From the linux discussion, I recall that you said that the TCON was
still the same, and the HDMI was something that could be shared with
the Rockchip implementation. Did you look into sharing the TCON code
(for example using a small "library" to share the functions) and to
reuse Rockchip's HDMI code?

Thanks,
Maxime
