- Added modular device support and devicetree bindings for ILI9341, ILI9488, CST816S, XPT2046, and GPIO button input, updating several board configurations for display/touch/backlight/keyboard/battery.
- Added a setting to control deprecated HAL usage (device property + Kconfig).
* **Refactor**
* GPIO subsystem moved to a descriptor-based model for per-pin ownership and runtime pin management; many platform drivers now acquire/release descriptors.
* Device trees and drivers now use GPIO phandle-style pin specifications across all boards and all drivers.
* **Behavior**
* Device list now encodes per-device status (ok/disabled); boot will skip disabled devices accordingly.
* **Deprecation**
* Legacy GPIO HAL marked deprecated and replaced with descriptor-based interfaces.
* **Chores**
* Bindings and platform configs updated to the new GPIO pin-spec format.
* **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.
* **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.
**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
- Refactor `Ili934xDisplay` to use `EspLcdSpiDisplay` as base class
- Update `St7789Display` for changes to `EspLcdDisplayV2` related to ILI934x driver
- Updated all board driver implementations for ILI934x driver changes
- Simplified board configurations:
- All boards now have a `Configuration.cpp`
- All board config's headers are removed
- Removed `Boards.h`
- Fix for untar-ing large files
- Increase main task stack size to avoid stackoverflow when downloading apps in App Hub
- Reduce SPI frequency for ST7789 displays (according to spec)
