Xilinx Video Demosaic IP
-----------------------------
The Xilinx Video Demosaic IP is used to interface to a Bayer video source.
The driver set default Sink Pad media bus format to RGGB.
The IP and driver only support RGB as its Source Pad media format.
Required properties:
- compatible: Must be "xlnx,v-demosaic".
- reg: Physical base address and length of the registers set for the device.
- clocks: Reference to the AXI Streaming clock feeding the Demosaic ap_clk.
- xlnx,max-height: Maximum number of lines. Valid range is 64 to 4320.
- xlnx,max-width: Maximum number of pixels in a line. Valid range is 64 to 8192.
- reset-gpios: Specifier for GPIO that asserts Demosaic IP (AP_RST_N) reset.
- ports: Video ports, using the DT bindings defined in ../video-interfaces.txt.
Required port properties:
- reg: This value represents the media pad of the V4L2 sub-device.
A Sink Pad is represented by reg = <0>
A Source Pad is represented by reg = <1>
- xlnx,video-width: Video width as defined in video.txt
Example:
demosaic_1: demosaic@a00b0000 {
compatible = "xlnx,v-demosaic";
reg = <0x0 0xa00b0000 0x0 0x10000>;
clocks = <&vid_stream_clk>;
reset-gpios = <&gpio 87 1>;
xlnx,max-width = <3840>;
xlnx,max-height = <2160>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
xlnx,video-width = <8>;
demosaic_in: endpoint {
remote-endpoint = <&tpg_out>;
};
};
port@1 {
reg = <1>;
xlnx,video-width = <8>;
demosaic_out: endpoint {
remote-endpoint = <&gamma_in>;
};
};
};
};
