Angus Gratton fe32e1d3a1 esp32: Drop support for ESP-IDF <v5.3.
Not currently building, and too many versions to concurrently support.

Angus Gratton 82c6b0e594 esp32: Only check the lockfile currently used by the build.
Small tweak to avoid changes in other targets' lockfiles from printing
warnings when building esp32 port.

Angus Gratton d2cda57e9d rp2/rp2_dma: Disable DMA IRQ before clearing handler function.
Both the overall IRQ line and the per-channel IRQ, for good measure.

Otherwise, soft reset will remove the handler before the finaliser for the
DMA object(s) run and trigger IRQs if the channel is still active.

Closes #18765

Angus Gratton 06dbc1f486 github: Revert "Run esp32&zephyr daily to keep mstr branch caches hot".
This reverts commit 046013a1ff.

Looks like since the latest round of GitHub Actions updates, the
Cache LRU algorithm is working as designed again.

This commit updates the documentation for the `re` library, officially
documenting non-capturing grouping rules (ie. "(?:...)").

The documentation mistakenly marked that feature as not supported, but
is is indeed supported in the current iteration of the regex library.

This closes #18900.

Andrew Leech 43199278eb tests/run-tests.py: Ignore known-flaky test failures.
Reclassify failures of tests listed in flaky_tests_to_ignore as "ignored"
instead of retrying them. Ignored tests still run and their output is
reported, but they don't affect the exit code. The ci.sh --exclude lists
for these tests are removed so they run normally.

Damien George d4751a164e py: Add support for PEP 750's t-strings.
This commit adds support for t-strings by leveraging the existing f-string
parser in the lexer.  It includes:
- t-string parsing in `py/lexer.c`
- new built-in `__template__()` function to construct t-string objects
- new built-in `Template` and `Interpolation` classes which implement all
  the functionality from PEP 750
- new built-in `string` module with `templatelib` sub-module, which
  contains the classes `Template` and `Interpolation`

The way the t-string parser works is that an input t-string like:

    t"hello {name:5}"

is converted character-by-character by the lexer/tokenizer to:

    __template__(("hello ", "",), name, "name", None, "5")

For reference, if it were an f-string it would be converted to:

    "hello {:5}".format(name)

Some properties of this implementation:
- it's enabled by default at the full feature level,
  MICROPY_CONFIG_ROM_LEVEL_AT_LEAST_FULL_FEATURES
- when enabled on a Cortex-M bare-metal port it costs about +3000 bytes
- there are no limits on the size or complexity of t-strings, and it allows
  arbitrary levels of nesting of f-strings and t-strings (up to the memory
  available to the compiler)
- the 'a' (ascii) conversion specifier is not supported (MicroPython does
  not have the built-in `ascii` function)
- space after conversion specifier, eg t"{x!r :10}", is not supported
- arguments to `__template__` and `Interpolation` are not fully validated
  (it's not necessary, it won't crash if the wrong arguments are passed in)

Otherwise the implementation here matches CPython.

robert-hh 61bbd78eba mimxrt: Implement Quadrature Encoder and Counter classes.
These classes are based on the Quadrature Encoder blocks of the i.MXRT
MCUs.  The i.MXRT 102x has two encoders, the other ones four.  The i.MXRT
101x does not support this function.  It is implemented as two classes,
Encoder and Counter.

The number of pins that can be uses as inputs is limited by the MCU
architecture and the board schematics.  The Encoder class supports:
- Defining the module.
- Defining the input pins.
- Defining a pin for an index signal.
- Defining a pin for a reset signal.
- Defining an output pin showing the compare match signal.
- Setting the number of cycles per revolution (min/max).
- Setting the initial value for the position.
- Setting the counting direction.
- Setting a glitch filter.
- Defining callbacks for getting to a specific position, overrun and
  underrun (starting the next revolution).  These callbacks can be hard
  interrupts to ensure short latency.

The encoder counts all phases of a cycle.  The span for the position is
2**32, for the revolution is 2**16.  The highest input frequency is
CPU-Clock/24.  Note that the "phases" argument is emulated at the API
level (the hardware will always count all phases).

The Counter mode counts single pulses on input A of the Encoder.  The
configuration supports:
- Defining the module.
- Defining the input pin.
- Defining the counting direction, either fixed or controlled by the level
  of an input pin.
- Defining a pin for an index signal.
- Defining an output pin showing the compare match signal.
- Setting the counter value.
- Setting the glitch filter.
- Defining a callback which is called at a certain value.
- Settings for MIMXRT1015. The MIMXRT1015 MCU has only one encoder/counter
  unit.

The counting range is 0 - 2**32-1 and a 16 bit overrun counter.  The
highest input frequency is CPU-Clock/12.

The implementation of the `.irq()` method uses the common code from
`shared/runtime/mpirq.c`, including the `irq().flags()` and
`irq().trigger()` methods.

The rp2.asm_pio() decorator saves and temporarily replaces the globals
dictionary to allow the wrapped functions to reference PIO instructions
and register names in a natural way, restoring them before returning the
assembled program.

However, if an exception occurs while assembling the program, the globals
are not changed back, leaving them corrupted.

Wrap with try/finally to ensure they are always restored correctly.

As of CPython 3.7 `bytes.fromhex()` skips all ASCII whitespace.  And as of
CPython 3.8 `bytes.hex()` supports the optional separator argument.  So
this test no longer needs a .exp file.

Angus Gratton bfc69dbe83 extmod,rp2: Keep LWIP timer running if lwip poll_sockets() is called.
Fixes rp2 issue where socket.getaddrinfo() could block indefinitely if an
interface goes down and still has a DNS server configured, as the LWIP
timer stops running and can't time out the DNS query.

Adds a regression test under multi_wlan that times out on rp2 without this
fix.

Fixes issue #18797.

Damien George 63e452920b alif/machine_pwm: Implement machine.PWM.
This commit adds `machine.PWM` support to the alif port.  It uses the
existing common machine bindings and implements the standard set of
functionality: `freq()`, `duty_u16()`, `duty_ns()` and `invert`.

It uses the UTIMER peripheral and makes PWM available on all pins that have
an alt function connection to a UTIMER, which is 54 pins.  It does not use
UTIMER11 which is already in use by the HE core for its systick timer.  So
the following pins don't have PWM available because they need UTIMER11:
P2_6, P2_7, P7_6, P7_7, P12_6, P12_7.

Damien George 1a01f76482 alif/modmachine: Implement timeout_ms argument to deepsleep.
This allows `machine.deepsleep(N)` to wake the device after the timout N
seconds.

Could probably also do the same thing for lightsleep.

Note that this uses the LPTIMER0 resource, which would not work if
`MICROPY_HW_SYSTEM_TICK_USE_LPTIMER` was ever enabled (it's currently never
enabled, so OK for now).
