855: PDM microphone support for nrf r=Dirbaio a=pbert519
PDM microphones have a long startup phase, therefore the driver samples continuously and only switches the target buffer if the user requests sampling.

1021: rp usb: wait for accept() completion r=Dirbaio a=mkj
This fixes failures when `defmt` feature isn't enabled (timing related).

This ensures that the current response has finished being sent
before the subsequent set_address() happens. Otherwise connecting
a device is intermittent, can fail depending on timing.
1014: Add memory barriers to H7 flash driver to mitigate PGSERR errors r=lulf a=matoushybl
The stm32h7xx-hal uses only the ordering barrier, while the CubeMX uses the DSB and ISB instructions, to be on the safe side, both are used here.
Without the barrier, the PG bit is not set, when the writes are being done, resulting in an error.

1012: rp i2c: have separate wakers for each i2c unit r=Dirbaio a=jsgf
If they both share one waker, there's the possibility that some wakeups could get lost.

984: rp pico async i2c implementation r=Dirbaio a=jsgf
This implements an interrupt-driven async i2c master. It is based on https://github.com/embassy-rs/embassy/pull/914, a bit of https://github.com/embassy-rs/embassy/pull/978 and `@ithinuel's` https://github.com/ithinuel/rp2040-async-i2c.git
This is still work-in-progress, and is currently untested.
1006: Removes some of the code duplication for UarteWithIdle r=Dirbaio a=huntc
This PR removes some of the code duplications for `UarteWithIdle` at the slight expense of requiring a split when using idle processing. As the nRF example illustrates though given the LoC removed, this expense seems worth the benefit in terms of maintenance, and the avoidance of copying over methods. My main motivation for this PR was actually due to the `event_endtx` method not having been copied across to the idle-related code.
Tested the uart_idle example on my nRF52840-dk, and from within my app. Both appear to work fine.

985: Create Sx126X LORA driver r=lulf a=ceekdee
Implementation features:
- update embassy-lora to support Semtech SX126X chips, specifically the RAK4631 chip (nrf52480 and sx1262).
- support additional SX126X packages by adding a feature (reference feature rak4631) and updating the board specific Rust file. To enable feature rak4631, settings.json must currently enable "rust-analyzer.linkedProjects" for "examples/nrf/Cargo.toml".
- provide tx/rx examples in examples/nrf to show compatibility with the interface provided by the SX127X LORA implementation.
Only LORA P2P communication has been tested. Implementation lines marked with ??? indicate areas for further investigation. Furthermore, I question whether the DIO1 handler is adequate for catching all interrupt sequences.
This implementation is patterned after the C/C++ implementation provided by Semtech, available through the RAK-nRF52-RUI developers platform.

1004: Fix internal channels for adc v2 r=lulf a=chemicstry
Internal channel reading was broken on adc_v2, because `Adc::read()` requires gpio pin trait, which was not implemented by `VrefInt`, `Temperature`, `Vbat`. The required configuration bits `tsvrefe`, `vbate` were not enabled either. This PR makes it a bit closer to how adc_v4 works.
While at it, I also changed adc_v2 to use `RccPeripheral` instead of permanently enabling all ADCs.
