iabdalkader 71afed1a70 stm32/mphalport: Fix I/O glitches when switching GPIO mode to alt-func.
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.

Martin Fischer 5873390226 rp2/mphalport: Fix USB CDC RX handling to not block when unprocessed.
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.

iabdalkader 5562ed3f43 stm32/pyb_can: Replace CAN.initfilterbanks with CAN.init keyword arg.
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.

iabdalkader e7264e9532 stm32/pyb_can: Add support for bus with mixed Classic/FD nodes.
A CAN bus can have mixed classic/FD nodes.  Prior to this patch the CAN API

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.

Also document this function and explain how to use this in quickref to
retain pin configuration during deep-sleep.

Jonathan Hogg 7684c996bc esp32/machine_pin: Add new hold keyword argument and remove PULL_HOLD.
The current pull=Pin.PULL_HOLD argument doesn't make a lot of sense in the
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.

Fixes issue #8283, and see also #8284.

Damien George 2b409ef8a4 unix/moduos: Convert module to use extmod version.
All variants now use extmod/moduos.c as their uos module implementation.
In particular this means they all have MICROPY_VFS enabled and use VfsPosix
for their filesystem.

As part of this, the available functions in uos become more consistent with
other ports:
- coverage variant gets uos.urandom
- minimal and standard variant get: unlink, chdir, getcwd, listdir

robert-hh e0b97013d0 mimxrt/hal/pwm_backport: Make PWM symmetric, and round division calcs.
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.
