- `DisplayDevice` improvements related `DisplayDriver` - Replaced incorrect usage of `spiBusHandle` with `spiHostDevice` in all SPI display devices - Disabled `DisplayDriver` support for RGB displays for now - Updated `GraphicsDemo` project for the above changes - TactilityC improvements: - created `tt_hal_device_find()` - created `tt_hal_display_*` - created `tt_hal_touch_*` - created `tt_lvgl_*` - export `tt_app_*` calls
