Subject: Add Coral Dev Board Mini support (MT8167).
X-Git-Tag: 5.9.0^2~1
X-Git-Url: https://git.ayoreis.com/Adafruit_Blinka-hackapet.git/commitdiff_plain/3588271b3afe701348ac1b32e69b92fec0131c77?ds=sidebyside

Add Coral Dev Board Mini support (MT8167).

Also rename the other Coral board pin module for consistency.
