* wip: timg embassy driver
- read_raw on timg renamed to now()
- timg initialized and stored in static for use in the embassy driver
- timg sets alarm value
- untested whether alarms actually trigger
* TIMG timer driver for esp32, esp32s3
- Adds the timg timer block as a time driver for embassy
- Not enabled on the C3 as it only has one timer block, better to use
systimer
- s2 example added but can't build due to atomic requirements in
futures-core
* Add S2 atomic support with emulation, fixup embassy support for the S2
* Move executor & static-cell to dev deps. Make eha optional
* Add c2 support, run fmt
* Update to crates.io embassy releases
* Update eha
* update timg time driver to new trait
* Remove exception feature of esp-backtrace and use the user handler for backtracing
* Add async testing workflow
* Update systick example
* Fix S2 examples
* Update xtensa-toolchain
* set rustflags for s2 target
* Disable systick for esp32s2 until we can fix the noted issues
* review improvements
- Fix intr prio array being off by one
- emabssy time prio interrupt set to max prio
- use cfg instead of feature for systick detection
* Update example time delays
Previously it assumed that the entry point was allocated at the
beginning of the ".rwtext" output section, which is not always true.

* WIP: common/spi: Implement `SpiDevice`
to get shared access to an SPI bus directly via the HAL.
* WIP: common/spi: add SpiBusDevice::new
to create instances via a function call.
* esp32/examples: Add example for spi device trait
* common/spi: Finish "SpiDevice" implementation
for esp32. Abandons the approach of having the user pass in some generic
mutex in favor of creating the Mutex as part of the API so it isn't
exposed to the user in the first place.
* common/spi: Add more thorough docs
* esp32/examples: Fix example for eh1 "SpiDevice"
* common/spi: Implement `SpiDevice` for xtensa arch
and move the code into a submodule that is fenced with conditional
compilation directives.
* esp32/examples: Update spi device example
to the changed APIs for the timers and clocks, and add more transmission
tests to the example code.
* common/spi: Create devices from buscontroller
directly, instead of offering only the `new` method.
* common/spi: Finish `SpiBusDevice` trait
from embedded-hal 1.0.0-alpha.8.
* esp32: Update `SpiBusDevice` usage example.
* common/spi: Fix mutex types for xtensa32 esp
because the esp32/esp32s3 can use `SpinLockMutex`, whereas the esp32s2
has access only to `CriticalSectionMutex`.
* common/spi: Implement `SpiBusDevice` for riscv
based esp32c3.
* general: Add examples for spi device loopback
to all esp variants.
* common: Use esp_backtrace in spi_eh1_device examples
* common/spi: Update module documentation.
* common/spi: Use `critical_section::Mutex`
to unify locking across all esp variants.
* esp32c3-hal: Fix spi device example
* esp32c3/examples: Fix typo in used spi pins
