![]() I'm not yet sure if we actually need that, or if we can get the images directly from the CSI-2 interface. There's a bit about all of that here (Section 3.4), but not really much to go on.Īs to drivers: There's currently some work upstream for the ISP device, it's currently in staging for 4.21. This is also a PCI device ( 8086:1919), and if I understand that correctly, independent of the CSI-2 interface. According to the kernel, those are TPS68470, which is a "Power Management IC (PMIC) with flash LED driver and ref clock generation for compact camera module", so that would fit in.Īlso there's the matter of the ISP (Image Signal Processor). Then there are the INT3472 devices, which are defined in the ACPI directly next to each camera sensor. This device is shared by all cameras (on KabyLake it can handle 4 of them parallel, on SkyLake 2 or 3, AFAIK depending on the configuration). The I2C interface is for stuff like setting the exposure etc., the actual images are provided via a MIPI CSI-2 (Camera Serial Interface) connection handled by a PCI device (with ID 8086:9d32). This is in fact the actual camera sensor, but it doesn't directly provide the images. Here's a rough overview: OV5693 is a camera sensor with an I2C interface. I've had a look at this over the past couple days and I still don't quite understand things as good as I'd like to get started. Yeah, unfortunately it won't be that easy.
