335PBGL in the at24 eeprom:
+A2: [aa 55 33 ee 41 33 33 35 50 42 47 4c 30 30 41 32 |.U3.A335PBGL00A2|]
> Is there anything preventing the PRU and GPIO pins from being defined? I guess the GPIO pins might not be exposed through SYSFS due to lack of upstream drivers, but could the pinmux at least be set?
Yeah, we could add those default pinmux's too like I did for spi, (we
use a spidev node, but that can't go mainline)

Hi Robert,
Great to see this. One small comment, the copyright notices for 2012
seem a little unlikely to be 'complete'. I guess a lot is copied from
files dating back that far, but not everything so do we not want to
reflect more recent work on these?
