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.

This sets the license to "MIT OR Apache-2.0" in a machine readable form on all crates, as it was already in human readable form in the README.md file, and reaffirmed in #1002.

(The statements on all the individual examples might not be strictly essential for the `cargo deny` use case as they are leaf crates, but other tools might use that information).

4fd831e4a8 rp async i2c: raise the tx_empty threshold
Assert "tx_empty" interrupt a little early so there's time to wake up
and start refilling the fifo before it drains. This avoids stalling the
i2c bus if the tx fifo completely drains.

This is an interrupt-driven async i2c master implementation. It makes as

interrupts.

It implements embedded_hal_async::i2c for easy interop.

992: (embassy-stm32): remove flash lock/unlock public API from stm32 flash r=lulf a=MathiasKoch

Instead, perform the unlocking and locking automatically on erase and write operations.

This makes the `embedded-storage` abstraction actually useable in libraries, while still keeping the flash peripheral locked the majority of the time.

990: Small pubsub improvements r=Dirbaio a=diondokter

- Futures in pub & sub are now awaited instead of returned
- Added functions for reading how many messages are available

This helps people get better compiler diagnostics. For example, I forgot to call await on a future and the compiler didn't complain.
This also helps with making some decisions based on the state of the channels.
