Prior to this commit, the pin defined for power would be used by the
esp_idf driver to reset the PHY. That worked, but sometimes the MDIO
configuration started before the power was fully settled, leading to an
error.
With the change in this commit, the power for the PHY is independently
enabled in network_lan.c with a 100ms delay to allow the power to settle.
A separate define for a reset pin is provided, even if the PHY reset
pin is rarely connected.
Fixes issue #14013.

On these targets it's possible to enter the bootloader by setting a bit in
an RTC register before resetting.
Structure it in a way that a board can still provide a custom bootloader
handler. The handler here will be the default if none is provided, for any
board based on the supported targets.

Currently only the Arduino Nano ESP32 defines a machine.bootloader handler
for ESP32. All other boards will intentionally hang.
There is no error message, nor is a NotImplementedError raised. There's no
indication if Micropython has crashed, or if the bootloader was entered but
USB is not working, which is a real problem the ESP32 bootloader has. It's
not possible escape from this hang with ^C or any other means besides
physical access to the reset pin or the ability to cycle power.
Change this to only define an implementation of machine.bootloader() when
there is a handler for it.

The new IDF v5.2 deprecated the task cleanup callback we use, so support
for the new option has been implemented in the previous commit. This also
requires a change in the sdkconfig, via a new variable
${SDKCONFIG_IDF_VERSION_SPECIFIC} which is used in all mpconfigboard.cmake
files to include an extra sdkconfig file based on the IDF version in use.

The legacy I2S "shim" is removed and replaced by the new I2S driver. The
new driver fixes a bug where mono audio plays only in one channel.
Application code size is reduced by 2672 bytes with this change. Tested on
ESP32, ESP32+spiram, ESP32-S3 using example code from

Adds Dx and Ax named pins for Arduino Gigi, Arduino Nicla Vision and
Arduino Portenta H7. The analog pins include the dual-pad _C pins.
Signed-off-by: Sebastian Romero <s.romero@arduino.cc>

This commit adds support for the dual-analog-pads on STM32H7 parts. These
pads/pins are called PA0_C/PA1_C/PC2_C/PC3_C in the datasheet. They each
have an analog switch that can optionally connect them to their normal pin
(eg PA0). When the switch is open, the normal and _C pin are independent
pins/pads.
The approach taken in this commit to make these _C pins available to Python
is:
- put them in their own, independent row in the stm32h7_af.csv definition
file, with only the ADC column defined (they are separate machine.Pin
entities, and doing it this way keeps make-pins.py pretty clean)
- allow a board to reference these pins in the board's pins.csv file by the
name PA0_C etc (so a board can alias them, for example)
- these pins (when enabled in pins.csv) now become available like any other
machine.Pin through both machine.Pin.board and machine.Pin.cpu
- BUT these _C pins have a separate pin type which doesn't have any
methods, because they don't have any functionality
- these _C pins can be used with machine.ADC to construct the appropriate
ADC object, either by passing the string as machine.ADC("PA0_C") or by
passing the object as machine.ADC(machine.Pin.cpu.PA0_C)
- if a board defines both the normal and _C pin (eg both PA0 and PA0_C) in
pins.csv then it must not define the analog switch to be closed (this is
a sanity check for the build, because it doesn't make sense to close the
switch and have two separate pins)

This new DMA API corrects possible cache coherency issues on chips with
D-Cache, when working with buffers at arbitrary memory locations (i.e.
supplied by Python code).
The API is used by SPI to fix an issue with corrupt data when reading from
SPI using DMA in certain cases. A regression test is included (it depends
on external hardware connection).
Explanation:
1) It's necessary to invalidate D-Cache after a DMA RX operation completes
in case the CPU reads (or speculatively reads) from the DMA RX region
during the operation. This seems to have been the root cause of issue
#13471 (only when src==dest for this case).
2) More generally, it is also necessary to temporarily mark the first and
last cache lines of a DMA RX operation as "uncached", in case the DMA
buffer shares this cache line with unrelated data. The CPU could
otherwise write the other data at any time during the DMA operation (for
example from an interrupt handler), creating a dirty cache line that's
inconsistent with the DMA result.
Fixes issue #13471.

symbols PHY_LAN8720, PHY_LAN8742, PHY_DP83825 and PHY_DP8348. The default

The STATIC macro was introduced a very long time ago in commit
d5df6cd44a433d6253a61cb0f987835fbc06b2de. The original reason for this was
to have the option to define it to nothing so that all static functions
become global functions and therefore visible to certain debug tools, so
one could do function size comparison and other things.
This STATIC feature is rarely (if ever) used. And with the use of LTO and
heavy inline optimisation, analysing the size of individual functions when
they are not static is not a good representation of the size of code when
fully optimised.
So the macro does not have much use and it's simpler to just remove it.
Then you know exactly what it's doing. For example, newcomers don't have
to learn what the STATIC macro is and why it exists. Reading the code is
also less "loud" with a lowercase static.
One other minor point in favour of removing it, is that it stops bugs with
`STATIC inline`, which should always be `static inline`.
Methodology for this commit was:
1) git ls-files | egrep '\.[ch]$' | \
xargs sed -Ei "s/(^| )STATIC($| )/\1static\2/"
2) Do some manual cleanup in the diff by searching for the word STATIC in
comments and changing those back.
3) "git-grep STATIC docs/", manually fixed those cases.
4) "rg -t python STATIC", manually fixed codegen lines that used STATIC.

This sets the BLE key distribution parameters at runtime. This isn't
needed in most ports since we already set the default values in
`extmod/nimble/syscfg/syscfg.h`; however in the ESP32 port that
headerfile is not used, and the default values in the ESP-IDF don't
enable key distribution nor can we change those defaults via
`sdkconfig`. Thus we're setting these values explicitly at runtime.

This moves the runtime initialisation of `ble_hs_cfg` to happen after
`nimble_port_init()`. That is consistent with the order used in NimBLE
examples. On the ESP32 port this is needed because the ESP-IDF sets up
the default RAM secret store callbacks in its implementation of
`nimble_port_init()` (specifically, it calls `esp_nimble_init()` which
in turn calls `ble_store_ram_init()`). We want to override those with
our own callbacks to implement the `IRQ_[GS]ET_SECRET` events in Python.

When the websocket closes currently, it does not send a proper

This combines the argument parsing and checking for the machine.SPI.init()
and machine.SPI() interfaces.
The only real difference was unspecified arguments in init() mean to keep
the same value, while in new they get default values.
Behavior has changed for passing the "id" argument to init(). On other
ports this isn't allowed. But on esp32 it would change the SPI controller
of the static SPI instance to the new id. This results in multiple static
spi objects for the same controller and they would fight over which one has
inconsistent mpy vs esp-idf state. This has been changed to not allow "id"
with init(), like other ports.
In a few causes, a loop is used over arguments that are handled the same
way instead of cut & pasting the same stanza of code for each argument.
The init_internal function had a lot of arguments, which is not efficient
to pass. Pass the args mp_arg_val_t array instead as a single argument.
This reduced both the number of C lines and the compiled code size.
Summary of code size change: Two argument lists of 72 bytes are replaced
by a single shared 72 byte list. New shared argument parsing code is small
enough to be inlined, but is still efficient enough to shrink the overall
code size by 349 bytes of the three argument handlering functions.
