    +* MediaTek JPEG Encoder
    +
    +MediaTek JPEG Encoder is the JPEG encode hardware present in MediaTek SoCs
    +
    +Required properties:
    +- compatible : "mediatek,mt2701-jpgenc"
    + followed by "mediatek,mtk-jpgenc"
    +- reg : physical base address of the JPEG encoder registers and length of
    + memory mapped region.
    +- interrupts : interrupt number to the interrupt controller.
    +- clocks: device clocks, see
    + Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
    +- clock-names: must contain "jpgenc". It is the clock of JPEG encoder.
    +- power-domains: a phandle to the power domain, see
    + Documentation/devicetree/bindings/power/power_domain.txt for details.
    +- mediatek,larb: must contain the local arbiters in the current SoCs, see
    + Documentation/devicetree/bindings/memory-controllers/mediatek,smi-larb.txt
    + for details.
    +- iommus: should point to the respective IOMMU block with master port as
    + argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.txt
    + for details.
    +
    +Example:
    + jpegenc: jpegenc@1500a000 {
    + compatible = "mediatek,mt2701-jpgenc",
    + "mediatek,mtk-jpgenc";
    + reg = <0 0x1500a000 0 0x1000>;
    + interrupts = <GIC_SPI 141 IRQ_TYPE_LEVEL_LOW>;
    + clocks = <&imgsys CLK_IMG_VENC>;
    + clock-names = "jpgenc";
    + power-domains = <&scpsys MT2701_POWER_DOMAIN_ISP>;
    + mediatek,larb = <&larb2>;
    + iommus = <&iommu MT2701_M4U_PORT_JPGENC_RDMA>,
    + <&iommu MT2701_M4U_PORT_JPGENC_BSDMA>;
    + };
