The nxp_driver v2.10 allows for/requires some changes to the code:
- Remove some part of pwm_backlog.*, which is provided by the lib now.
- Change eth.c: the newer versions have additional parameters of the
library versions.
- Change sdcard.c: use TransferBlocking instead of TransferNonblocking.
- Add some support for the MIMXRT1176 device.
- Set the clocks for UART, I2C, Timer.
- Integrate the I2S module and fix a rebase error.
- Use blocking transfer only for SPI. It's faster and interferes less with
other modules.
- Use the clock_config.c files of library v2.8.5. The mimxrt files keeps
the clock_config.c files from Verson 2.8.5. With clock_config.c from
v2.10, the boards do not work. Refactoring of the clock set-up is on the
to-do list.
- Enable expiry timers for UART, I2C and SPI, avoiding a stall in library
code.
- The clock_config.* files are moved from the board-specific directories to
the boards directory and given a MCU related name.
It's no longer needed because this macro is now processed after
preprocessing the source code via cpp (in the qstr extraction stage), which
means unused MP_REGISTER_MODULE's are filtered out by the preprocessor.

This cleans up the parsing of MP_REGISTER_MODULE() and generation of
genhdr/moduledefs.h so that it uses the same process as compressed error
string messages, using the output of qstr extraction.
This makes sure all MP_REGISTER_MODULE()'s that are part of the build are
correctly picked up. Previously the extraction would miss some (eg if you
had a mod.c file in the board directory for an stm32 board).
Build speed is more or less unchanged.

For ports with MICROPY_VFS and MICROPY_PY_IO enabled their configuration
can now be simplified to use the defaults for mp_import_stat and
mp_builtin_open.
This commit makes no functional change, except for the following minor
points:
- the built-in "open" is removed from the minimal port (it previously did
nothing)
- the duplicate built-in "input" is removed from the esp32 port
- qemu-arm now delegates to VFS import/open

The following changes are made:
- If MICROPY_VFS is enabled then mp_vfs_import_stat and mp_vfs_open are

- If MICROPY_PY_IO is enabled then "open" is automatically included in the
set of builtins, and points to mp_builtin_open_obj.
This helps to clean up and simplify the most common port configuration.

Reasons for removal:
- It did not work properly because it stopped the hardware watchdog

- "The watchdog is not intended to be stopped. That is a feature."

Replace the timer-based sleep with the standard win32 call since the former
has no benefits: even though it allows specifying the time in 100uSec
chunks, the actual resolution is still limited by the OS and is never
better than 1mSec.
For clarity move all of this next to the mp_hal_delay_ms definition so all
related functions are in one place.
This replaces occurences of

foo->base.type = &foo_type;
with

Excludes any places where base is a sub-field or when new0/memset is used.

To avoid any I/O glitches in mp_hal_pin_config, make sure a valid alternate
function is set in AFR first before switching the pin mode. When switching
from AF to INPUT or OUTPUT, the AF in AFR will remain valid up until the
pin mode is switched.
On ESP32 S2/S3 variants, GPIO0 through GPIO21 are valid RTC pins. This
commit defines the valid RTC_VALID_EXT_PINS for the S2/S3 variants,
otherwise, it keeps functionality the same.
For ESP32-S3 configurations, CONFIG_SPIRAM_MODE_OCT requires pins 33-37 for
PSRAM. So exclude them from the machine_pin_type and machine_pin_irq_type
object tables.
These boards do not build with IDF v4.4 because the section .iram0.text

