A200 driver submission for Linux mainline kernel

[abhijit]

Hi Lucas,

Thank you very much for reply.

The driver is already integrated with new kernel frame-work and tested 
with 4.14.1 kernel with KGSL interface.

There are some patches for MESA and libdrm patches though

I am planning for pushing MESA and DRM patches later. Are you implying 
to push MESA and libdrm specific changes first?

Regards,

   Abhijit
