Dell Latitude 7440/0982JK with OV02C10 not working

[mana-z]

Hi!

My 6.12.1-arch1-1 is not seeing the webcam (my dual-booted windows say it's OV02C10).

Here's output of my sudo dmesg|grep -E "ipu|vsc":

Obviously no /dev/video* is present and nothing is available with cam -l.

Trying to fix this, I already compiled in a bunch of patches to my kernel:
https://gist.github.com/xTeixeira/36efa073da784609f23dee3d2d017671
https://lore.kernel.org/all/[email protected]/
https://lore.kernel.org/all/[email protected]/
https://lore.kernel.org/all/[email protected]/
https://bugzilla-attachments.redhat.com/attachment.cgi?id=2059082
plus the three from /patch/v6.12 and DKMS modules from this repo.

The SPI fix from bugzilla did change the error from -22 to -110.

lspci does show Multimedia controller: Intel Corporation Device a75d (rev 01)

EDIT: retried today with full in-tree method to same result. I haven't removed any of the patches.
