+* Mediatek Face Detection Unit (FD)
+
+Face Detection (FD) unit is a typical memory-to-memory HW device.
+It provides hardware accelerated face detection function, and it
+is able to detect different poses of faces. FD will writre result
+of detected face into memory as output.
+
+Required properties:
+- compatible: "mediatek,mt8183-fd"
+- mediatek,scp : the node of system control processor (SCP), see
+  Documentation/devicetree/bindings/remoteproc/mtk,scp.txt for details.
+- iommus: should point to the 3 entries:  M4U_PORT_CAM_FDVT_RP,
+  M4U_PORT_CAM_FDVT_WR and M4U_PORT_CAM_FDVT_RB.  (Please see
+  Documentation/devicetree/bindings/iommu/mediatek,iommu.txt for details.)
+- reg: Physical base address and length of the register space.
+- interrupts: interrupt number to the cpu.
+- clocks : must contain the FDVT clock, see
+  Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
+- clock-names: must be "fd".
+- power-domain: must be "MT8183_POWER_DOMAIN_ISP".
+
+Example:
+	fd: fd@1502b000 {
+		compatible = "mediatek,mt8183-fd";
+		mediatek,scp = <&scp>;
+		iommus = <&iommu M4U_PORT_CAM_FDVT_RP>,
+			 <&iommu M4U_PORT_CAM_FDVT_WR>,
+			 <&iommu M4U_PORT_CAM_FDVT_RB>;
+		reg = <0 0x1502b000 0 0x1000>;
+		interrupts = <GIC_SPI 269 IRQ_TYPE_LEVEL_LOW>;
+		clocks = <&imgsys CLK_IMG_FDVT>;
+		clock-names = "fd";
+		power-domains = <&scpsys MT8183_POWER_DOMAIN_ISP>;
+	};
