1 Renesas Capture Engine Unit (CEU)
2 ----------------------------------------------
4 The Capture Engine Unit is the image capture interface found in the Renesas
5 SH Mobile, R-Mobile and RZ SoCs.
7 The interface supports a single parallel input with data bus width of 8 or 16
11 - compatible: Shall be one of the following values:
12 "renesas,r7s72100-ceu" for CEU units found in RZ/A1H and RZ/A1M SoCs
13 "renesas,r8a7740-ceu" for CEU units found in R-Mobile A1 R8A7740 SoCs
14 - reg: Registers address base and size.
15 - interrupts: The interrupt specifier.
17 The CEU supports a single parallel input and should contain a single 'port'
18 subnode with a single 'endpoint'. Connection to input devices are modeled
19 according to the video interfaces OF bindings specified in:
20 Documentation/devicetree/bindings/media/video-interfaces.txt
22 Optional endpoint properties applicable to parallel input bus described in
23 the above mentioned "video-interfaces.txt" file are supported.
25 - hsync-active: Active state of the HSYNC signal, 0/1 for LOW/HIGH respectively.
26 If property is not present, default is active high.
27 - vsync-active: Active state of the VSYNC signal, 0/1 for LOW/HIGH respectively.
28 If property is not present, default is active high.
32 The example describes the connection between the Capture Engine Unit and an
33 OV7670 image sensor connected to i2c1 interface.
