716: Implement giant (chunked) DMA transfers r=Dirbaio a=matoushybl
There is a breaking change in the Channel trait in the method `remaining_transfers()`, this method however hasn't been used anywhere in the codebase and the return type changed from u16 to u32, so all of the previous use cases should work.

717: WIP: USB CDC NCM (Ethernet over USB) r=Dirbaio a=Dirbaio
TODO:
- [x] Add support for string handling in `embassy-usb`, remove the MAC addr string hax
- [x] Harden parsing of incoming NTBs to avoid panics.
- [ ] Parse all datagrams in a NDP, not just the first. -- tricky, I've made it tell the host we support only one packet per NTB instead.
- [ ] Add support for all required control transfers. -- WONTFIX, seems no OS cares about those.
- [x] Works on Linux
- [x] Doesn't work on Android, make it work
- [x] Check if it works in Windows (Win10 has some sort of CDC NCM support afaict?) -- works on Win11, CDC-NCM not supported on Win10
- [x] Check if it works in MacOS (I don't know if it's supposed to) - WORKS
I won't add the `embassy-net` driver to `embassy-usb-ncm` for now because `embassy-net` buffer management will likely be refactored soon, so there's not much point to it.

Fixes a new opaque type error in the task macro.
Full error is "opaque type's hidden type cannot be another opaque type from the same scope".
This got disallwed by the lazy-TAIT PR: https://github.com/rust-lang/rust/pull/94081
Sadly there's now some weird type inference errors with pre-lazy-TAIT
nightlies, so support for those is dropped.
The stack reads its own descriptors to figure out which endpoints
are used in which alt settings, and enables/disables them as needed.
The ControlHandler has a callback so it can get notified of alternate
setting changes, which is purely informative (it doesn't have to do anything).
727: Switch to crates.io embedded-hal, embedded-hal-async. r=Dirbaio a=Dirbaio
This temporarily removes support for the async UART trait, since it's
not yet in embedded-hal-async.

for QSPI
* Add blocking implementations of QSPI
* Use blocking implementation in new() and embedded-storage impls
* Use async implementation in embedded-storage-async impls
* Add FLASH_SIZE const generic parameter
* Own IRQ in Qspi instance to disable it on drop.

720: USB: New builder API r=Dirbaio a=Dirbaio
usb: improved descriptor building API
The same API call allocates interfaces/endpoints/etc and writes their descriptors.
This means less API calls, and less possibility to screw things up.
DescriptorWriter is now private.

The same API call allocates interfaces/endpoints/etc and writes their descriptors.
This means less API calls, and less possibility to screw things up.
DescriptorWriter is now private.
- 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.
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!

714: add more clock options for l4 and l5 r=Dirbaio a=ant32
- added an assert so it panics if pll48div is not 48Mhz
- added MSI as a clock source for PLL
- removed hsi48 option for MCUs mentioned in l4 rcc presentation
- copied some code from l4 to l5, but don't have a way of testing it.

694: Add select, select3, select4. r=Dirbaio a=Dirbaio
The difference with those from the `futures` crate is they don't return the other partially-run futures, so they can work with `!Unpin` futures which makes them much easier to use.

Small fix. Otherwise it panics when trying to use channel 1 if channel 2 does not exist.
