1119: add convert_to_celsius function in the adc module r=lulf a=overheat
modify RP2040 adc example to get inside biased bipolar diode voltage,
then convert this temperature sensor data into Celsius degree,
according to chapter 4.9.5. Temperature Sensor in RP2040 datasheet.

1114: nrf/uart: do not error on zero length transfers. r=Dirbaio a=Dirbaio
It's a perfectly fine thing to do, should be just a noop. Erroring is really annoying when you're writing a payload to uart that might be zero-length or not.

It's a perfectly fine thing to do, should be just a noop. Erroring is
really annoying when you're writing a payload to uart that might
be zero-length or not.
The eth code is always built and available, but has no own API (other
than the embassy-net Device impl) to rx/tx packets. We could add this
API in the future, so the feature only means "embassy-net support".
The pool was prone to deadlocks, especially due to having a single pool
for rx+tx. If the pool got full with rx'd packets it would deadlock because
processing a rx packet requires doing another allocation on the pool, for
the possibly tx'd response, before deallocating the rx'd packet.
This also allows Device impls to allocate the packet memory in a particular
RAM kind, if needed for example to do DMA.
The `Device` trait is now token-based, like smoltcp's. In the end, this
is better because it allows callers to manage memory however they want (including
with a pool if they want to).
1105: embassy-rp: Add multicore support r=Dirbaio a=kalkyl
This PR adds multicore support + critical-section impl using hardware spinlocks.
Based on the rp2040-hal implementation.

1043: Rpi Pico PIO driver r=Dirbaio a=fluffware
This is a driver for the two PIOs in the Pico. I've tried using the type system to get as much compile time checks as possible. There is asynchronous support for FIFOs an Irqs. No DMA support yet. There's an example that shows how to use the driver asynchronously.

1051: Adapted nvmc so it can be used for all nrf targets r=diondokter a=diondokter
Title says it all pretty much.
It's a bit annoying with the configs though.
I've made this a draft because I haven't really tested this yet.
