8be29b9b1b esp32/machine_hw_spi: Use a 2 item SPI queue for long transfers.
Using a 2-item transaction queue instead of 1 allows long transfers to 
be executed with the minimum inter-transaction delay. Limit maximum 
transaction length to ensure an integer multiple of the SPI `bits` 
setting are transferred. Fixes #7511.

eb3029c669 esp32/machine_spi: Calculate actual attained baudrate.
Calculate the actual baudrate that the hardware is capable of achieving 
and remember it so that printing the SPI object will show this. Fixes

89945b1989 esp32/machine_hw_spi: Allow None for unused pins in initializer.
Make the hardware SPI initializer method match the `init()` method by 
allowing `None` to be given for `sck`/`mosi`/`miso` to specify an unused 
signal.

71f3ade770 ports: Support legacy soft I2C/SPI construction via id=-1 arg.
With a warning that this way of constructing software I2C/SPI is
deprecated.  The check and warning will be removed in a future release.

This should help existing code to migrate to the new SoftI2C/SoftSPI types.

84fa3312cf all: Format code to add space after C++-style comment start.
Note: the uncrustify configuration is explicitly set to 'add' instead of
'force' in order not to alter the comments which use extra spaces after //
as a means of indenting text for clarity.

f301170c7c esp32/machine_hw_spi: Fix exception msg when host is already in use.
When a SPI bus is initialized with a SPI host that is currently in use the
exception msg incorrectly indicates "SPI device already in use".  The
mention of "device" in the exception msg is confusing because the error is
about trying to use a SPI host that is already claimed.  A better exception
msg is "SPI host already in use".

da72bb6833 esp32/machine_hw_spi: Make HW SPI objects statically allocated.
This aligns more closely with the hardware, that there are two, fixed HW
SPI peripherals.  And it allows to recreate the HW SPI objects without
error, as well as create them again after a soft reset.

Fixes issue #4103.

bc08c884a2 esp32: Add new port to Espressif ESP32 SoC.
This commit is a combination of 216 commits from the initial stages of
development of this port, up to and including the point where the code was
moved to the ports/esp32 directory.  These commits were mostly concerned
with setting up the build system and getting a reliable port working with
basic features.  The following is a digest of the original commits in their
original order (most recent listed first), grouped where possible per
author.  The list is here to give credit for the work and provide some
level of traceability and accountability.  For the full history of
development please consult the original repository.

All code is MIT licensed and the relevant copyright holders are listed in
the comment-header of each file.

Odd Stråbø <oddstr13@openshell.no>
  esp32: Initial working implementation of machine.UART.

  Code lineage (as seen by previous commits): I copied the ESP8266 code,
  renamed pyb -> machine, and used esp-idf as a reference while implementing
  minimal functionality.  I provide all of my changes under the MIT license.

  edited.  Total derivative work.

Andy Valencia <vandyswa@gmail.com>
  esp32: Add PWM support via machine.PWM class.

  Code lineage:
  I started by copying the esp8266 machine_pwm.c. I used information from the
  ESP32 Technical Reference Manual, the esp-idf documentation, and the SDK's
  sample ledc example code (but I did not copy that code, just studied it to
  understand the SDK's API for PWM). So aside from the code copied from the
  esp8266 PWM support, everything else you see is just new code I wrote.

  I wasn't an employee of anybody when I wrote it, and I wrote it with the
  understanding and intention that it's simply a derivative work of the
  existing micropython code. I freely and willingly contribute it to the
  project and intend that it not change the legal status of the micropython
  code base in any way, even if it is included in that base in whole or part.
