ARM Mali Utgard GPU =================== Required properties: - compatible * Must be one of the following: + "arm,mali-300" + "arm,mali-400" + "arm,mali-450" * And, optionally, one of the vendor specific compatible: + allwinner,sun4i-a10-mali + allwinner,sun7i-a20-mali + allwinner,sun8i-h3-mali + allwinner,sun50i-h5-mali + amlogic,meson-gxbb-mali + amlogic,meson-gxl-mali + rockchip,rk3036-mali + rockchip,rk3066-mali + rockchip,rk3188-mali + rockchip,rk3228-mali + rockchip,rk3328-mali + stericsson,db8500-mali - reg: Physical base address and length of the GPU registers - interrupts: an entry for each entry in interrupt-names. See ../interrupt-controller/interrupts.txt for details. - interrupt-names: * ppX: Pixel Processor X interrupt (X from 0 to 7) * ppmmuX: Pixel Processor X MMU interrupt (X from 0 to 7) * pp: Pixel Processor broadcast interrupt (mali-450 only) * gp: Geometry Processor interrupt * gpmmu: Geometry Processor MMU interrupt - clocks: an entry for each entry in clock-names - clock-names: * bus: bus clock for the GPU * core: clock driving the GPU itself Optional properties: - interrupt-names and interrupts: * pmu: Power Management Unit interrupt, if implemented in hardware - memory-region: Memory region to allocate from, as defined in Documentation/devicetree/bindi/reserved-memory/reserved-memory.txt - mali-supply: Phandle to regulator for the Mali device, as defined in Documentation/devicetree/bindings/regulator/regulator.txt for details. - operating-points-v2: Operating Points for the GPU, as defined in Documentation/devicetree/bindings/opp/opp.txt - power-domains: A power domain consumer specifier as defined in Documentation/devicetree/bindings/power/power_domain.txt Vendor-specific bindings ------------------------ The Mali GPU is integrated very differently from one SoC to another. In order to accomodate those differences, you have the option to specify one more vendor-specific compatible, among: - allwinner,sun4i-a10-mali Required properties: * resets: phandle to the reset line for the GPU - allwinner,sun7i-a20-mali Required properties: * resets: phandle to the reset line for the GPU - allwinner,sun50i-h5-mali Required properties: * resets: phandle to the reset line for the GPU - Rockchip variants: Required properties: * resets: phandle to the reset line for the GPU - stericsson,db8500-mali Required properties: * interrupt-names and interrupts: + combined: combined interrupt of all of the above lines Example: mali: gpu@1c40000 { compatible = "allwinner,sun7i-a20-mali", "arm,mali-400"; reg = <0x01c40000 0x10000>; interrupts = , , , , , , ; interrupt-names = "gp", "gpmmu", "pp0", "ppmmu0", "pp1", "ppmmu1", "pmu"; clocks = <&ccu CLK_BUS_GPU>, <&ccu CLK_GPU>; clock-names = "bus", "core"; resets = <&ccu RST_BUS_GPU>; };
