Dryw Wade f456a23b62 esp32/machine_pin: Make all pins on ESP32-P4 output capable.
All GPIO pins on the ESP32-P4 are output capable, so there is no need to
define GPIO_FIRST_NON_OUTPUT.

Fixes #18982.

Alessandro Gatti 2f16bf430a esp32/network_wlan: Look up IP addresses for the stations list.
This commit extends the output of `WLAN.status('stations')` to also
include the IP address of WiFi stations connected to the device if in AP
mode.

IP address lookup is currently not available on targets that use hosted
WiFi (eg. ESP32P4), as the hosted API does not yet support performing
the MAC->IP lookup on the WiFi MCU end.

The ESP32 port is brought up to parity with most ports in this regard
(primarily with the ESP8266).  This functionality depends on the DHCP
server provided by ESP-IDF, which is automatically run on the WiFi
interface if the device is put in AP mode.  Currently the ESP32 port
cannot run with said DHCP server disabled, so if a device does not
request a static IP it may either have the wrong IP address returned
(since the DHCP server assigned an address which is then discarded by
the client), or it won't have any (ie. "0.0.0.0").  In the latter case
`None` will be returned as the station's address instead.

This implements #9203.

Dryw Wade e57e522182 esp32/machine_sdcard: Make default SDMMC slot configurable.
Resolves part of #18984.  On ESP32-P4, SDMMC slot 0 supports SDIO 3.0, and
is liekly the default for most boards.  MICROPY_HW_SDMMC_DEFAULT_SLOT can
be set in `mpconfigboard.h` to change default slot.

Alessandro Gatti 024178455d unix/modsocket: Add "sendall" method to socket class.
This commit adds an implementation for "socket.sendall" to the Unix
port.

Right now the implementation is a wrapper over a single "socket.send"
call, since it wasn't possible to let "socket.send" perform a partial
transfer.  With no partial transfers it is not possible to have a
testable implementation following the expected behaviour, so a single
send operation is done and OSErr(EINTR) is raised if a partial transfer
occurs.

The discussion for the issue linked to this PR contains more information
about the efforts made to let partial transfers happen.

This fixes #16803.

Kwabena W. Agyeman 501b0e6bab alif/tinyusb_port: Fix _xfer_trb cache alignment.
TRB buffers, which are the target of cache clean/invalidate actions, were
not cache-aligned between buffers.  Reported the problem to Alif, and
adding padding to them is the proper fix.  Appears to work without any
other changes in device behavior.

On the esp32 port when adding a user C module, the source code for the user
C module was being compiled without certain C flags.  Notably the
optimisation flag was missing.

This commit fixes that by explicitly adding the missing C flags to the
compilation of user C modules.

The missing flags were the following, which are now included when building
user C modules (found by inspecting the generated CMake files when building
with ulab):

    -ffunction-sections
    -fdata-sections
    -Wall
    -Werror=all
    -Wno-error=unused-function
    -Wno-error=unused-variable
    -Wno-error=unused-but-set-variable
    -Wno-error=deprecated-declarations
    -Wextra
    -Wno-error=extra
    -Wno-unused-parameter
    -Wno-sign-compare
    -Wno-enum-conversion
    -gdwarf-4
    -ggdb
    -mdisable-hardware-atomics
    -O2
    -fmacro-prefix-map=micropython/ports/esp32=.
    -fmacro-prefix-map=espressif/esp-idf=/IDF
    -fstrict-volatile-bitfields
    -fno-jump-tables
    -fno-tree-switch-conversion

that garbage collection only happens when Python execution finishes and

The `tests/ports/webassembly/heap_expand.py` expected output also needs to

Alessandro Gatti b3d88cf210 extmod/nimble/modbluetooth_nimble: Handle port init failures.
This commit fixes an issue related to the NimBLE initialisation
procedure in low memory environments on ESP32 boards.

MicroPython uses at least two different NimBLE stacks across the
supported ports, mynewt (imported as an external library), and the one
provided by Espressif in their own SDKs.  The problem is that these two
ports differ in the signature for `nimble_port_init(void)`, with mynewt
returning `void`, and Espressif's returning a status code on failure.

On ESP32 boards, allocating almost all the available heap and then
turning on the Bluetooth stack would trigger a failure in the NimBLE
initialisation function that is not handled by the NimBLE integration
code, as there's no expectation of a recoverable condition.  Since the
stack initialisation would progress, then uninitialised memory accesses
crash the board.

Since we cannot really modify neither mynewt nor Espressif SDKs, the
next best thing is to provide two conditional initialisation paths
depending on a configuration setting.  This would make Espressif ports
recover from a failed initialisation whilst retaining the existing
behaviour on other ports.

This fixes #14293.

Damien George 094c268ff1 stm32/machine_pwm: Use heuristic to assign TIMx_CHy to a pin.
When assigning a TIMx_CHy to a pin, the second available alternate function
is chosen (or the first if there is only one).  This gives better overall
static allocation of TIM's to pins.

On most MCUs (eg F4, F7, H5, H7) picking the second gives TIM5_CH[1-4] for
PA0-PA3, and TIM5 is a 32-bit timer.  That leaves TIM2 (also usually on
PA0-PA3) for other pins that only have TIM2.

For STM32G0, STM32L432 and STM32L452 the heuristic is to simply use the
first available alternate function because that gives TIM2 (a 32-bit timer)
on PA0-PA3.

The above heuristic guarantees that PA0-PA3 always get a 32-bit timer on
all supported MCUs.

Damien George dbe6a11670 stm32/machine_pwm: Implement machine.PWM class.
This commit implements the standard `machine.PWM` class on stm32, using the
common bindings in `extmod/machine_pwm.c`.  Features implemented are:
- construct a PWM object from a pin, with automatic selection of TIM
  instance and channel;
- get and set freq, duty_u16 and duty_ns;
- optionally invert the output.

The PWM objects are static objects (partly in ROM, partly in RAM) so
creating a PWM instance on the same pin will return exactly the same
object.  That's consistent with other peripherals in the stm32 port, and
consistent with other PWM implementations (eg rp2).

When creating a PWM object on a pin, if that pin has multiple TIM instances
then only the first will be selected.  A future extension could allow
selecting the TIM/channel (eg similar to how ADCBlock allows selecting an
ADC).

Implemented according to API docs in a parent comment.

Adds new multi_extmod/machine_can_* tests which pass when testing between
NUCLEO_G474RE, NUCLEO_H723ZG and PYBDV11.

Angus Gratton 6f835b365a stm32: Implement index-aware STM32G4 FDCAN HAL TX functions.
These are oddly missing from the STM32G4 HAL, but the
reference manual describes being able to use them and
the implementations seem to work as expected.

Note that unlike STM32H7 it doesn't seem like we must use this approach,
because HAL_FDCAN_AddMessageToTxFifoQ() does seem to not have the issues
with priority inversion seen on the H7. However it's simpler to use the
same API for both...

Angus Gratton cda49bed27 py/objlist,stm32,esp32: Add helpers for creating/ensuring list args.
Simplifies the pattern of an optional arg which can be a list of at

Modify pyb.CAN and ESP-NOW APIs to use the helper. Note this changes
the return type of pyb.CAN.recv() from tuple to list.
