Add Marvell MMP2 camera host interface.
Signed-off-by: Lubomir Rintel <lkundrak@xxxxx>
---
Changes since v3:
- Dropped the video-interfaces.txt reference
- Clarify "clocks", "clock-names" and "clock-output-names" descriptions
- Refer to other documentation by full path
Changes since v2:
- Added #clock-cells, clock-names, port

+Marvell MMP2 camera host interface
+
+Required properties:
+ - compatible: Should be "marvell,mmp2-ccic".
+ - reg: Register base and size.
+ - interrupts: The interrupt number.
+ - #clock-cells: Nust be 0.
+
+Optional properties:
+ - clocks: Reference to the input clock as specified by
+ Documentation/devicetree/bindings/clock/clock-bindings.txt.
+ - clock-names: Names of the clocks used; "axi" for the AXI bus interface,
+ "func" for the peripheral clock and "phy" for the parallel
+ video bus interface.
+ - clock-output-names: Optional clock source for sensors. Shall be "mclk".
+
+Required subnodes:
+ - port: The parallel bus interface port with a single endpoint linked to
+ the sensor's endpoint as described in
+ Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example:
+
+ camera0: camera@d420a000 {
+ compatible = "marvell,mmp2-ccic";
+ reg = <0xd420a000 0x800>;
+ interrupts = <42>;
+ clocks = <&soc_clocks MMP2_CLK_CCIC0>;
+ clock-names = "axi";
+ #clock-cells = <0>;
+ clock-output-names = "mclk";
+
+ port {
+ camera0_0: endpoint {
+ remote-endpoint = <&ov7670_0>;
+ };
+ };
+ };
