There is no hpd-gpio installed on the CI20 board HDMI connector. Hence there is no hpd detection by the connector driver and we have to enable polling by the dw-hdmi driver. We need to set .poll_enabled but that struct component can only be accessed in the core code. Hence we use the public setter function drm_kms_helper_hotplug_event(). Signed-off-by: H.
