Hi Alex,
I did try to not touching hantro driver code and just enabling the node in
devicetree by a compatible property like:
compatible = "rockchip,rk3588-vpu", "rockchip,rk3568-vpu";
but the hantro g1 node is not binded by hantro driver. I guess that is
because hantro driver is already binded to the hantro av1 vpu on rk3588,
so I added patch[1/3] to make it work.
