By comparing the address of the initial 'name' field instead of the
addresses of the objects themselves, a small amount of type safety is
added back, vs just casting to void.
In the event that some other kind of object is passed in as 't',
which happens to have a 'name' field of the right type, the construct
would be (undesirably) accepted but it would almost certainly evaluate
to false at runtime.
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).
