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"; > + reg = <0x0 0xff9a0000 0x0 0x10000>; > + interrupts = <GIC_SPI 19 IRQ_TYPE_LEVEL_HIGH 0>, > + <GIC_SPI 20 IRQ_TYPE_LEVEL_HIGH 0>, > + <GIC_SPI 21 IRQ_TYPE_LEVEL_HIGH 0>; > + interrupt-names = "GPU", "JOB", "MMU"; interrupt names are job, mmu, gpu in lower case.
