- don't require an irq binding for blocking-only adc
- abstract adc pins into an AnyPin like interface, erasing the actual
peripheral type at runtime.
- add pull-up/pull-down functions for adc pins
- add a test (mostly a copy of the example, to be honest)
- configure adc pads according to datasheet
- report conversion errors (although they seem exceedingly rare?)
- drop embedded-hal interfaces. embedded-hal channels can do neither
AnyPin nor pullup/pulldown without encoding both into the type
CI was not building the a.rs application due to the requirement of b.bin
having been built first. Add a feature flag to examples so that CI can
build them including a dummy application.
Update a.rs application examples so that they compile again.
- Move typelevel interrupts to a special-purpose mod: `embassy_xx::interrupt::typelevel`.
- Reexport the PAC interrupt enum in `embassy_xx::interrupt`.
This has a few advantages:
- The `embassy_xx::interrupt` module is now more "standard".
- It works with `cortex-m` functions for manipulating interrupts, for example.
- It works with RTIC.
- the interrupt enum allows holding value that can be "any interrupt at runtime", this can't be done with typelevel irqs.
- When "const-generics on enums" is stable, we can remove the typelevel interrupts without disruptive changes to `embassy_xx::interrupt`.
1471: embassy-net: Make TcpSocket::abort() async r=Dirbaio a=mkj
This lets callers ensure that the reset packet is sent to the remote host. Otherwise there isn't a way to wait for the smoltcp stack to send the reset.
Requires changes to smoltcp to wake after the reset has been sent, see https://github.com/smoltcp-rs/smoltcp/compare/master...mkj:smoltcp:abort-wake
This commit also adds a "TCP accept" demo of the problem. Without the `.await` for abort() it gets dropped before the RST packet is emitted.

This is only for f4, but it puts us equal to or ahead of the standard rust hal.

1457: TL Mbox read and write for stm32wb r=xoviat a=OueslatiGhaith
Hello,
This pull request is related to #1397 and #1401, inspired by #24, built upon the work done in #1405 and #1424, and was tested on an stm32wb55rg.
This pull request aims to add read and write functionality to the TL mailbox for stm32wb microcontrollers

exposing pac items kind of undermines the unstable-pac feature. directly
exposing register structure is also pretty inconvenient since the clock
switching code takes care of the src/aux difference in behavior, so a
user needn't really be forced to write down decomposed register values.
1458: rp: remove take!, add bind_interrupts! r=Dirbaio a=pennae
both of the uart interrupts now check a flag that only the dma rx path ever sets (and now unsets again on drop) to return early if it's not as they expect. this is ... not our preferred solution, but if bind_interrupts *must* allow mutiple handlers to be specified then this is the only way we can think of that doesn't break uarts.

It was intended to allow changing baudrate on shared spi/i2c. There's no
advantage in using it for PWM or PIO, and makes it less usable because you have to
have `embassy-embedded-hal` as a dep to use it.

execution wraps around after the end of instruction memory and wrapping
works with this, so we may as well allow program loading across this
boundary. could be useful for reusing chunks of instruction memory.
the many individual sets aren't very efficient, and almost no checks
were done to ensure that the configuration written to the hardware was
actually valid. this adresses both of these.
programs contain information we could pull from them directly and use to
validate other configuration of the state machine instead of asking the
user to pull them out and hand them to us bit by bit. unfortunately
programs do not specify how many in or out bits they use, so we can only
handle side-set and wrapping jumps like this. it's still something though.
it's only any good for PioPin because there it follows a pattern of gpio
pin alternate functions being named like that, everything else can just
as well be referred to as `pio::Thing`
1429: rp pio, √9 r=Dirbaio a=pennae
another mix of refactoring and soundness issues. most notably pio pins are now checked for being actually accessible to the pio blocks, are constructible from not just the owned peripherals but refs as well, and have their registrations to the pio block reverted once all state machines and the common block has been dropped.
state machines are now also stopped when dropped, and concurrent rx+tx using dma can finally be done in a sound manner. previously it was possible to do, but allowed users to start two concurrent transfers to the same fifo using different dma channels, which obviously would not have the expected results on average.

this *finally* allows sound implementions of bidirectional transfers
without blocking. the futures previously allowed only a single direction
to be active at any given time, and the dma transfers didn't take a
mutable reference and were thus unsound.
we can only have one active waiter for any given irq at any given time.
allowing waits for irqs on state machines bypasses this limitation and
causes lost events for all but the latest waiter for a given irq.
splitting this out also allows us to signal from state machines to other
parts of the application without monopolizing state machine access for
the irq wait, as would be necessary to make irq waiting sound.
