Thanks. Agreed: the Intel INT3472 drivers are present and loaded (intel_skl_int3472_discrete, intel_skl_int3472_common, intel_skl_int3472_tps68470). The issue appears to be incomplete/incorrect ACPI INT3472 GPIO/power sequencing for this Dell model/sensor combination: the IPU6 stack loads, but no /dev/media* or /dev/video* nodes are created. This matches the kernel log warning: “INT3472: GPIO type 0x02 unknown; the sensor may not work”. Please advise what additional logs would help (e.g. full dmesg, ACPI tables, acpidump, lspci -nnk, ls /sys/bus/acpi/devices/INT3472:*, etc.).
