[Freedreno] Add support for DisplayPort driver on SnapDragon 845 - 5.2.0 kernel from Linaro.

Tue Nov 12 10:21:06 UTC 2019

Hi Chandan,

I am trying to enable DP on 5.2.0 based kernel from Linaro, using Inforce
Computing SnapDragon 845 based board. I have integrated your DP patches
done on 4.9 kernel.
I am getting some compile errors as listed below. Please let me know if you
have some pointers for that, also do you have plans to integrate on 5.2
kernel? Please let me know.
