-Renesas Capture Engine Unit (CEU)
-----------------------------------------------
-
-The Capture Engine Unit is the image capture interface found in the Renesas
-SH Mobile, R-Mobile and RZ SoCs.
-
-The interface supports a single parallel input with data bus width of 8 or 16
-bits.
-
-Required properties:
-- compatible: Shall be one of the following values:
- "renesas,r7s72100-ceu" for CEU units found in RZ/A1H and RZ/A1M SoCs
- "renesas,r8a7740-ceu" for CEU units found in R-Mobile A1 R8A7740 SoCs
-- reg: Registers address base and size.
-- interrupts: The interrupt specifier.
-
-The CEU supports a single parallel input and should contain a single 'port'
-subnode with a single 'endpoint'. Connection to input devices are modeled
-according to the video interfaces OF bindings specified in:
-[1] Documentation/devicetree/bindings/media/video-interfaces.txt
-
-Optional endpoint properties applicable to parallel input bus described in
-the above mentioned "video-interfaces.txt" file are supported.
-
-- hsync-active: See [1] for description. If property is not present,
- default is active high.
-- vsync-active: See [1] for description. If property is not present,
- default is active high.
-- bus-width: See [1] for description. Accepted values are '8' and '16'.
- If property is not present, default is '8'.
-- field-even-active: See [1] for description. If property is not present,
- an even field is identified by a logic 0 (active-low signal).
-
-Example:
-
-The example describes the connection between the Capture Engine Unit and an
-OV7670 image sensor connected to i2c1 interface.
