Hello,
How to modify the kernel source code to support camera ?
I think I can add something about camera to device tree which can support camera ,but I don’t know the details how to modify the device tree.Please give me some tips.
Thank you very much.

And please refer to below link. Thanks.
hello SteveNv
This is the information in the device tree about camera,And i want to chage PAL camera to SDI camera
how to modify the device tree specifically
plugin-manager {
fragment-isl79987@0 {
ids = "isl-*";
override@0 {
_overlay_ {
status = "okay";
};
};
override@1 {
target = <&cam_module0>;
_overlay_ {
status = "okay";
badge = "isl79987_topleft_PSV27C";
position = "topleft";
orientation = "0";
};
};
override@2 {
target = <&cam_module0_drivernode0>;
_overlay_ {
status = "okay";
pcl_id = "v4l2_sensor";
devname = "isl79987 1-0044";
proc-device-tree = "/proc/device-tree/i2c@7000c400/isl79987_a@44";
};
};
override@3 {
target = <&cam_module0_drivernode1>;
_overlay_ {
status = "okay";
pcl_id = "v4l2_focuser_stub";
};
};
override@4 {
target = <&vi_port0>;
_overlay_ {
status = "okay";
};
};
override@5 {
target = <&isl79987_vi_in0>;
_overlay_ {
status = "okay";
csi-port = <0>;
bus-width = <2>;
remote-endpoint = <&isl_isl79987_out0>;
};
};
override@6 {
target = <&tcp>;
_overlay_ {
status = "okay";
num_csi_lanes = <2>;
max_pixel_rate = <160000>;
isp_peak_byte_per_pixel = <2>;
};
};
};
};
Thank you very much

Dear 2284810331,
I have a quick question.
May I know why are you not using our supplied cameras? What’s it deficient in? Thanks.
