Recently I have been experimenting with the stock 4.14.x kernel code from kernel.org on my ROCK64 (with no patches at all). 4.14 boots up ok although HDMI doesn't work. Serial console and ethernet both work.
The 4.14 kernel does need the dtb that is generated from the 4.14 build. You must update both the kernel and dtb to the 4.14 versions created in the 4.14 build for it to work. If you try to boot the 4.14 kernel without updating the dtb also, it doesn't work.
I took a shot at porting the mali code to 4.14. WIth some changes to the mali code I got it incorporated into my kernel but I still don't get any HDMI output. I don't know much about graphics but there may be more pieces needed before HDMI works.
