The MP_OBJ_STOP_ITERATION optimisation is a shortcut for creating a
StopIteration() exception object, and means that heap memory does not need
to be allocated for the exception (in cases where it can be used). This
commit allows this optimised object to take an optional argument (before,
it could only have no argument).
The commit also adds some new tests to cover corner cases with
StopIteration and generators that previously did not work.

MicroPython implements some 3.5+ features, and this change helps to reduce
the need for some .exp files in the test suite.

This commit moves all first-party code developed for this project from lib/
to shared/, so that lib/ now only contains third-party code.
The following directories are moved as-is from lib to shared:
lib/libc -> shared/libc
lib/memzip -> shared/memzip
lib/netutils -> shared/netutils
lib/timeutils -> shared/timeutils
lib/upytesthelper -> shared/upytesthelper
All files in lib/embed/ have been moved to shared/libc/.
lib/mp-readline has been moved to shared/readline.
lib/utils has been moved to shared/runtime, with the exception of
lib/utils/printf.c which has been moved to shared/libc/printf.c.

To reduce the number of calls to mp_hal_stdout_tx_strn and improve the
overall throughput of printing data. This implementation is taken from
ports/stm32/mphalport.c.

For some boards, even -fm dio is too fast and they require -fm dout. This
commit links to the esptool wiki about available flash modes and changes
dio to dout.
This test snuck through without proper formatting and is causing CI for
other unrelated changes to fail.

This adds the --tags argument to the git describe command that is used
to define the MICROPY_GIT_TAG macro. This makes it match non-annotated
tags. This is useful for MicroPython derivatives that don't use
annotated tags.

Adds support for hardware SPI to the zephyr port. Consistent with other
ports, such as rp2 and stm32, we only implement the SPI protocol functions
(init and transfer). Explicit sck/mosi/miso selection is not supported
and new SPI instances are initialized with default values.
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

These warnings appear with GCC 11. Keep them as warnings but not as
compiler errors so they can be dealt with properly in the future.

The ADC_FIRST_GPIO_CHANNEL and ADC_LAST_GPIO_CHANNEL macros are no longer
needed. Instead the pin_adcX table (X = 1, 2, 3) is now generated to be
the exact size needed for a given MCU, and MP_ARRAY_SIZE(pin_adcX) is used
to determine the upper bound.
This commit also allows CPU pins to be excluded from ADC configuration if
they are hidden by prefixing their name with a "-".

* Modify common functions in adc.c to accept ADC handle.
* Most external channels are connected to ADC12 which is used by default.
* For ADCAll (internal channels) ADC3 is used instead.
* Issue #4435 is possibly related (at least partially fixed).
Add new API for specifying the idle level and TX carrier output level, and
new write_pulses modes of operation. Also fix wait_done documentation
which was inverted and wrong about timing.
This change allows specification of the idle level and TX carrier output
level (through changed initialisation API), and more flexible specification
of pulses for write_pulses.
This is a breaking change for the esp32.RMT constructor API. Previous code
of this form:
esp32.RMT(..., carrier_duty_percent=D, carrier_freq=F)
will now raise an exception and should be changed to:
esp32.RMT(..., tx_carrier=(F, D, 1))
The firmware for Teensy 4.0, Teensy 4.1 and MIMXRT1020_EVK are created.
Users of other MIMXRT10xx_EVK boards should be able to build the firmware
themselves, they might need specific DEBUG settings.
The Makefile had to be changed in order to build the .bin file as well.
This adds a call to mp_deinit() in the main function of the STM32 port.
This enables the use of MICROPY_PORT_DEINIT_FUNC on that port, as well as
cleaning up the GIL if threading is enabled.
Previous behaviour was: if boot.py had an exception then main.py would
still run, which is arguably unexpected behaviour.
This commit changes the behaviour so main.py is not run if boot.py has an
error.
