Mike Teachman 8a5bfe44a5 esp32,stm32: Add new machine.I2S class for I2S protocol support.
This commit adds I2S protocol support for the esp32 and stm32 ports, via
a new machine.I2S class.  It builds on the stm32 work of blmorris, #1361.

Features include:
- a consistent I2S API across the esp32 and stm32 ports
- I2S configurations supported:
  - master transmit and master receive
  - 16-bit and 32-bit sample sizes
  - mono and stereo formats
  - sampling frequency
  - 3 modes of operation:
    - blocking
    - non-blocking with callback
    - uasyncio
  - internal ring buffer size can be tuned
- documentation for Pyboards and esp32-based boards
- tested on the following development boards:
  - Pyboard D SF2W
  - Pyboard V1.1
  - ESP32 with SPIRAM
  - ESP32

Tim Radvan fd24e649fd docs/library: Add initial API reference for rp2 module and its classes.
All the method signatures from rp2_pio.c and friends have been taken and
converted to RST format, then explanatory notes added for each signature.

This is provide by a few ports now, and is very useful.

Damien George 9e1b25a99e docs/library/machine: Specify initial machine.PWM class.
This adds an initial specification of the machine.PWM class, to provide a
way to generate PWM output that is portable across the different ports.
Such functionality may already be available in one way or another (eg
through a Timer object), but because configuring PWM via a Timer is very
port-specific, and because it's a common thing to do, it's beneficial to
have a top-level construct for it.

The specification in this commit aims to provide core functionality in a
minimal way.  It also somewhat matches most existing ad-hoc implementations
of machine.PWM.

See discussion in #2283 and #4237.

Jason Neal 7ef2f65114 docs/library: Add / to indicate positional-only args in library docs.

look like keyword arguments.

Damien George b16146d189 docs/machine: Change sleep to lightsleep and add timeout arguments.
The machine.sleep() function can be misleading because it clashes with
time.sleep() which has quite different semantics.  So change it to
machine.lightsleep() which shows that it is closer in behaviour to
machine.deepsleep().

Also, add an optional argument to these two sleep functions to specify a
maximum time to sleep for.  This is a common operation and underlying
hardware usually has a special way of performing this operation.

The existing machine.sleep() function will remain for backwards
compatibility purposes, and it can simply be an alias for
machine.lightsleep() without arguments.  The behaviour will be the same.

Damien George 81e320aecc docs/library/machine: Remove conditionals in machine class index.
The machine module should be standard across all ports so should have the
same set of classes in the docs.  A special warning is added to the top of
the machine.SD class because it is not standardised and only available on
the cc3200 port.

things, then everything else.

Damien George 0c821f7def docs/library/machine: Make separate TOC for WiPy vs non-WiPy.
WiPy is the only port with ADC and SD, so they shouldn't be included in
other ports' documentation.

Paul Sokolovsky d5e9ab6e61 extmod/machine_pulse: Make time_pulse_us() not throw exceptions.
machine.time_pulse_us() is intended to provide very fine timing, including
while working with signal bursts, where each transition is tracked in row.
Throwing and handling an exception may take too much time and "signal loss".
So instead, in case of a timeout, just return negative value. Cases of
timeout while waiting for initial signal stabilization, and during actual
timing, are recognized.

The documentation is updated accordingly, and rewritten somewhat to clarify
the function behavior.

Damien George f3b5480be7 stmhal,cc3200,esp8266: Consistently use PWRON_RESET constant.
machine.POWER_ON is renamed to machine.PWRON_RESET to match other
reset-cause constants that all end in _RESET.  The cc3200 port keeps a
legacy definition of POWER_ON for backwards compatibility.
