Thank you for your reply.
Is it only the kernel that needs to be patched?
I've tried to use the kernel with the all the Congatec provided patches,
but it still won't work.

Do you think a port of the patch "linux-wandboard: Add support to
Vivante 4.6.9p12 GPU code" would fix the problem?

Anyway, I will check with the Congatec support and thanks again for your
help.
