Kernel 6.0, ov01a10 cannot find sensor anymore

[madsl]

Dell XPS 9320

System was working with 5.18 kernel, but after updating kernel to 6.0 and update to newest git on ipu6-drivers and ivsc-driver today, ov01a10 cannot find the sensor anymore. I've applied IOMMU-passthrough-for-intel-ipu.diff and int3472-support-independent-clock-and-LED-gpios-5.17 to the kernel, but it made no difference (maybe because the sensor is not an OV01A1S?)

Tried both with power_ctrl_logic enabled and disabled in the ipu6-drivers build, but maybe that module cannot be loaded at the same time as intel_skl_int3472* ?

@madsl Could you try dmesg | grep -i vsc? if no output, this PR may resolve it: https://github.com/intel/ipu6-drivers/pull/50

[madsl]

You're right, I get no output. I'll try the new instructions.

[madsl]

You're correct, it works when merging with ivsc-driver.
