so the 'gpu-subsystem' comes from etnaviv:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/display/etnaviv/etnaviv-drm.txt?id=refs/tags/v4.9-rc5
For a generic name, it's currently only tied to the etnaviv driver:
gpu-subsystem {
compatible = "fsl,imx-gpu-subsystem";
cores = <&gpu_2d>, <&gpu_3d>;
};
it would make sense to make that more generic, so you could tie a 2d
vivante and a imgtec/sgx 3d core.. <sad laugh> but that would require
adding a imgtec/sgx driver/bindings to the kernel mainline... </sad
