Could you also provide the opp table for op1-variants please?


Thanks

this is missing a separate patch adding rockchip,rk3399-mali to 
	Documentation/devicetree/bindings/gpu/arm,mali-midgard.txt

Also arm,mali-midgard is not part of the binding. I just saw that it slipped
into the example in the binding file and also the rk3288.dtsi - which should
be fixed. But the driver should bind against the arm,mali-t860 alone, not
the mali-midgard.
