I wanted you asked me about this to ask you:
if I can't test it on HW, but others tested it all around,
for example using this patch:
https://github.com/armbian/build/blob/master/patch/kernel/sunxi-next/32-h3-DT-add-mali-node.patch

Is it enough? Or do I have to test it directly?
Or maybe I can invite those people to tag this patch as tested-by ?

Yes, H5 has dual GPU but quad PP and on IRQ you can clearly see:
- GPU_GP
- GPU_GPMMU
- GPU_PMU
- GPU_PP
- GPU_PP0
- GPU_PPMMU0
- GPU_PP1
- GPU_PPMMU1
- GPU_PP2
- GPU_PPMMU2
- GPU_PP3
- GPU_PPMMU3

So I think they should be placed in specific dts files.
What do you think?

Thanks
