To achieve this, the current driver (previously restricted to DSI) is refactored to support both DSI and SPI variants independently. The series includes: - A refactoring of the existing driver and Kconfig to support multiple buses. - DT binding documentation for the Rocktech RK050HR345-CT106A. - The implementation of the SPI-based driver for the Rocktech panel. Changes in v5: - Add Reviewed-by tag of Neil Armstrong for patches: - 1/4 drm/panel: ilitek-ili9806e: rename to specific DSI driver - 2/4 drm/panel: ilitek-ili9806e: split core and DSI logic Changes in v4: - Fix "WARNING: unmet direct dependencies detected for DRM_PANEL_ILITEK_ILI9806E_CORE" reported by kernel test robot Changes in v3: - Add Reviewed-by tag of Rob Herring Changes in v2: - Introduce DRM_PANEL_ILITEK_ILI9806E_CORE hidden kconfig option. - Split core and DSI logic. - Restore vdd-supply as required for both DSI and SPI types in the dt-bindings. - Dop useless settings in case of rocktech,rk050hr345-ct106a in the dt-bindings.
