From: https://wiki.ubuntu.com/Dell/XPS/XPS-13-7390-2-in-1

Intel Icelake integrated the IPU 4th Generation Gen IPU with on-die MIPI interface, which is not supported by Linux.

The current linux mainline 5.3 supports only Intel Image Processing Unit 3, tested on Kaby Lake platforms (U/Y processor lines). Since the IPU4 contains both scalar processor and vector processors, the lowest layer of the software stack is the firmware that runs on those cores. The IPU4 is a single PCI device but logically it is comprised of two independent systems: the input system (ISYS) and the processing system (PSYS). As such, each has its own driver.

The Linux camera stack is heavily reusing Android and keeps IPU FW, Kernel drivers, libiacss, and advanced 3A libraries exactly same as Android. An alternate Linux camera HAL has been introduced into the stack to provide a unique interface for upper-layer software. Specific in Yocto Linux, GStreamer is required as the multimedia framework where a camera source plugin for IPU4 will be needed.

Re: Dell XPS13-7390: integrated camera not detected

There might not yet be a driver for the camera.
However you may nevertheless provide some info like the output of

lspci
lsusb
dmesg

---

macro_rules! yolo { { $($tokens:tt)* } => { unsafe { $($tokens)* } }; }

Re: Dell XPS13-7390: integrated camera not detected

Seems that way indeed. I added output of lspci and lsusb to the original post. Switched back to zen kernel (5.4.3) to see if it would output any dev/video*, but it doesn't. I'll stick with 5.3 kernel for now, because there is a wifi issue with 5.4 kernel & iwlwifi.
