The proposed DRM driver works on a Orange PI 2 with a kernel 4.4-rc1 and the H3 patches found in Hans de Goede's GIT repository.
As there is no documentation about the DE2 nor about the HDMI which are found in the H3, this driver has been built from Allwiiner's sources.
So, there may be license problems, especially for the file de2_hdmi_h3.c which contains a lot of magic values.
The associated DT and documentation will be submitted when the H3 DTs will be in the kernel.
