Subjecti.MX6 MIPI-CSI2 OV5640 Camera testing on Mainline Linux
Hi All,

I'm trying to verify MIPI-CSI2 OV5640 camera on i.MX6 platform with
Mainline Linux.

I've followed these[1] instructions to configure MC links and pads
based on the probing details from dmesg and trying to capture
ipu1_ic_prpenc capture (/dev/video1) but it's not working.

Can anyone help me to verify whether I configured all the details
properly if not please suggest.

I'm pasting full log here, so-that anyone can comment in line and dt
changes are at [2]
