Dmesg shows also "Initialized etnaviv 1.3.0 20151214 for etnaviv on minor 0" and "  Initialized imx-drm 1.0.0 20120507 for display-subsystem on minor 1". So I expect both kernel drivers to work.

It's better not to use the NXP kernel at all if you want to use Etnaviv.

Just use a mainline kernel from kernel.org with the
imx_v6_v7_defconfig, boot it, and the Etnaviv driver will be loaded by
default.

You can then try to run the 'kmscube' application to confirm that the
driver is functional.
