561: stm32/dac: Fix disable_channel r=Dirbaio a=bgamari
Previously disable_channel enabled rather than disabled the requested
channel due to an apparent copy-paste error. Refactor to eliminate this
sort of issue by construction.

551: nrf/gpio: add infallible inherent methods, remove some duplication. r=Dirbaio a=Dirbaio
Add infallible inherent methods, so that users don't have to import a trait, or `.unwrap()`.
This implements Input and Output using FlexPin, to avoid some code duplication.

This allows writing drivers relying on async traits, while still
functioning with implementations that already implement the embedded-hal
traits.
Add examples to stm32l4 for using this feature.
548: Set Uarte log levels to trace r=lulf a=huntc
I noticed lots of logging which really slows things down and is not useful outside of a debugging context, hence set to trace.

544: Introduces split on the nRF Uarte r=Dirbaio a=huntc
A new `split` method is introduced such that the Uarte tx and rx can be used from separate tasks. An MPSC is used in an example to illustrate how data may be passed between these tasks.
The approach taken within the `Uarte` struct is to split into tx and rx fields on calling `Uarte::new`. These fields are returned given a call to `Uarte::split`, but otherwise, if that call isn't made, then the API remains as it was before.
Here's a snippet from a new example introduced:
```rust
#[embassy::main]
async fn main(spawner: Spawner, p: Peripherals) {
// ...
let uart = uarte::Uarte::new(p.UARTE0, irq, p.P0_08, p.P0_06, NoPin, NoPin, config);
let (mut tx, rx) = uart.split();
// ...
// Spawn a task responsible purely for reading
unwrap!(spawner.spawn(reader(rx, s)));
// ...
// Continue reading in this main task and write
// back out the buffer we receive from the read
// task.
loop {
if let Some(buf) = r.recv().await {
info!("writing...");
unwrap!(tx.write(&buf).await);
}
}
}
#[embassy::task]
async fn reader(mut rx: UarteRx<'static, UARTE0>, s: Sender<'static, Noop, [u8; 8], 1>) {
let mut buf = [0; 8];
loop {
info!("reading...");
unwrap!(rx.read(&mut buf).await);
unwrap!(s.send(buf).await);
}
}
```

540: Initial support for STM32F3 r=Dirbaio a=VasanthakumarV
The [companion PR](https://github.com/embassy-rs/stm32-data/pull/109) in `stm32-data` should be merged before this PR.
The examples were tested on an STM32F303VC MCU.

543: Incrementally merge STM32 SPI versions, Part 3 r=Dirbaio a=GrantM11235
Notable changes:
- `SPE` is now disabled before `TXDMAEN` and `RXDMAEN` are disabled. This is the "mandatory" sequence for v2 and v3 (and maybe v1 as well, but I can't find it in the reference manual).
- v1's `write_dma_u8` now waits for idle and disables `TXDMAEN` after the transfer is complete, just like everything else.
