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.
