1* MediaTek JPEG Encoder 2 3MediaTek JPEG Encoder is the JPEG encode hardware present in MediaTek SoCs 4 5Required properties: 6- compatible : "mediatek,mt2701-jpgenc" 7 followed by "mediatek,mtk-jpgenc" 8- reg : physical base address of the JPEG encoder registers and length of 9 memory mapped region. 10- interrupts : interrupt number to the interrupt controller. 11- clocks: device clocks, see 12 Documentation/devicetree/bindings/clock/clock-bindings.txt for details. 13- clock-names: must contain "jpgenc". It is the clock of JPEG encoder. 14- power-domains: a phandle to the power domain, see 15 Documentation/devicetree/bindings/power/power_domain.txt for details. 16- mediatek,larb: must contain the local arbiters in the current SoCs, see 17 Documentation/devicetree/bindings/memory-controllers/mediatek,smi-larb.yaml 18 for details. 19- iommus: should point to the respective IOMMU block with master port as 20 argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.yaml 21 for details. 22 23Example: 24 jpegenc: jpegenc@1500a000 { 25 compatible = "mediatek,mt2701-jpgenc", 26 "mediatek,mtk-jpgenc"; 27 reg = <0 0x1500a000 0 0x1000>; 28 interrupts = <GIC_SPI 141 IRQ_TYPE_LEVEL_LOW>; 29 clocks = <&imgsys CLK_IMG_VENC>; 30 clock-names = "jpgenc"; 31 power-domains = <&scpsys MT2701_POWER_DOMAIN_ISP>; 32 mediatek,larb = <&larb2>; 33 iommus = <&iommu MT2701_M4U_PORT_JPGENC_RDMA>, 34 <&iommu MT2701_M4U_PORT_JPGENC_BSDMA>; 35 }; 36
