robert-hh 2f365d234e mimxrt/machine_rtc: Add the RTC class to the machine module. 
Initial version, using the LP RTC clock.  It provides setting the date and
time with rtc.init() or rtc.datetime(), and reading the date and time with
rtc.datetime() or rtc.now().  The method weekday() reports the weekday of
the current date.  It starts with 0 for Monday.

The tuple order for datetime() and now() matches the CPython sequence:
(year, month, day, hour, minute, second, microsecond, TZ).  TZ is ignored
and reported as None.  Microsecond is provided at a best effort.

If a battery is not supplied, the default boot date/time is 1970/1/1 0:0:0.
With a battery, the clock continues to run even when the board is not
powered.  The clock is quite precise.  If not, using rtc.calibration() may
help.

Port of MicroPython to NXP iMX RT 10xx

Currently supports Teensy 4.0 and the i.MX RT1010 EVK board.

Features:

  • REPL over USB VCP
  • machine.Pin

Known issues:

  • pyboard.py doesn't work with files larger than 64 bytes
  • machine.Pin class currently does not support GPIOMUX option of i.MX RT101x variants

TODO:

  • Enable TCM
  • Peripherals (LED, Timers, etc)
