* **DevicetreeCompiler**
* Binding properties now support default values.
* Compiler returns meaningful exit codes and reports errors more clearly.
* Stronger validation of device configurations with unified error handling.
* Added integration tests and a dedicated Devicetree test workflow.
* **Changes**
* Platform binding schemas updated: some fields made required, others gained explicit defaults.
* Many device-tree files simplified by removing unused/placeholder pin and transfer-size entries.
* **Documentation**
* Removed several outdated TODO items.
- Implement SPI devices in dts files for all devices
- Removed `tt::hal::spi` HAL and its configurations
- Fix for devicetree generator "boolean" support
- Remove unused custom locks in all `DisplayDevice` implementations
- Fixed some bugs with devices
- Updated XPT2046 driver
- Fix for `WifiEsp` deadlock
- Export a lot of new `math.h` symbols with `tt_init.cpp`
- Created `SpiDeviceLock` in `TactilityCore` as a wrapper for kernel SPI locking
- Improved `TactilityKernel` SPI driver.
Devictree changes:
- Create DTS files for all remaining devices
- Update corresponding `devicetree.yaml`
- Remove `i2c` configuration from corresponding `tt::hal::Configuration`
Apps & HAL:
- Removed I2C Settings (we'll make a new one later after I rework that part of the HAL)
- Delete TactilityC GPIO and I2C functionality
- Delete Related SystemEvent types
- Refactor `tt::hal::i2c` to only use `struct Device*` wrapping
Scripting:
- Fix DevicetreeCompiler boolean parsing
- Create `build-all.py`
