This deserializer can be used with sensors that directly produce a
10-bit LVDS stream and converts it to a parallel bus.
Controlling it via the optional GPIOs is mainly useful for avoiding
conflicts when another parallel sensor is connected to the same data bus
as the deserializer.

+TI SCAN921226H Video Deserializer
+---------------------------------
+
+The SCAN921226H receives a LVDS serial data stream with embedded clock and
+converts it to a 10-bit wide parallel data bus and recovers parallel clock.
+Some CMOS sensors such as the ON Semiconductor MT9V024 produce a LVDS signal
+compatible with this deserializer.
+
+Required properties:
+- compatible : should be "ti,scan921226h"
+- #address-cells: should be <1>
+- #size-cells: should be <0>
+- port@0: serial (LVDS) input
+- port@1: parallel output
+
+The device node should contain two 'port' child nodes (one each for input and
+output), in accordance with the video interface bindings defined in
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Optional Properties:
+- enable-gpios: reference to the GPIO connected to the REN (output enable) pin,
+ if any.
+- npwrdn-gpios: reference to the GPIO connected to the nPWRDN pin, if any.
+
+Optionally, #address-cells, #size-cells, and port nodes can be grouped under a
+ports node as described in Documentation/devicetree/bindings/graph.txt.
+
+Example:
+
+ csi0_deserializer: csi0_deserializer {
+ compatible = "ti,scan921226h";
+
+ enable-gpios = <&gpio5 20 GPIO_ACTIVE_HIGH>;
+ npwrdn-gpios = <&gpio1 24 GPIO_ACTIVE_HIGH>;
+
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ /* serial sink interface */
+ port@0 {
+ reg = <0>;
+
+ des0_in: endpoint {
+ remote-endpoint = <&mt9v024_0_out>;
+ };
+ };
+
+ /* parallel source interface */
+ port@1 {
+ reg = <1>;
+
+ des0_out: endpoint {
+ remote-endpoint = <&ipu1_csi0_mux_from_parallel_sensor>;
+ bus-width = <8>;
+ hsync-active = <1>;
+ vsync-active = <1>;
+ };
+ };
+ };
