* Fix code formatting
* Use CountDown instead of Delay
* Add the Pimoroni Plasma 2040 board
This PR adds the board support package and a simple example.
The example just blinks the on-board RGB LED.
An example should be added for using the board to control an LED strip.
This should probably use smart-leds with the associated PIO driver.
An example or functionality should be added for the current sensor.
* Rename LED data line from dat to data to match schematic
* Add an example for driving WS2812 LEDs
This is pretty much a copy-paste of the awesome pico_ws2812_led example.
* Remove reference in README to rp-pico
* Remove reference to pico board clock speed
I have removed this in the Plasma 2040 repository and where I copied it from, tiny2040_blinky.
* Remove redundant namespace
* Add self-reference in README to the current board's GitHub README
Fix the erroneous link in the pimoroni-tiny2040 README from which I copied.
* Update BSP authors to include 'rp-rs developers'
* Update BSP readme's to reflect current release version
* Update BSP changelogs
* Fix version number in HAL README
* Update changelog for 0.4.0 release
* Enable rt feature for irq example in Cargo.toml
* Bump pio/pio-proc deps to 0.2.0, update pio examples
* Update BSPs to latest ws2812-pio, remove unused pio dep
* Fix usage of pio_proc in doc comment
* Clean up pio doc-example
* Update rp-pico to latest i2c-pio

Make all ROM functions (normal and floating point) provide both a direct
call that does the operation and a module with a ptr() function to get
the function pointer.
* Update to PIO 0.1.0
* Update to latest ws2812-pio and i2c-pio.
These depend on pio 0.1.0, avoiding a conflict
* Rename CI tests.
Also check we can cargo build. And remove 'on host tests' that didn't
do anything.

* Add boot2 feature. Add boot2 linkage into each BSP optional on feature
* Enable boot2 feature in BSPs by default. Remove boot2 decl from all BSP examples
* Add EXTERN in memory.x for BOOT2_FIRMWARE, rename bootloader static slice to BOOT2_FIRMWARE
* Update new examples and itsy_bitsy BSP to use boot2 feature
* Remove boot2 as a dev-dependency for the BSPs, no longer needed
* Add no_mangle BOOT2_FIRMWARE to adafruit_macropad
* Fix itsy-bitsy blinky - it wasn't using the BSP, so it didn't get BOOT2_FIRMWARE linked in
If GPIO23 is low, the power supply is in low-power mode. But it
generates some noise. If GPIO23 is high, the power supply is less
efficient, but it generates less noise too.
* Implement peripheral support for i2c and an advanced example for the pico board.
* Simplify i2c peripheral bootstrap and add a "free" function to allow switching modes.
* Set dependency to futures & nostd_async to specific version/revision.
* move enum & struct to the start of the file
* Add a bit of documentation to the pico_i2c_controller_peripheral demo.
* Migrate to pico_i2c_controller_peripheral to embassy & simplify the peripheral support
nostd_async is broken since last stable roll out.
The pico_i2c_controller_peripheral is being migrated to use embassy's executor.
The Controller Async API is now aligned with embassy's traits to facilitate integration.
The peripheral no longer require async to run and now appears as an event iterator.
Embassy's support relies on unstable features (generic_associated_types and type_alias_impl_traits)
and is therefore gated behind the `embassy-traits` feature flag.
* make futures & embassy optional for the pico board too
* Pin embassy to a specific rev.
* Impl embassy_traits::i2c::WriteIter & enable unlimited transfer size on i2c
* Applies comment suggestion from @9names for the advanced i2c example.

* use `I2C block` instead of `IP`.
* Fix formatting (unnecessary space at end of line)
* Enhance explanation for why `rd_req()` is not cleared in `Iterator::next`'s
implementation.

* Created an itsy bitsy rp2040 board support package adapted from the bsp of the qt py rp2040. Special thanks to ithinuel for help in matrix
* Changed the board description so it doesn't match the qt py rp2040
* Changed blinky.rs to itsy_bitsy_blinky.rs and ran changes through cargo fmt
* Add pico_i2c_pio example
* Update pico_i2c_pio's main function documentation
* Update bootloader reference.
* Implement uart output for the pico_i2c_pio example.
* pin to a specific rev of i2c-pio
* Bump i2c-pio to get the fix for write_read
Answers on a postcard please on how to avoid `static mut` when you have
lazy initialization, and static objects holding references to other
static objects.
