1* Mediatek JPEG Decoder 2 3Mediatek JPEG Decoder is the JPEG decode hardware present in Mediatek SoCs 4 5Required properties: 6- compatible : must be one of the following string: 7 "mediatek,mt8173-jpgdec" 8 "mediatek,mt2701-jpgdec" 9- reg : physical base address of the jpeg decoder registers and length of 10 memory mapped region. 11- interrupts : interrupt number to the interrupt controller. 12- clocks: device clocks, see 13 Documentation/devicetree/bindings/clock/clock-bindings.txt for details. 14- clock-names: must contain "jpgdec-smi" and "jpgdec". 15- power-domains: a phandle to the power domain, see 16 Documentation/devicetree/bindings/power/power_domain.txt for details. 17- mediatek,larb: must contain the local arbiters in the current Socs, see 18 Documentation/devicetree/bindings/memory-controllers/mediatek,smi-larb.txt 19 for details. 20- iommus: should point to the respective IOMMU block with master port as 21 argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.txt 22 for details. 23 24Example: 25 jpegdec: jpegdec@15004000 { 26 compatible = "mediatek,mt2701-jpgdec"; 27 reg = <0 0x15004000 0 0x1000>; 28 interrupts = <GIC_SPI 143 IRQ_TYPE_LEVEL_LOW>; 29 clocks = <&imgsys CLK_IMG_JPGDEC_SMI>, 30 <&imgsys CLK_IMG_JPGDEC>; 31 clock-names = "jpgdec-smi", 32 "jpgdec"; 33 power-domains = <&scpsys MT2701_POWER_DOMAIN_ISP>; 34 mediatek,larb = <&larb2>; 35 iommus = <&iommu MT2701_M4U_PORT_JPGDEC_WDMA>, 36 <&iommu MT2701_M4U_PORT_JPGDEC_BSDMA>; 37 }; 38
