OK, I see.
The Samsung Exynos eDP contoller and Rockchip rk3288 eDP contoller share
the same IP. So, a lot of parts can be re-used. I agree with this.
However, we have to review the code carefully, as others did.
I also cannot find the exact IP name. The "analogix" may be the vendor name
of this IP.
