Hi, Here is an attempt at getting the HDMI controller running. This HDMI controller is found on a number of old Allwinner SoCs (A10, A10s, A20, A31). This driver only supports for now the A10s because it was an easy target, being very close to the A13 that is already supported by our DRM driver. There's nothing out of the extraordinary there, except maybe the clock setup. All the internal clocks (TMDS, DDC) have been modeled using the common clock framework, the TMDS clock being the parent of the DDC one. While this might sound overkill, other SoC have a different, external source for the DDC clock, which will be easier to support through the clock framework. It's still a bit rough around the edges, as it doesn't work for all the modes. This will need to be fixed before being merged obviously. The IP also supports audio (through an already supported i2s controller, and some missing configuration in the HDMI controller) and CEC. Both will come eventually. Let me know what you think!
