I don't, unfortunately. It looks like their products use Mali 400 MP2 GPUs, which seems to have support via Lima. I had several boards with Mali-T628's, and while they work, I ran into headaches a lot a 6+ years ago, like issues with GPU accelerated video, browsing in Chromium and desktop compositing. I've heard from developers that work on those boards that the GPU support is much better than it was a half decade ago, though.

Personally, I won't be buying more ARM SoCs unless they start supporting SBSA and have mainline kernel support for all of their peripherals. As it stands, the only hardware that I'm aware of that has full mainline support for everything, including GPUs, are boards with Intel iGPUs or AMD APUs.
