I tried your analogix_dp branch on an Exynos5800 Peach Pi Chromebook
but the machine didn't boot. Unfortunately I need to do some soldering
to have a serial console on this board so don't have a kernel boot log.

I'll let you know if I can get more info about this issue.

Also, there is Kconfig recursive dependency that you may want to fix:

$ make exynos_defconfig
drivers/video/fbdev/Kconfig:5:error: recursive dependency detected!
drivers/video/fbdev/Kconfig:5: symbol FB is selected by DRM_KMS_FB_HELPER
