- 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
