All of imx*.dts* use gpu: or gpu2d:/gpu3d:/vpuvg: for the GPU label. I see allwinner does use mali: label, but maybe it would be better to stay consistent with the i.MX labels ? Also, variants of gpu: label seems more popular: linux$ grep -hro '[a-z0-9_]\+: gpu@' arch/ | sort | uniq -c 3 adreno_gpu: gpu@ 1 bb2d: gpu@ 1 gpu2d: gpu@ 1 gpu3d: gpu@ 80 gpu: gpu@ 4 gpu_2d: gpu@ 1 gpu_3d0: gpu@ 4 gpu_3d: gpu@ 6 gpu_mem: gpu@ 1 gpu_reserved: gpu@ 2 gpu_vg: gpu@ 17 mali: gpu@ 1 v3d: gpu@ 2 zap_shader_region: gpu@
