Maybe you have an idea what is going wrong there?
Empirically we have managed to find that after bypassing the Video Processor and using the Mixer alone [1], LCD0 power domain is no longer needed for HDMI operation. However there is still an issue with power-up and/or -down sequences causing the whole system to hang when trying to power on and off HDMI repeatedly. This is to be investigated yet. [1] This can be achieved by setting .is_vp_enabled of exynos4210_mxr_drv_data to 0, assuming that you have a patch applied which adds appropriate compatible string to mixer_match_types[], pointing to that struct.
