A specialisation of the generic Synopsys HDMI driver is employed for JZ4780 HDMI support. This requires a new driver, plus device tree and configuration modifications. Here we add Kconfig DRM_INGENIC_DW_HDMI, Makefile and driver code. Note that 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 in the dw-hdmi core driver. For that we need to set .poll_enabled but that struct component can only be accessed by core code. Hence we use the public setter function drm_kms_helper_hotplug_event() introduced before. Also note that we disable Color Space Conversion since it is not working on jz4780.
