Description

My Dell Latitude 9330 2-in-1 uses an ipu6 webcam.
I'm running archlinux with the distro kernel (6.18.4 as of today).
The camera works (with some additional AUR package)
`[ 5.124701] intel-ipu6 0000:00:05.0: enabling device (0000 -> 0002)
[ 15.898642] intel-ipu6 0000:00:05.0: Found supported sensor OVTI02C1:00
[ 15.898789] intel-ipu6 0000:00:05.0: Connected 1 cameras
[ 15.901818] intel-ipu6 0000:00:05.0: IPU6-v3[465d] hardware version 5

[ 16.075375] intel_ipu6_psys.psys intel_ipu6.psys.40: psys probe minor: 0
`

but at startup I get these warnings:

`[ 4.896213] int3472-discrete INT3472:01: INT3472 seems to have no dependents.
[ 4.902828] int3472-discrete INT3472:06: cannot find GPIO chip INTC1096:00, deferring
....
[ 5.342478] int3472-discrete INT3472:06: cannot find GPIO chip INTC1096:00, deferring
[ 5.397084] int3472-discrete INT3472:06: GPIO type 0x02 unknown; the sensor may not work
`

Moreover if the camera is enabled in the BIOS, the boot process is waiting 10s while mounting /boot and /efi partitions.

Research direction

Reproduce the startup on the Dell Latitude 9330 2-in-1 with the camera enabled, using the reported INT3472 and intel-ipu6 log entries as the starting point. Trace the GPIO and dependent-device warnings, then verify that the warnings and the 10-second /boot and /efi mount delay are gone without breaking camera operation.
