[Freedreno] Whether A200 driver is supported by Linux Mainline Kernel

[abhijit]

Hi Waldimir,

Hi Wladimir,

Can you please let me know if you have any plans to make changes for 
A200 mainline?

I have ported the KGSL driver along with other source files to 4.14.1 
kernel and got it working. Can you let me know, if I can commit the code 
to your repository?

Regards,
    Abhijit
