+STMicroelectronics MIPID02 CSI-2 to PARALLEL bridge
+
+MIPID02 has two CSI-2 input ports, only one of those ports can be active at a
+time. Active port input stream will be de-serialized and its content outputted
+through PARALLEL output port.
+CSI-2 first input port is a dual lane 800Mbps whereas CSI-2 second input port is
+a single lane 800Mbps. Both ports support clock and data lane polarity swap.
+First port also supports data lane swap.
+PARALLEL output port has a maximum width of 12 bits.
+Supported formats are RAW6, RAW7, RAW8, RAW10, RAW12, RGB565, RGB888, RGB444,
+YUV420 8-bit, YUV422 8-bit and YUV420 10-bit.
+
+Required Properties:
+- compatible: should be "st,st-mipid02"
+- clocks: reference to the xclk input clock.
+- clock-names: should be "xclk".
+- VDDE-supply: sensor digital IO supply. Must be 1.8 volts.
+- VDDIN-supply: sensor internal regulator supply. Must be 1.8 volts.
+
+Optional Properties:
+- reset-gpios: reference to the GPIO connected to the xsdn pin, if any.
+ This is an active low signal to the mipid02.
+
+Required subnodes:
+ - ports: A ports node with one port child node per device input and output
+ port, in accordance with the video interface bindings defined in
+ Documentation/devicetree/bindings/media/video-interfaces.txt. The
+ port nodes are numbered as follows:
+
+ Port Description
+ -----------------------------
+ 0 CSI-2 first input port
+ 1 CSI-2 second input port
+ 2 PARALLEL output
+
+Example:
+
+mipid02: mipid02@14 {
+ compatible = "st,st-mipid02";
+ reg = <0x14>;
+ status = "okay";
+ clocks = <&clk_ext_camera_12>;
+ clock-names = "xclk";
+ VDDE-supply = <&vdd>;
+ VDDIN-supply = <&vdd>;
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ port@0 {
+ reg = <0>;
+
+ ep0: endpoint {
+ clock-lanes = <0>;
+ data-lanes = <1 2>;
+ remote-endpoint = <&mipi_csi2_in>;
+ };
+ };
+ port@2 {
+ reg = <2>;
+
+ ep2: endpoint {
+ bus-width = <8>;
+ hsync-active = <0>;
+ vsync-active = <0>;
+ remote-endpoint = <¶llel_out>;
+ };
+ };
+ };
+};
