Tab5 power expander driver and devicetree parsing improvements (#507)
* **New Features**
  * PI4IOE5V6408 I2C I/O expander driver with public GPIO APIs
  * CLI tool to list devicetree dependencies

* **Device Tree Updates**
  * M5Stack Tab5 configured with two I2C IO expanders; PI4IOE5V6408 binding added

* **Build / Tooling**
  * Devicetree code generation integrated into build; generated artifacts and dynamic dependency resolution exposed

* **Refactor**
  * Kernel/run APIs updated to accept a null‑terminated devicetree modules array; many module symbols renamed

* **Documentation**
  * Added README and Apache‑2.0 license for new driver module

SPI device migration (#490)
- 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.

Add kernel drivers for SPI and UART and make locking APIs more consistent (#489)
- Add kernel support for SPI driver
- Add kernel support for UART driver
- Implemented ESP32 UART kernel driver
- Update existing UART-related code in Tactility to use new kernel driver
- Remove UART from tt::hal::Configuration
- Remove tt_hal_uart functionality but keep functions for now
- Update devicetrees for UART changes
- Kernel mutex and recursive mutex: improved locking API design
- Other kernel improvements
- Added device_exists_of_type() and device_find_by_name()

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.

Implement support for module symbols (#475)
* **New Features**
  - Adds module symbol support and per-module symbol tables, including LVGL symbol exports moved into a dedicated table.
* **API**
  - Adds symbol-resolution APIs and an accessor to enable dynamic lookup between modules.
* **Bug Fixes / Chores**
  - Explicitly initializes module symbol pointers across device and platform modules to avoid uninitialized state.
* **Tests**
  - Updates tests to account for symbol pointer initialization.

Create hal-device module, fix GPIO, fix tests, fix TactilityC (#471)
* **New Features**
  * Added a HAL device module providing device enumeration, type queries and a HAL↔kernel bridge.

* **Improvements**
  * Integrated HAL module into startup; standardized module names, includes and lifecycle logging; safer file append behavior; broader build support.

* **API Changes**
  * Driver lifecycle now uses explicit add/remove semantics; C and HAL device type/lookup APIs clarified.

* **Chores**
  * Added module README and Apache‑2.0 license; updated build configuration to include the new module.

* **Fixes**
  * Updated tests and object file handling to behave correctly.

Rename device modules (#470)
Standardised device module identifiers across all supported devices to use consistent naming conventions with lowercase alphanumeric and hyphen-separated formats.

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.

Create DTS files for all devices and implement I2C changes (#466)
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`

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) 
  - Platforms/PlatformPosix (LGPL v3.0 license)
  - Tests/TactilityKernelTests

Most boards have a placeholder DTS file, while T-Lora Pager has a few devices attached.

**Licenses**

Clarified licenses and copyrights better.

- Add explanation about the intent behind them.
- Added explanation about licenses for past and future subprojects
- Added more details explanations with regards to the logo usage
- Copied licenses to subprojects to make it more explicit
