Hello,

auto focus doesn't defined in the dts file, should support in the ISP v4l2 API, you can refer to the document as below:

Hi @Bio_TICFSL ,

Thanks for the reply.

Those who want to integrate Auto focus with OV5640 on IMX8MM. Please follow below link for reference:

https://github.com/boundarydevices/linux/tree/boundary-imx_5.15.y/drivers/media/platform/mxc/capture

Change kernel version according to you BSP. By referring files preset in mentioned directory you can enable below functionalities:

Auto focus functionality

You need to have OV5640 module with VCM. Above driver implementation doesn't support continuous auto focus. User need to pass "v4l2-ctl -d /dev/video0 -c auto_focus_start=1" command each time to get focus.

Thanks,
