sorry for my delay, I need to build the source code and modify the driver to test for you, now, I can boot up the camera on the second port, so I think mipi csi can read the second port, you can find my result, the dts I modify as below, I only have os08a0 camera, so I attach this camera with port@1
1)dts file:
&mipi_csi_0 {
status = "okay";
port@0 {
reg = <0>;
mipi_ep: endpoint {
remote-endpoint = <&ov5640_mipi1_ep>;
data-lanes = <2>;
csis-hs-settle = <10>;
};
};
port@1 {
reg = <1>;
endpoint {
remote-endpoint = <&os08a20_mipi_0_ep>;
data-lanes = <4>;
csis-hs-settle = <16>;
};
};
2) then I add the mipi csi driver to search the second port
node1 = of_graph_get_next_endpoint(node, NULL);
node = of_graph_get_next_endpoint(node, node1);
3) you also need to change the imx8-media-dev.c
/* csi2 node have only port */
// port = of_get_next_child(node, NULL); //joan
port1 = of_get_next_child(node, NULL);//joan
port = of_get_next_child(node, port1);//joan
v4l2_info(&mxc_md->v4l2_dev,
"port name is %s\n", port->full_name);
I add print information, can find the name from logfile as below
4) don't forget change the "else if (mxc_md->mipi_csi2[sensor->id].sd) " to
"else if (mxc_md->mipi_csi2[0].sd) " and change "mipi_csi2 = &mxc_md->mipi_csi2[sensor->id];“ to
"mipi_csi2 = &mxc_md->mipi_csi2[0];"
and don't forget you need reload imx8-media-dev.ko again after you build this driver
the result you can find
