Hi all, This series adds DRM support for the Display Control Unit (DCU) found in Nuvoton MA35D1 SoCs.
The DCU is a DPI-based display controller intended to be used with external panels or bridges. The driver integrates with the DRM bridge framework and supports atomic modesetting. The series consists of three patches: Add Device Tree binding documentation for the MA35D1 DCU Enable the display controller in the MA35D1 SoC dtsi and SOM dts Add the DRM driver for the MA35D1 display controller This has been tested using modetest with a DPI panel and verified to expose modes and perform atomic modesetting correctly.
