Different STM32 RCC peripherals have different capabilities and register
values. Define types for each RCC types inside each module to ensure
full range of capabilities for each family can be used
This fix build on F0, since it doesn't have DMARST. This change makes
RccPeripheral::reset a no-op on peripherals where a reset field couldn't
be found
* Chips that have multiple cores will be exposed as chipname_corename,
i.e. stm32wl55jc_cm4
* Chips that have single cores will use the chip family as feature name
and pick the first and only core from the list
* Add support for stm32wl55 chip family
Currently this looks up the frequency in the global singleton that must
be initialized by the per-chip RCC implementation. At present, this is
only done for the L0 family of chips.
Adds RccPeripheral trait for peripherals implementing clock enable and reset for a given peripheral.
Add macro table generting implementations of RccPeripheral for peripherals with clock set, currently restricted to SPI.
Modify init function to return a Clock instance defined by a per-chip
SystemClock type and use this in macro setup
A proof of concept implementation for STM32 L0 chips.
This allows using embassy::main macros for STM32 devices that have the
clock setup logic.
