Subject: support the lubancat stm32mp157 board.
X-Git-Tag: 6.5.0^2~1
X-Git-Url: https://git.ayoreis.com/Adafruit_Blinka-hackapet.git/commitdiff_plain/9a10db06d304126b95f9ca7a706fe202eeb5a1d2

support the lubancat stm32mp157 board.

1\add 'if' block in board.py and analogio.py
2\add board pin description in lubancat_stm32mp157.py
3\add some special pin in stm32mp157/pin.py to support analogio and i2c functions
