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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