Prior to this commit, the USB CDC OUT endpoint got NACK'd if a character
was received but not consumed by the application, e.g. via
sys.stdin.read(). This meant that USB CDC was blocked and no additional
characters could be sent from the host. In particular a ctrl-C could not
interrupt the application if another character was pending.
To fix the issue, the approach in this commit uses a callback tud_cdc_rx_cb
which is called by the TinyUSB stack on reception of new CDC data. By
consuming the data immediately, the endpoint does not stall anymore. The
previous handler tud_cdc_rx_wanted_cb was made obsolete and removed.
In addition some cleanup was done along the way: by adding interrupt_char.c
and removing the existing code mp_hal_set_interrupt_char(). Also, there is
now only one (stdin) ringbuffer.
Fixes issue #7996.
The CAN.initfilterbanks() class method is removed, and its functionality is
replaced with the "num_filter_banks" keyword argument to the CAN
constructor and CAN.init(). This configures the filter bank split.
This new approach provides more flexibility configuring the resources used
by a given CAN instance, allowing other MCUs like H7 to fit the API. It
also brings CAN closer to how other machine peripherals are configured,
where everything is done in the constructor/init method.
This is a breaking change to the CAN API.
CAN.recv() now returns a 5-tuple, with the new element in the second
position being a boolean, True if the ID is extended.
This is a breaking change of the API for CAN.recv().
A CAN bus can have mixed classic/FD nodes. Prior to this patch the CAN API
could be configured for either standard or extended ID, but not both/mixed
operation.
This patch allows extended IDs to be filtered and enabled on a per-message
basis, in send(), setfilter() and clearfilter().
This is a breaking change to the API: init() no longer accepts the extframe
keyword argument.
- Enable CAN FD frame support and BRS.
- Optimize the message RAM usage per FDCAN instance.
- Document the usage and different sections of the Message RAM.
This commit adds support for machine.I2S on the mimxrt port. The I2S API

Add a new function to control whether held pins will retain their function

context of what it actually does vs what the ESP32 quickref document says
it does.
This commit removes PULL_HOLD and adds a new hold=True|False keyword
argument to Pin()/Pin.init(). Setting this to True will cause the ESP32 to
lock the configuration of the pin – including direction, output value,
drive strength, pull-up/-down – such that it can't be accidentally changed
and will be retained through a watchdog or internal reset.

Ensure the symmetry of PWM: the duty rate of X and Q channels was not 50%,
when it should have been. That is evident at high frequencies, like 15Mhz
or 37.5 MHz. At low frequencies the deviation mattered less. The A/B
channels were fine.
Also round up or down non-integer division factors. Before, always the
floor value was used.
That caused Ethernet to lock up at high data rates after ~200MByte data
average in a row. Tested now with data bursts up to 10 GByte and overall
data rates of ~8MByte/s at the Eth100 port.
Sometimes frames could not be sent immediately because the controller was
still busy with previous frames. Then, an error was returned to lwip.
This fix adds a limited number of retries for this busy state, waiting
100µs before the next attempt. Typically the transmit succeeds now at the
second attempt.
Second change: Reset the controller for a clean state after soft reset.

If MicroPython threads are enabled, loops waiting for an incoming event
should release the GIL and suspend, allowing other tasks to run while they
wait.
Prior to this commit, the problem can easily be observed by running a
thread that is both busy and regularly releases the GIL (for example a loop
doing something then sleeping a few ms after each iteration). When the
main task is at the REPL, the thread is significantly stalled. If the main
task is manually made to release the GIL (for example, by calling
utime.sleep_ms(500)) the other thread can be seen immediately working at
the expected speed again.
Additionally, there are various instances in where blocking functions run
MICROPY_EVENT_POLL_HOOK in a loop while they wait for a certain event/
condition. For example the uselect methods poll objects to determine
whether data is available, but uses 100% of CPU while it does, constantly
calling MICROPY_EVENT_POLL_HOOK in the process.
The MICROPY_EVENT_POLL_HOOK macro is only ever used in waiting loops, where
(if threads are enabled) it makes sense to yield for a single tick so that
these loops do not consume all CPU cycles but instead other threads may
execute. (In fact, the thing these loops wait for may even indirectly or
directly depend on another task being able to run.)
This change moves the sleep that was inside the REPL input function to
inside the MICROPY_EVENT_POLL_HOOK macro, where the GIL is already being
released, solving both the blocking REPL issue and the 100% CPU use issue
at the same time.
