* Force frame pointers for RISC-V chips
* Various dependency updates
* Update to latest published PACs and resolve build errors
* Top-level `README` updates
* Further clarify when `RUSCT_BOOTSTRAP=1` is required
* Make sure examples can build with defmt
* Remove duplicate example checks
* Fix examples
* Add changelog entry
* Actually build some examples with defmt feature enabled
* Add the defmt linker script in each package's build script
* Bump MSRV to 1.67, check with `defmt` feature enabled in MSRV checks where applicable
* Add `esp32c6-lp-hal-procmacros` package to VS Code workspace
* Update `CHANGELOG.md`
* Executor related touchups
* Make log optional
* Add defmt feature and derive on Debug structs
* Test both log drivers
* Update esp-println
* Document defmt msrv
* Update a bunch of dependencies
* Implement `embedded-io` and `embedded-io-async` traits for USB Serial JTAG
* Implement `embedded-io` and `embedded-io-async` traits for UART
* Fix `embassy_serial` examples
* Update CHANGELOG
* Address review comments
* Small refactor to extract functions for setting up reads/writes
* Implement async capabilities for `I2C` driver
* Add async I2C examples for each supported chip
* Update CHANGELOG
* Initial async_{write|flush} implementations
- ESP32C3 + UART0 example
* Support UART1 & UART2
* Add examples for all chips
* reduce number of wakers depending on uart count
* Update `embedded-hal-1` and `embedded-hal-nb` dependencies to latest versions
* Update the `Delay` and `I2c` trait implementations
* Update the `SpiDevice` trait, implement `SpiDeviceRead` and `SpiDeviceWrite`
* Add additional `cfg` gates to re-exports in `esp-hal-common`
This leaves only `clock`, `delay`, `peripheral`, `prelude`, `rom`, and `soc` *not* behind `cfg`s
* Simplify the prelude, update its `cfg`s, and re-export some missing traits
* Update various dependencies
* Extract the `esp-hal-smartled` package
This (finally) eliminates the `esp_hal_common::utils` module!
* Remove all references to the old `smartled` feature from CI
* ground work for async dma (gdma only atm)
* Add async DMA (GDMA) - esp32c3/esp32c2
* Add Async SPI impl for esp32c3/c2
* Remove private modules from DMA
* add async spi example for esp32c3
* Switch to assoc wakers instead of a static array
* add support for esp32/esp32s2
* add support for esp32s3
* run fmt
* add c2 example, fix CI
* Remove redundant comments
* Add `is_listening` to `Pin` trait
* Add `Wait` impl for Gpio Input
* Add GPIO wait example for C3
* Ensure correct bank is accessed in interrupt
* Add esp32c2 wait example
* Add esp32s3 wait example
* Add esp32s2 wait example
* Add esp32 wait example
* Run fmt
* Add example to cargo tomls
* Add top level docs for embassy examples
* Mention the higher MSRV for async in the README
