fc32b3750c Remove embassy_hal_common::usb.
The replacement is `embassy-usb`. There's a WIP driver for stm32 USBD in #709,
there's no WIP driver for stm32 USB_OTG. This means we're left without
USB_OTG support for now.

Reason for removing is I'm going to soon remove `embassy::io`, and
USB uses it. I don't want to spend time maintaining "dead" code
that is going to be removed. Volunteers welcome, either to update
old USB to the new IO, or write a USB_OTG driver fo the new USB.

743: Add PLL config support for F2 r=Dirbaio a=Gekkio

- minor changes to make the F2 RCC API a bit more flexible
- low-level PLL config with assertions based on datasheet specs. It shouldn't be very difficult to later add a "reverse API" where you pass the clocks you want to a function and it generates a `PLLConfig` struct for you
- PLL API tested on my custom board with 12 MHz HSE as source for PLL to generate max clocks for SYSCLK/AHB/APB/APB1/PLL48
- the example *should* work but is untested since I don't have the Nucleo board 😞

2e7b42fc5b embassy-stm32/eth: convert LAN8742 driver to generic SMI driver
SMI Ethernet PHYs all share a common base set of registers that can do
90% of all tasks. The LAN8742 driver used some vendor-specific
registers to check link negotiation status, but the need for that was
debatable, so I migrated it to a generic driver instead, anybody who
wants extra functionality can copy it and impl their own on top of it.

- Removed unused const generics on `State`.
- Simplified generics on `HidReaderWriter`.
  The class type previously was `HidClass<D, Driver<'d, USBD>, ReportReader<'d, Driver<'d, USBD>, OUT_N>, IN_N>`
  It's now `HidClass<D, Driver<'d, USBD>, IN_N, OUT_N>`. Note that the driver type `Driver<'d, USBD>` is no longer repeated.
- Constructors are now: `HidWriter::new()` for IN-only, `HidReaderWriter::new()` for IN+OUT. No complicated bounds.
- HidReaderWriter has all the methods from HidReader, HidWriter.

711: Add DeviceStateHandler, DeviceCommand channel, and remote wakeup support r=Dirbaio a=alexmoon

Apologies for the size of this PR. Once I started getting into the Vbus power management side of my device I found a couple of areas of functionality missing from embassy-usb. Specifically, I need the application to be able to respond to changes in the USB device state in order to properly control the amount of power I'm drawing from Vbus. I also wanted to enable remote wakeup support for my device.

In order to enable device state monitoring, I've created a `DeviceStateHandler` trait and made it possible to pass in an optional reference a handler implementing that trait when creating the `UsbDeviceBuilder`.

Remote wakeup required a way to send commands to the bus which is exclusively owned by the `UsbDevice::run` method. This is the same problem we were discussing for enabling/disabling the device on Vbus power events. My solution is to allow an optional `Channel` to be provided to the `UsbDeviceBuilder` (via `UsbDeviceBuilder::new_with_channel`), allowing the application to send commands into the `run` method. Right now it supports enable, disable and remote wakeup commands.

Since there's now a way to dynamically enable and disable the device, I also added `Config::start_enabled` to control whether or not the `UsbDevice` should start in the enabled state. That also allowed me to make `UsbDeviceBuilder::build` sync again and move enabling the bus into `UsbDevice::run`.

This led to a few driver changes:
1. `Driver::enable` became `Driver::into_bus`
2. `Bus::enable`, `Bus::disable`, and `Bus::remote_wakeup` were added
3. I removed `Bus::reset`, `Bus::suspend`, and `Bus::resume` because they were only ever called based on the result of `Bus::poll`. It made more sense to me to have `Bus::poll` handle the driver-specific state management itself.

I've updated the `usb_hid_keyboard` example to take advantage of all these additional features.

Let me know what you think.

Thanks!

648: Fix nRF Saadc continuous sampling r=Dirbaio a=huntc

Starting the sampling task prior to starting the SAADC peripheral can lead to unexpected buffer behaviour with multiple channels. We now provide an init callback at the point where the SAADC has started for the first time. This callback can be used to kick off sampling via PPI.

