The imx6sl soc has gpu_2d and gpu_vg, no 3d support:
etnaviv-gpu 2200000.gpu: model: GC320, revision: 5007 etnaviv-gpu 2204000.gpu: model: GC355, revision: 1215
The IP blocks are close enough to supported hardware that they "just work" with etnaviv and x11.
According to the kernel log above, they aren't just close enough, but actually the same revision as the cores on the i.MX6Q.

I think this DT is ordered by unit address, so both GPU nodes should move to the end of the dts file, right?

Tested by using yocto fsl community bsp built in "mainline" mode. This patch makes x11 start up and turning on drm.debug shows that the etnaviv driver is being used.
I don't know if such a patch requires much more testing: all it really does is "describe the hardware".
Patch is against shawguo/imx/dt, it depends on newly accepted commit 13211eec7b0e ("ARM: dts: imx6sl: Convert gpc to new bindings") This is only because of the way it references the PU power domain.
