Jetpack6.2 gmsl Module Device Tree issue

[lzjie]

Hi,
I am trying to support gmsl camera use max96712,max9295 and imx390,my device is Agx Orin dev kit 64GB,and using jetpack6.2.However,when I refer to Jetson Virtual Channel with GMSL Camera Framework — NVIDIA Jetson Linux Developer Guide. I can not find “gmsl-link” node in “tegra234-camera-imx390-a00.dtsi”.So I want to know if the tutorial has not been updated?
And can you offer a reference dts file use max96712,max9295 and imx390.Thanks.

Looks like JP6 remove it.
You can check the nv_imx390.c to confirm it.

Thanks

Below change remove it.
Looks like enable WDR mode and remove virtual channel.
You can still follow the document for virtual channel use case.

overlay: t23x: enable IMX390 WDR mode

Enable WDR(wide dynamic range) mode for IMX390.
1 Add WDR mode table to IMX390 overlay.
2 Support only link A in desrializer
  (only one sensor is supported for now).

Add tegra234-p3737-camera-imx390-addr-0x21-overlay.dtbo
for IMX390 sensor with i2c address 0x21.
