In your board device tree it should look somewhat like this:
&i2c1 {
sensor@48 {
compatible = "aptina,mt9v032m";
/* ... */
port {
cam_out: endpoint {
remote-endpoint = <&csi_in>;
}
};
};
};
/*
* This is the input port node corresponding to the 'CSI0' pad group,
* not necessarily the CSI0 port of IPU1 or IPU2. On i.MX6Q it's port@1
* of the mipi_ipu1_mux, on i.MX6DL it's port@4 of the ipu_csi0_mux,
* the csi0 label is added in patch 13/21.
*/
&csi0 {
#address-cells = <1>;
#size-cells = <0>;
csi_in: endpoint@0 {
bus-width = <8>;
data-shift = <12>;
hsync-active = <1>;
vsync-active = <1>;
pclk-sample = <1>;
remote-endpoint = <&cam_out>;
};
};

Thank you, that is a leftover from stripping down the driver to the
basics. I'll test with a grayscale camera and fix this in the next
version.
