circuitpython/stmhal/pin.h
Damien George 7a37f647a5 Merge branch 'teensy-new' of github.com:dhylands/micropython into dhylands-teensy-new
Conflicts:
	stmhal/pin_named_pins.c
	stmhal/readline.c

Renamed HAL_H to MICROPY_HAL_H.  Made stmhal/mphal.h which intends to
define the generic Micro Python HAL, which in stmhal sits above the ST
HAL.
