Victor Rajewski 730525cec9 stm32/qspi: Allow qspi_write_cmd_data to write cmd with 1 data byte.
The existing qspi for stm32 implementation can only send a spi command with
exactly 0 or 2 data bytes.  Certain spiflash chips (e.g. AT25SF321B) have
commands that only take a single data byte, and will ignore the command if
more than that is sent.  This commit allows sending a command with a single
data byte.

Yuuki NAGAO cb38f77918 stm32/adc: Add workaround for ADC errata with G4 MCUs.
For STM32G4, there is a errata on ADC that may get wrong ADC result.
According to the errata sheet, this can be avoid by performing two
consecutive ADC conversions and keep second result.

Yuuki NAGAO d9764ad140 stm32/adc: Fix reading internal ADC channels on G4 MCUs.
For STM32G4 series, the internal sensors are connected to:
- ADC1_IN16: Temperature sensor
- ADC1_IN17: Battery voltage monitoring
- ADC1_IN18: Internal voltage reference
but ADC_CHANNEL_TEMPSENSOR_ADC1, ADC_CHANNEL_VBAT,
ADC_CHANNEL_VREFINT are not defined as 16, 17, 18.

This commit converts channel 16, 17, 18 to ADC_CHANNEL_x in

Yuuki NAGAO de8035b510 stm32/adc: Fix ADC clock prescaler for G4 MCUs.
For STM32G4, ADC clock frequency should be equal or less than 60MHz.
To satisfy this specification, ADC clock prescaler should be equal or
greater than 4 (For example, NUCLEO_G474RE runs 170MHz).

In addition, to obtain accurate internal channel value,
the ADC clock prescaler is set to 16 because vbat needs at least 12us
(16/170*247.5=23.3us).

Yuuki NAGAO ec9ea97413 stm32/dac: Fix dac.write_timed on G4 MCUs to use 32-bit DMA access.
For STMG4 MCUs, the peripheral registers for DAC have to be accessed by
words (32bits) because DAC is connected to AHB directly.

(This requirement is also there for other MCU series.  However, if DAC is
connected to APB like F4/L1/L4 MCUs, AHB byte or half-word transfer is
changed into a 32-bit APB transfer.  This means that PSIZE does not have to
be DMA_PDATAALIGN_WORD on these MCUs, and in fact must be BYTE/HALFWORD to
function correctly.)

Fixes issue #9563.

Glenn Moloney dbced75b48 esp32/network_wlan: Wait for STA/AP START/STOP event in wlan.active.
This is a fix for commit bccbaa92b1fc6237f0f49a7f07cc194835fbf4e3:
- Should only wait for WIFI_EVENT_STA_START when invoked on the STA_IF
  interface.
- The WIFI_EVENT_STA_START event is generated every time the STA_IF
  interface is set active(True) and it was previously inactive, ie. not
  only after calling esp_wifi_start().
- Also wait for WIFI_EVENT_STA_STOP when deactivating the interface.
- Also wait for relevant AP events.

This commit updates the esp32 port to work exclusively with ESP-IDF v5.
IDF v5 is needed for some of the newer ESP32 SoCs to work, and it also

Brian 'redbeard' Harrington 5fe2a3f14f esp32/CMake: Change PROJECT_DIR to CMAKE_CURRENT_LIST_DIR.
This migrates the CMake variable `MICROPY_PORT_DIR` from the ESP-IDF
defined project to the component. Previously used instances of the variable
within the project definition have been migrated to
`CMAKE_CURRENT_LIST_DIR`. Within the component (the `main` subdirectory in
the ESP32 port) we define `MICROPY_PORT_DIR` using `CMAKE_CURRENT_LIST_DIR`
and subsequently use the `MICROPY_PORT_DIR` value in all locations where
`PROJECT` had previously been used.

Context:

In commit 9b90882146, initial support was added for building with the newly
introduced CMake support provided by the ESP-IDF.

Specifically, the commit message states:

> This commit adds support for building the esp32 port with CMake, and in
particular, it builds MicroPython as a component within the ESP-IDF. Using
CMake and the ESP-IDF build infrastructure makes it much easier to maintain
the port, especially with the various new ESP32 MCUs and their required
toolchains.

`PROJECT_DIR` is a variable populated by the ESP-IDF specifically and is
not stable when used with "[Pure CMake components][1]" as documented in the
ESP-IDF. It is intended to be used in the scope of the parent of the
current file (the "project") as opposed to the current file ("the
component"). Crossing into the parent scope like this works solely when the
"project" is MicroPython, but not when used as a component by other ESP-IDF
projects.

Analyzing this file, the intention is to reference the "Project" which in
the example is the parent directory. Within the [CMake variables][2]
documentation, there is one specifically defined for referencing the
directory for the CMake listfile currently being processed:
[`CMAKE_CURRENT_LIST_DIR`][3].

After making the change from `PROJECT_DIR` to `CMAKE_CURRENT_LIST_DIR`, the
reach into the parent scope defined by the ESP-IDF and the resulting CMake
interface violation is removed.

Similar to the component definition, the project `CMakeLists.txt` uses the
variable `CMAKE_SOURCE_DIR` which CMake defines as "The path to the top
level of the source tree."  This commit changes the variable to
`CMAKE_CURRENT_LIST_DIR` for the reasons cited above.

Jim Mussared 5e50975a6d py/modsys: Allow sys.path to be assigned to.
Previously sys.path could be modified by append/pop or slice assignment.

This allows `sys.path = [...]`, which can be simpler in many cases, but
also improves CPython compatibility.

It also allows sys.path to be set to a tuple which means that you can
clear sys.path (e.g. temporarily) with no allocations.

This also makes sys.path (and sys.argv for consistency) able to be disabled
via mpconfig. The unix port (and upytesthelper) require them, so they
explicitly verify that they're enabled.

Jim Mussared 525557738c py/builtinimport: Optimise sub-package loading.
This makes it so that sub-packages are resolved relative to their parent's
`__path__`, rather than re-resolving each parent's filesystem path.

The previous behavior was that `import foo.bar` would first re-search
`sys.path` for `foo`, then use the resulting path to find `bar`.

For already-loaded and u-prefixed modules, because we no longer need to
build the path from level to level, we no longer unnecessarily search
the filesystem. This should improve startup time.

Explicitly makes the resolving process clear:
 - Loaded modules are returned immediately without touching the filesystem.
 - Exact-match of builtins are also returned immediately.
 - Then the filesystem search happens.
 - If that fails, then the weak-link handling is applied.

This maintains the existing behavior: if a user writes `import time` they
will get time.py if it exits, otherwise the built-in utime. Whereas `import
utime` will always return the built-in.

This also fixes a regression from a7fa18c203
where we search the filesystem for built-ins. It is now only possible to
override u-prefixed builtins. This will remove a lot of filesystem stats
at startup, as micropython-specific modules (e.g. `pyb`) will no longer
attempt to look at the filesystem.

Added several improvements to the comments and some minor renaming and
refactoring to make it clearer how the import mechanism works. Overall
code size diff is +56 bytes on STM32.
