48afef28a0 Strengthen the borrow
The start method is now safe. Because it has the potential of borrowing the sequence and mutating itself, the sequence must outlive the Pwm struct.

7598b8a40f Permit many sequences to be passed
Sequences are now passed in via the start method to avoid having to stop the PWM and restart it. Sequences continue to be constrained with the same lifetime of the Pwm object itself. The pwm_sequence example has been extended to illustrate multiple sequences being passed around.

d5d8897c84 Remove unsafe from new on RND
Unsafe is not required here given that all futures are required to live longer than their global peripheral instances. There are other occurrences of unsafe being used on new that should be removed. I started to do that but then went down a bit of a rabbit hole.

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);
    }
}
```

542: nrf/gpiote: remove PortInput, move impls to Input/FlexPin. r=Dirbaio a=Dirbaio

`PortInput` is just a dumb wrapper around `Input`, it has no reason whatsoever to exist. This PR moves the `wait_for_x` functionality to `Input` directly.

It also adds it to `FlexPin` for completeness and consistency with `Input`.

(The reason `PortInput` exists is a while ago `GPIOTE` was an owned singleton that you had to initialize, so `PortInput::new()` would require it to enforce it's been initialized. This doesn't apply anymore now that GPIOTE is "global")

469852c667 Removed unsafe from uarte
The constructors themselves are not strictly unsafe. Interactions with DMA can be generally unsafe if a future is dropped, but that's a separate issue. It is important that we use the `unsafe` keyword diligently as it can lead to confusion otherwise.

486: Pwm ppi events r=Dirbaio a=jacobrosenthal

More PWM yak shaving. I was going to do some safe pwm ppi events stuff but I just dont think it fits this api design.. ppi is just very low level, im not sure how safe it will be in general

* first we should probably have borrows of handlers for ppi with lifetime of the peripheral?  hal does eb4ba6ae42/nrf-hal-common/src/pwm.rs (L714-L716)
* in general having access to tasks can put the state in some configuration the api doesnt understand anymore. for `SequencePwm` ideally id hand you back either only seq_start0 or seq_start1 because youd only use one based on if your `Times` is even or odd.. but again we only know that with this api AFTER start has been called. I dont think were ready for typestates

SO I figured why not add the pwm ppi events but make them unsafe and commit this example since I started it.

Somewhat related drop IS removing the last duty cycle from the pin correctly, but stop DOES NOT..the only thing that sets the pin back is pin.conf() as far as I can tell, so I tried to document that better and got rid of stop for the `SimplePwm` again since that doesnt need it then. However its ackward we dont have a way to unset the pwm without setting a new sequence of 0s, or dropping the peripheral

482: Add MCO peripheral. r=Dirbaio a=matoushybl

This PR adds an abstraction over STM32 RCC feature called MCO (Microcontroller Clock Output). The clock output can bind to several clock sources and then can be scaled using a prescaler.

Given that from the embassy ecosystem the RCC is generaly invisible to the user, the MCO was implemented as a separate peripheral bound to the pin where the clock should appear.

Rustflags apply to ALL the crates in the graph, while we only need
them for the toplevel crate which is the only one getting linked.

Rustflags are not equal for all crates, this caused cargo to re-build the
same dependency crate multiple times uselessly. After this change, deps
are reused more, making builds faster.

Note that this only applies when sharing the target/ dir for multiple crates
in the repo which is not the default.
