Kernel improvements (#485)
* **New Features**
  * Added public accessors for querying module/device start and ready state.

* **Refactor**
  * Internal state moved to opaque internal objects; module/device/driver initializers now explicitly initialize internal pointers.
  * Lifecycle handling updated to construct/destruct internal state and use accessors.

* **Tests**
  * Tests updated to use public accessors and explicit construct/destruct lifecycle calls.

* **Chores**
  * Test build/include paths and small metadata updated.

I2S driver implementation (#480)
* **New Features**
  * ESP32 I2S controller support: runtime-configurable digital audio I/O with read/write/set/get operations and multiple formats.

* **Board Support**
  * LilyGO T-Deck device tree entry added to enable I2S peripheral pin configuration.

* **Documentation**
  * New/updated bindings and descriptors for I2S, I2C, GPIO, and root nodes.

* **Other**
  * Added GPIO "no pin" sentinel and exposed I2S controller API symbols.

Kernel and buildscript improvements (#477)
* **New Features**
  * Centralized module management with global symbol resolution
  * Level-aware logging with colored prefixes and millisecond timestamps

* **Breaking Changes**
  * ModuleParent hierarchy and getModuleParent() removed
  * Logging API and adapter model replaced; LogLevel-driven log_generic signature changed

* **Improvements**
  * Unified, simplified module registration across build targets
  * Tests updated to reflect new module lifecycle and global symbol resolution

Refactor LVGL code into kernel module (#472)
* **New Features**
  * Added a standalone LVGL module and enabled LVGL support in the simulator for richer local UI testing.

* **Refactor**
  * HAL and LVGL split into distinct modules; startup and device attach/detach flows reorganized for clearer lifecycle management.
  * Public APIs tightened with clearer nullability/documentation.

* **Bug Fixes**
  * More consistent LVGL start/stop and device attach/detach behavior for improved stability.

Partial reimplementation of TactilityC GPIO (#469)
* **New Features**
  * Added a GPIO hardware abstraction layer for reading pin levels from applications.
  * Applications can now query the number of available GPIO pins so they can adapt to different devices.
* **Chores**
  * Integrations updated so GPIO capabilities are discoverable and exported to running applications.

Kernel improvements (#468)
* **New Features**
  * Plugin-style modules for platforms and devices with start/stop lifecycle and a runtime-consumable device tree array.

* **Refactor**
  * Consolidated initialization into a kernel/module startup flow.
  * Generated devicetree artifacts moved to the build Generated directory.

* **Changes**
  * Removed legacy no-op registration hooks and I2C lock/unlock wrappers.
  * Driver ownership and private state moved to explicit module/owner model.
  * Added ERROR_NOT_ALLOWED error code.

TactilityKernel improvements (#464)
* **New Features**
  * Thread API with lifecycle, priority, affinity and state monitoring
  * Timer subsystem: one-shot/periodic timers, reset, pending callbacks, expiry queries
  * Expanded I²C: register-level ops, bulk writes, presence checks, ESP32 integration and new config properties
  * GPIO controller: pin level and options APIs
  * Error utilities: new error code, error-to-string, timeout helper and common macros
  * Device construction helpers (construct+start)

* **Tests**
  * New unit tests for thread and timer behavior

* **Documentation**
  * Expanded coding style guide (files/folders, C conventions)

Moved and renamed files for consistent C code style (#463)
* **Documentation**
  * Added new C coding style guide detailing naming conventions for files, directories, macros, constants, variables, functions, and type definitions with illustrative examples.
  * Updated C++ coding style documentation with clarifications on C naming conventions and header directory organization patterns.

* **Refactor**
  * Updated header include paths throughout the codebase to use lowercase naming conventions consistently.

Implemented TactilityKernel and DevicetreeCompiler, updated licenses & copyrights (#452)
**New features**

- Created a devicetree DTS and YAML parser in Python
- Created new modules:
  - TactilityKernel (LGPL v3.0 license)
  - Platforms/PlatformEsp32 (LGPL v3.0 license)
