+Marvell PXA camera host interface
+
+Required properties:
+ - compatible: Should be "marvell,pxa270-qci"
+ - reg: register base and size
+ - interrupts: the interrupt number
+ - any required generic properties defined in video-interfaces.txt
+
+Optional properties:
+ - clocks: input clock (see clock-bindings.txt)
+ - clock-output-names: should contain the name of the clock driving the
+ sensor master clock MCLK
+ - clock-frequency: host interface is driving MCLK, and MCLK rate is this rate
+
+Example:
+
+ pxa_camera: pxa_camera@50000000 {
+ compatible = "marvell,pxa270-qci";
+ reg = <0x50000000 0x1000>;
+ interrupts = <33>;
+
+ clocks = <&pxa2xx_clks 24>;
+ clock-names = "ciclk";
+ clock-frequency = <50000000>;
+ clock-output-names = "qci_mclk";
+
+ status = "okay";
+
+ port {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ /* Parallel bus endpoint */
+ qci: endpoint@0 {
+ reg = <0>; /* Local endpoint # */
+ remote-endpoint = <&mt9m111_1>;
+ bus-width = <8>; /* Used data lines */
+ hsync-active = <0>; /* Active low */
+ vsync-active = <0>; /* Active low */
+ pclk-sample = <1>; /* Rising */
+ };
+ };
+ };
