rk3066_hdmi.c calls drm_bridge_connector_init(), but ROCKCHIP_RK3066_HDMI selects neither DRM_BRIDGE_CONNECTOR nor DRM_DISPLAY_HELPER, whose module carries the bridge-connector code. A configuration with ROCKCHIP_RK3066_HDMI as the only enabled Rockchip output option fails to link: aarch64-linux-gnu-ld: drivers/gpu/drm/rockchip/rk3066_hdmi.o: in function `rk3066_hdmi_bind': rk3066_hdmi.c:(.text+0x7a4): undefined reference to `drm_bridge_connector_init' aarch64-linux-gnu-ld: drivers/gpu/drm/rockchip/rk3066_hdmi.o: in function `rk3066_hdmi_bridge_atomic_enable': rk3066_hdmi.c:(.text+0xe74): undefined reference to `drm_atomic_helper_connector_hdmi_update_infoframes' Select both, like ROCKCHIP_CDN_DP, ROCKCHIP_LVDS and ROCKCHIP_RGB do. DRM_BRIDGE_CONNECTOR in turn selects DRM_DISPLAY_HDMI_STATE_HELPER, which resolves the second symbol.
