Hello,
I am working on the IRS1125 Camera Sensor Driver Integration to Jetson Nano platform.
Note: IRS1125 Driver Source code borrowed it from Raspberry PI Kernel Source.
We have modified the IRS1125 driver and created separate “dtsi” files for the IRS1125 device ( Included in tegra210-porg-p3448-common.dtsi file ) to support with the Jetson Nano platform.
Attached the IRS1125 and common dtsi zip files for reference.

(16.7 KB)
With the above changes, the platform is capable to call the probe function of the IRS1125 driver.
The “driver insmod” process throws a segmentation fault. ( Logs are captured in the text file Jetson-IRS1125-logs.txt )

Our plan is to use the IRS1125 device under the standard V4L2 driver.
Could you please help us to understand and fix this issue?
Thanks in advance !
