rp: add missing `Debug` and `defmt::Format` `derive`s for ADC

2025-05-15T16:38:04+00:00

this doesn't cover every `struct` & co. in `embassy-rp`, but at least it
adds those needed for `Adc` and `adc::Channel`.

Remove Peripheral trait, rename PeripheralRef->Peri.

Fix PeripheralRef soundness issue allowing &T.

2024-05-07T21:26:15+00:00

Fix soundness issue introduced in a previous soundness fix https://github.com/embassy-rs/embassy/pull/2602 .
PeripheralRef must not implement DerefMut itself, but the blanket impl must still require DerefMut. Otherwise
you can create two instances of a driver on the same uart by using `&my_uart`.

hal-internal: remove impl DerefMut for PeripheralRef.

2024-02-20T00:02:15+00:00

if you have `PeripheralRef<'a, AnyPIn>` for pin A, and `AnyPin` (owned) for pin B, you can `mem::swap` them.
so, getting access forever to pin A, just by "sacrificing" pin B

this defeats the point of PeripheralRef, which is if you got a `PeripheralRef<'a, T>` then you're only allowed to use the peripheral for `'a`.

Also some drivers rely on the fact only one instance of a singleton exists for soundness, so this is a soundness fix for those.

docs: document all public apis of embedded-hal-internal

2023-12-08T21:37:39+00:00

* Make some fields and functions non-public where possible.
* Enable doc warnings for missing public API docs.

Rename embassy-hal-common to embassy-hal-internal, document it's for internal use only. (#1700)
