+* 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".
+
+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";
+ };
