ov5640 isp porting on imx8mp evk

Hello NXP community,

I use imx8mp evk with yocto bsp version LF6.6.3_1.0.0 bsp version.

i have one ov5640 camera which i connect to mipi csi.

From dts file i came to know that this is ported via isi, since when i disable isi node in dts then it's not working. [correct me if my assumption is wrong].

now i wanted to port it via isp, tried adding isp node by disabling isi node but output shows -  no video capture device. Below are the changes i tried in imx8mp-evk.dts file.

&isi_0 {
status = "disabled";
 
cap_device {
status = "disabled";
};
 
m2m_device {
status = "disabled";
};
};
 
&isp_0 {
status = "okay"
};
 
also tried
&isp_0 {
status = "okay"
 
cap_device {
status = "okay";
};
 
m2m_device {
status = "okay";
};
 
Both changes didn't work.
 
 
So, Can you please let me know what changes to do for porting ov5640 via isp.
 
Thanks in Advance

current bsp doesn't support ov5640 via ISP, more work you need to do, you need add the ov5640 mipi driver in the vvcam and isp-imx, and build the ov5640 driver module for isp, not just change the isi to the isp, this is just the first steps, you can refer to the enclosed application note
