900: net: make TcpIo private. r=Dirbaio a=Dirbaio
It's just an implementation detail to share code between Socket, Reader, Writer. It wasn't supposed to be public.

896: Implement I2C pullup configuration r=lulf a=chemicstry
I wasn't sure if I should put frequency into config struct, so left it separate as in SPI periph.
Also added Copy derives to gpio types, not sure why they weren't?

892: Merge v1, v2 DAC and update register definitions r=Dirbaio a=chemicstry
This merges v1 (unimplemented) and v2 DAC implementations, because they share most of the code except for some exotic stuff, which is not yet implemented for neither of the versions. This should allow using DAC on all chips that have v1 peripheral.

888: Extend QSPI config with freq, delay, spi mode, and address mode r=Dirbaio a=TilBlechschmidt
Fixes#886 among some of the TODOs which have been flying around in the source file :)
I'll make one more commit to remove some old commented out code from the file and take some time this evening to verify that it works.

887: executor: miri fixes r=Dirbaio a=Dirbaio
Fixes a few MIRI errors due to loosely mixing `&TaskStorage<F>` and `&TaskHeader`. References "downgrade" the provenance. `TaskHeader` is smaller, so once you have a `&TaskHeader` you can't use pointer casts to access the whole `TaskStorage<F>`. This fixes it by always keeping the raw pointer around, which doesn't downgrade provenance.
The error was:
```

879: Improve ADC configuration options r=Dirbaio a=chemicstry
This smooths out a few rough edges with ADC:
- Make `Resolution::to_max_count()` pub for all ADC versions. Useful if performing conversion manually.
- `VREF` and `VREFINT` were convoluted. `VREF` is an external voltage reference used for all ADC conversions and it is exposed as a separate pin on large chips, while on smaller ones it is connected to `VDDA` internally. `VREFINT` is an internal voltage reference connected to one of the ADC channels and can be used to calculate unknown `VREF` voltage.
- Add a separate `VREF_DEFAULT_MV`, equal to 3.3V, which is the usual supply voltage and should work for most simple cases.
- For an external voltage reference `set_vref()` can be used to set a known precise voltage.
- If no voltage reference is present, `VREFINT` calibration can be used to calculate unknown `VREF` voltage. If I understand correctly, this is only implemented for `adc_v3` (L4?), but is not currently exposed (private). If someone is interested, this can be fixed in separate PR.

876: Add defmt support to embassy-embedded-hal errors r=Dirbaio a=matoushybl
`defmt::unwrap!()` should now work with shared buses. I tested it only with I2C as I don't have SPI in the target project.

856: embassy-stm32/pwm: Generalize channel selection r=Dirbaio a=bgamari
550da471be previously refactored the STM32
PWM logic in such a way to preclude use of non-contiguous channels (e.g.
channel 2 but not channel 1). Refactor it yet again to yet again allow
this sort of usage.
