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.

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.

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 commit removes some of the code duplication for UarteWithIdle at the expense of requiring a split.

My main motivation for this commit was actually due to the `event_endtx` method not having been copied across.
Simple example exercising an mcp23017 GPIO expander, configured on
RP2040 GPIOs 14+15 (i2c1) with 8 inputs and 8 outputs. Input bit 0
controls whether to display a mcp23017 register dump.
This is an interrupt-driven async i2c master implementation. It makes as
best use of the RP2040's i2c block's fifos as possible to minimize
interrupts.
It implements embedded_hal_async::i2c for easy interop.
WIP async impl
Compiler will infer a different lifetime for BootFlash than for the
borrowed flash, which makes it require more type annotations than if it
was just owning the type. Since it doesn't really matter if it owns or
borrows in practical use, change it to own so that it simplifies usage.
839: Misc LoRaWAN improvements r=lulf a=timokroeger
Trying too get `embassy-lora` running on a [LoRa-E5 Dev Board](https://wiki.seeedstudio.com/LoRa_E5_Dev_Board/).
I can see the join message arriving in the The Things Network console but the device does not receive the accept message yet.
Opening this PR anyway because I think there are some nice things to decouple the lora crate from the nucleo board.
`@lulf` Could you test if this PR breaks your LoRa setup? Marking as draft for the time being.

935: Remove generic const expressions from embassy-boot r=lulf a=lulf
* Remove the need for generic const expressions and use buffers provided in the flash config.
* Extend embedded-storage traits to simplify generics.
* Document all public APIs
* Add toplevel README
* Expose AlignedBuffer type for convenience.
* Update examples

* Update examples
Call `config()` only once at construction not with every RX and TX operation.
The Lora-E5 only supports HP mode, use that instead.
The nucleo board supports both HP and LP and should continue to work.
