DTS modules (device modules) often have a single source file with an empty `struct Module`.
The module's yaml file now allows a `dts-only` boolean to be set, so the source file becomes optional.
`devicetree.yaml` is renamed everywhere to `module.yaml`
* **New Features**
* Added native display support for ST7796, ILI9341, and ST7789 panels across supported boards.
* Added FT5x06 and FT6x36 touchscreen support.
* Generic PWM driver
* ESP32 PWM driver
* Generic RGB LED driver
* RGB PWM LED driver
* RGB GPIO LED driver
* Implementation of RGB LED for various boards
* **Improvements**
* Updated board hardware descriptions to use explicit display/touch/backlight device-tree bindings and disabled deprecated HAL usage.
* Improved display and touch-driver cleanup to prevent stale resources and improve shutdown reliability.
* Pinned esp-hosted library to a fixed version
* **Deletions**
* Obsolete placeholder display
* Legacy ILI9488 support.
* ESP32-specific LEDC PWM implementation
- 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).
