Dynamically change enumeration list of DRM enumeration property

Hi, Is it possible to dynamically change enumeration list of DRM enumeration property ? Motivation behind this question is to understand whether it is possible to create connector enum property (e.g a property which will list supported output encodings - like yuv420, yuv422 etc) whose list of su

When validating a mode, bridges may need to do so in the context of a display, as specified by drm_display_info. An example is the meson dw-hdmi bridge that needs to consider the YUV 4:2:0 output format to perform clock calculations. Bridges that need the display info currently retrieve it from th
