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

67baec472d nrf: dump the pwm_sequence example for clarity
It is basically impossible to directly convert that example to a sequence for various reasons. You cant have multiple channels on same buffer with one sequence instance for starters, also at that clock rate and max_duty 1 period is far longer than the 3ms it was using, which would require using a new max_duty and thus require regenerating the sine table which makes it not representitive of the original example anymore

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.

2221e1fa93 Replace rustflags with build.rs extra-link-args.
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.

I haven't implemented `embassy_traits::Flash` because I want to change it to match embedded_storage, which is much better designed. 

Either way, NVMC can't do async anyway, so the best we could do is implementing the async trait in a blocking way...

425: Implements continuous sampling for the nRF SAADC r=huntc a=huntc

Implements continuous sampling for the nRF SAADC and also renames `OneShot` to `Saadc`. The one-shot behaviour is retained with the `sample` method and a new `run_sampler` method is provided for efficiently (i.e. zero copying) sampler processing. A double buffer is used for continuously sampling, which is swapped appropriately.

A sample frequency is provided and will set the internal timer of the SAADC when there is just one channel being sampled. Otherwise, PPI will be used to hook up the TIMER peripheral to drive the sampling task. Two methods are provided for this: `run_task_sampler` and `run_task_sampler` with the latter available where the compiler sees that just one channel is configured. Note that we set up the PPI and timer behaviour outside of the `Saadc` for maximum flexibility.

A callback is provided to the `run_sampler` method. This is a synchronous callback that should return in a reasonably short space of time. The SAADC could stall if it does not. A reasonable practice is to perform a small amount of processing within the callback to yield a signal, perhaps via `mpsc`. In the case of `mpsc`, the `try_send` method becomes useful.

A new example has been provided to illustrate continuous sampling, along with multiple channels and external timing:

```rust
#[embassy::main]
async fn main(_spawner: Spawner, mut p: Peripherals) {
    let config = Config::default();
    let channel_1_config = ChannelConfig::single_ended(&mut p.P0_02);
    let channel_2_config = ChannelConfig::single_ended(&mut p.P0_03);
    let channel_3_config = ChannelConfig::single_ended(&mut p.P0_04);
    let mut saadc = Saadc::new(
        p.SAADC,
        interrupt::take!(SAADC),
        config,
        [channel_1_config, channel_2_config, channel_3_config],
    );

    let mut timer = Timer::new(p.TIMER0);
    timer.set_frequency(Frequency::F1MHz);
    timer.cc(0).write(100); // We want to sample at 10KHz
    timer.cc(0).short_compare_clear();

    let mut ppi = Ppi::new(p.PPI_CH0);
    ppi.set_event(timer.cc(0).event_compare());
    ppi.set_task(saadc.task_sample());
    ppi.enable();

    timer.start();

    let mut bufs = [[[0; 3]; 50]; 2];

    let mut c = 0;
    let mut a: i32 = 0;

    saadc
        .run_task_sampler(&mut bufs, move |buf| {
            for b in buf {
                a += b[0] as i32;
            }
            c += buf.len();
            if c > 10000 {
                a = a / c as i32;
                info!("channel 1: {=i32}", a);
                c = 0;
                a = 0;
            }
            SamplerState::Sampled
        })
        .await;
}
