+* MediaTek JPEG Encoder
+
+MediaTek JPEG Encoder is the JPEG encode hardware present in MediaTek SoCs
+
+Required properties:
+- compatible : should be one of:
+ "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>;
+ };
