no wildcards and correct compatibles please.
The binding specifies arm,mali-t860 for your chip and the soc
specific compatible needs a rockchip vendor, so you need

	compatible = "rockchip,rk3399-mali", "arm,mali-t860";

interrupt names are job, mmu, gpu in lower case. The out-of-tree driver
will need to conform to that.

no clock-names property, as midgard malis only have one clock input
