767: Stm32 fixes r=lulf a=jr-oss
Using embassy on STM32 Discovery board showed problems with
- USART with parity
- Clock settings (CFGR) when using PLL and prescaler
- Flash ACR settings
This PR attempts to fix these
Co-authored-by: Ralf <jr-oss@gmx.net>
PLL settings remained intact because these bits are not writable when PLL is enabled,
but prescaler settings were overwritten by selecting PLL as sysclk (CFGR.SW[1:0]).
765: Implement Output::is_set_low for embassy-rp r=Dirbaio a=danbev
This commit implements a suggestion for the method `is_set_low` which is
currently a `todo`, by reading last value written to `GPIO_OUT`.

751: Use explicit return statement TaskStorage::spawn r=Dirbaio a=danbev
This commit removes the else branch in `TaskStorage::spawn`, and returns
explicitly from the if statement's branch, similar to what
[TaskPool::spawn](85c0525e01/embassy/src/executor/raw/mod.rs (L235-L243)) does.

This commit removes the else branch in TaskStorage::spawn, and returns
explicitly from the if statement's branch, similar to what
TaskPool::spawn does.
The replacement is `embassy-usb`. There's a WIP driver for stm32 USBD in #709,
there's no WIP driver for stm32 USB_OTG. This means we're left without
USB_OTG support for now.
Reason for removing is I'm going to soon remove `embassy::io`, and
USB uses it. I don't want to spend time maintaining "dead" code
that is going to be removed. Volunteers welcome, either to update
old USB to the new IO, or write a USB_OTG driver fo the new USB.
749: Rename spawn_allocate to spawn_mark_used r=Dirbaio a=danbev
This commit contains a suggestion to rename `TaskStorage::spawn_allocate`.
The motivation for this is when reading through the code I was
expecting something else to happen in this method, due to `allocate` in
the method name.
I'm very new to this code base so I may be wrong in thinking this
is a good change, but I wanted to open this PR to get some feedback.

743: Add PLL config support for F2 r=Dirbaio a=Gekkio
- minor changes to make the F2 RCC API a bit more flexible
- low-level PLL config with assertions based on datasheet specs. It shouldn't be very difficult to later add a "reverse API" where you pass the clocks you want to a function and it generates a `PLLConfig` struct for you
- PLL API tested on my custom board with 12 MHz HSE as source for PLL to generate max clocks for SYSCLK/AHB/APB/APB1/PLL48
- the example *should* work but is untested since I don't have the Nucleo board 😞

733: Add f107 ethernet support. r=Dirbaio a=davidlenfesty
The original driver works perfectly, the only required changes were only to clock and pin configuration.
Bits that are also present and deserve some scrutiny:
- Migrated LAN8742a driver to a generic SMI version (only *functional* difference is a couple extra status checks for the link poll, which IMO weren't great anyways (i.e. it would consider the link down if it negotiated to 10M)
- Migrated f1 RCC init to "new" style. As of creating this draft PR, it is pretty much only tested on the happy path for my specific configuration, and also needs a couple things done (calculated clock speeds are hardcoded and ADC clock isn't implemented)
- Support for v1b driver (f2 and f4) was added, but not tested.
(Made a draft PR until f4 support is verified and I finish the clock init - adding testing and at least feature parity with how it was before)

SMI Ethernet PHYs all share a common base set of registers that can do
90% of all tasks. The LAN8742 driver used some vendor-specific
registers to check link negotiation status, but the need for that was
debatable, so I migrated it to a generic driver instead, anybody who
wants extra functionality can copy it and impl their own on top of it.
