Another thing is that CONFIG_DRM_AUX_HPD_BRIDGE originally needed to be

Sorry, I don't understand the problem here? What do you need to expose
in Kconfig?

config DRM_AUX_HPD_BRIDGE
    tristate
    depends on DRM_BRIDGE && OF
    select AUXILIARY_BUS
    help
      Simple bridge that terminates the bridge chain and provides HPD
      support.

The tristate here is empty, so now it can only be selected by some TypeC controller drivers. I think it's not a big deal, just expose this item.



thanks,
