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`
- CL-32 features added:
- Hardware revision detection
- v0.3 and v0.4 keyboard
- v0.4 power supply
- Inlined epd library (was a module) and made changes to the device definition (don't do full update after 5 small updates)
- Statusbar: add support for inverted colors
- e-paper driver improvements and warning fixes
- Implemented gpio_controller_get_level()
- Keyboard support improvements (unicode for tca drivers)
Migrated devices to kernel drivers:
- guition-jc3248w535c
- m5stack-core2
- m5stack-cores3
- m5stack-papers3
New drivers:
- axp192-module
- axp2101-module
Fixes:
- Fix SD card LDO for P4 devices
- Updated PowerOff app to work with kernel displays
- Fix for `lvgl_try_lock()` timing
- Fix for touch events with slow updating displays
Improvements:
- `GuiService` now keeps trying to lock to prevent silent failures caused by drivers.
- `GuiService` now uses lvgl-module calls for locking/unlocking
- display driver now has capability `DISPLAY_CAPABILITY_SLOW_REFRESH`
* **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).
- Added kernel base drivers for: display, pointer (touch, mouse, etc.), keyboard, adc, power supply and backlight
- Implement new kernel driver modules: `st7789-module` and `gt911-module`
- Implement ESP32 ADC "oneshot" kernel driver
- Implement ESP32 backlight kernel driver with ledc API
- Implemented `battery-sense` driver that allows for voltage measurement and creates a power supply child device
- Updated github actions
- Updated flash scripts
- Fix for esp32 legacy driver conflict with ADC
- Created separate `lilygo-tdeck` and `lilygo-tdeck-plus` devices
- Created `lilygo-module` with LilyGO kernel drivers
- Fix for intermittent errors in build related to code generation of `devicetree.c`
- `lvgl-module` can now map kernel drivers onto LVGL devices
- Created `KernelDisplayApp` as a mirror of `HalDisplayApp` (formerly `DisplayApp`)
- Removed `struct` and `enum` prefix in a lot of kernel driver cpp source files
- `lilygo-tdeck` and `lilygo-tdeck-plus` are now fully relying on kernel drivers and don't use any of the old HAL
