[meta-freescale] linux-imx 4.9 EGLFS support

[Jeff Horn]

I am facing the same problem. I am trying to move my BSP to rocko. I ported
my custom kernel patches to the LTS 4.9 kernel and I would like to use the
LTS 5.9 Qt. What are the newer Vivante driver versions? It looks like in
rocko the imx-gpu-viv is 5.0.11.

Thanks,
Jeff