We also need to trigger the SAADC to start sampling the next buffer when the previous one is ended so that we do not drop samples - the major benefit of double buffering.

Given these additional tasks, we now simplify the API by passing in the TIMER and two PPI channels.

As a bonus, we provide an async `calibrate` method as it is recommended to use before starting up the sampling.

The example has been updated to illustrate these new features along with the simplified API.

The changes here have been tested on my nRF52840-DK.

656: stm32: Refactor DMA interrupts r=Dirbaio a=GrantM11235

Previously, every dma interrupt handler called the same `on_irq`
function which had to check the state of every dma channel.

Now, each dma interrupt handler only calls an `on_irq` method for its
corresponding channel or channels.

613: Rust stable support r=Dirbaio a=Dirbaio

This PR adds (limited) stable Rust support!

The drawbacks are: 

- No `#[embassy::task]`, `#[embassy::main]`. (requires `type_alias_impl_trait`). You have to manually allocate the tasks somewhere they'll live forever. See [example](https://github.com/embassy-rs/embassy/blob/master/examples/nrf/src/bin/raw_spawn.rs)
- No async trait impls (requires GATs). Note that the full API surface of HALs is still available through inherent methods: #552 #581 
- Some stuff is not constructible in const (requires `const_fn_trait_bound`), although there's an (ugly) workaround for the generic `Mutex`.

So it's not that bad in the end, it's fully usable for shipping production-ready firmwares. We'll still recommend nightly as the default, until GATs and `type_alias_impl_trait` are stable.

607: stm32: Add standard crate-wide macros for pin/dma traits r=Dirbaio a=Dirbaio

All drivers will declare the traits using these macros.

This has a few implications:
- ALL drivers will have an Instance trait, even for drivers that usually have only one instance (for example crc, eth)
- It's no longer possible to have a fn configure() in pin traits, drivers will have to do that some other way

In the future, build.rs will generate all the impls instead of macrotables.

Pin/Dma traits are no longer explicitly sealed, since gpio::Pin and dma::Channel are already sealed, which has the same effect. This means the `af_num()` and `request()` funcs are now public, but IMO that's okay, they're unlikely to change.

550da471be stm32: Remove OptionalPin
The idea behind OptionalPin has a few problems:

- you need to impl the signal traits for NoPin which is a bit weird https://github.com/embassy-rs/embassy/blob/master/embassy-stm32/src/dcmi.rs#L413-L416
- you can pass any combination of set/unset pins, which needs checking at runtime  https://github.com/embassy-rs/embassy/blob/master/embassy-stm32/src/dcmi.rs#L130

The replacement is to do multiple `new` constructors for each combination of pins you want to take.

591: PWM WS2812B example and flexible sequence config r=Dirbaio a=huntc

I've permitted the PWM sequences to be mutated on stopping the PWM by associating them with a new  `SingleSequencer` structure. This is so that we can perform effects on the LEDs (and other use-cases, I'm sure!). The example has been updated to illustrate the use of this by flashing a WS2812B LED.

There's also a `Sequencer` structure for more sophisticated PWM interactions, along with a `pwm_double_sequence`  example to illustrate.

These changes should make it possible to attain all of the nRF PWM functionality available.

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);
    }
}
```

`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

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.

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.

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;
}
```

cef6158c31 Extend SAADC one shot support
One-shot mode now permits the sampling of differential pins, and the sampling of multiple pins simultaneously.

A new ChannelConfig structure has been introduced so that multiple channels can be configured individually. Further, the `sample` method now accepts a buffer into which samples are written.

Along the way, I've reset some default configuration to align with Nordic's settings in their nrfx saadc driver. Specifically, the channel gain defaults to 6 (from 4) and the time defaults to 10us (from 20us).

work with embassy timers. The code is imported from Drogue Device (
https://github.com/drogue-iot/drogue-device)

The radio drivers integrate with the async LoRaWAN MAC layer in the
lorawan-device crate.

Also added is an example for the STM32WL55 and for STM32L0 (requires
the LoRa Discovery board) for LoRaWAN. Future work is to make the
underlying radio drivers using fully async SPI when communicating
with the peripheral.
