+* Mediatek seninf MIPI-CSI2 host driver
+
+Seninf MIPI-CSI2 host driver is a HW camera interface controller. It support a widely adopted,
+simple, high-speed protocol primarily intended for point-to-point image and video
+transmission between cameras and host devices.
+
+Required properties:
+  - compatible: "mediatek,mt8183-seninf"
+  - reg: Must contain an entry for each entry in reg-names.
+  - reg-names: Must include the following entries:
+    "base_reg": seninf registers base
+    "rx_reg": Rx analog registers base
+  - interrupts: interrupt number to the cpu.
+  - clocks : clock name from clock manager
+  - clock-names: must be CLK_CAM_SENINF and CLK_TOP_MUX_SENINF.
+    It is the clocks of seninf
+
+Example:
+	seninf: seninf at 1a040000 {
+		compatible = "mediatek,mt8183-seninf";
+		reg = <0 0x1a040000 0 0x8000>,
+		      <0 0x11C80000 0 0x6000>;
+		reg-names = "base_reg", "rx_reg";
+		interrupts = <GIC_SPI 251 IRQ_TYPE_LEVEL_LOW>;
+		power-domains = <&scpsys MT8183_POWER_DOMAIN_CAM>;
+		clocks =
+				<&camsys CLK_CAM_SENINF>, <&topckgen CLK_TOP_MUX_SENINF>;
+		clock-names =
+			"CLK_CAM_SENINF", "CLK_TOP_MUX_SENINF";
+	}
