8785fbc6f1 Trait for UsbSupply
Eliminated a signal by using a simpler trait method that returns whether VBus power is available. Also includes a UsbSupply that can be signalled for use with the nRF softdevice. Includes the requirement for waiting for power to become available.

c46e9b6cfc Introduces EnabledUsbDevice
EnabledUsbDevice is a wrapper around the UsbDevice where their enablement is also subject to external events, such as POWER events for nRF. It is introduced generically to support other platforms should they also require external signalling for enablement.

817: Added a pubsub channel implementation r=lulf a=diondokter

This is similar to Tokio's Broadcast channel, except that it doesn't allocate.

The publishers and subscribers are dynamic. They use an &dyn channel reference because it's really annoying to have to specify the mutex and const generics every time.
Do we need fully generic types as well?

1f746e0939 Remove the authors field from Cargo.tomls
It currently contains whoever was first to write some code for the crate,
even if many more people have contributed to it later.

The field is "sort of" deprecated, it was made optional recently:
https://rust-lang.github.io/rfcs/3052-optional-authors-field.html

Due the the reasons listed there I believe removing it is better than
setting it to generic fluff like "The Embassy contributors".

806: Add embassy-cortex-m crate. r=Dirbaio a=Dirbaio

- Move Interrupt and InterruptExecutor from `embassy` to `embassy-cortex-m`.
- Move Unborrow from `embassy` to `embassy-hal-common` (nothing in `embassy` requires it anymore)
- Move PeripheralMutex from `embassy-hal-common` to `embassy-cortex-m`.

99d19c7dcf Rename channel to mpmc
I've renamed the channel module for the MPMC as mpmc. There was a previous debate about this, but I feel that the strategy here avoids importing `channel::channel`. The change leaves `signal::Signal`, but I think that's ok. It is all a bit subjective of course. The bottom line for me is that I really like the term mpmc - it means something to me and aligns with broader naming e.g. in Tokio.

781:  embassy-net v2 r=Dirbaio a=Dirbaio

- No more `dyn`
- It's no longer a global singleton, you can create muliple net stacks at once.
  - You can't tear them down though, the Device it still has to be `'static` due to restrictions with smoltcp's "fake GAT" in the Device trait. :(
- Removed `_embassy_rand` hack, random seed is passed on creation.



785: stm32: g0: add PLL clock source r=Dirbaio a=willglynn

STM32G0 SYSCLK can be sourced from PLLRCLK. Given that the HSI runs at 16 MHz and the HSE range is 4-48 MHz, the PLL is the only way to reach 64 MHz. This commit adds `ClockSrc::PLL`.

The PLL sources from either HSI16 or HSE, divides it by `m`, and locks its VCO to multiple `n`. It then divides the VCO by `r`, `p`, and `q` to produce up to three associated clock signals:

  * PLLRCLK is one of the inputs on the SYSCLK mux. This is the main reason the user will configure the PLL, so `r` is mandatory and the output is enabled unconditionally.
  * PLLPCLK is available as a clock source for the ADC and I2S peripherals, so `p` is optional and the output is conditional.
  * PLLQCLK exists only on STM32G0B0xx, and exists only to feed the MCO and MCO2 peripherals, so `q` is optional and the output is conditional.

When the user specifies `ClockSrc::PLL(PllConfig)`, `rcc::init()` calls `PllConfig::init()` which initializes the PLL per [RM0454]. It disables the PLL, waits for it to stop, enables the source oscillator, configures the PLL, waits for it to lock, and then enables the appropriate outputs. `rcc::init()` then switches the clock source to PLLRCLK.

`rcc::init()` is now also resonsible for calculating and setting flash wait states. SYSCLCK < 24 MHz is fine in the reset state, but 24-48 MHz requires waiting 1 cycle and 48-64 MHz requires waiting 2 cycles. (This was likely a blocker for anyone using HSE >= 24 MHz, with or without the PLL.) Flash accesses are now automatically slowed down as needed before changing the clock source, and sped up as permitted after changing the clock source. The number of flash wait states also determines if flash prefetching will be profitable, so that is now handled automatically too.

[RM0454]: https://www.st.com/resource/en/reference_manual/rm0454-stm32g0x0-advanced-armbased-32bit-mcus-stmicroelectronics.pdf

The initial closure is not actually called in the interrupt, so this is
illegally sending non-Send futures to the interrupt.

c0de54a341 usb-hid: Simplify API.
- Renamed structs to HidReaderWriter, HidReader, HidWriter.
- 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.
