Public bug reported:
Dell XPS 13 9350 (Lunar Lake, Intel Core Ultra 7 258V) running Ubuntu 26.04
with linux-image-oem-26.04 (7.0.0-1005-oem).
The built-in camera (OV02C10 via Intel IPU7) does not recover after
suspend/resume because int3472-discrete does not support the GPIO type 0x02
(handshake) pin used on Lunar Lake platforms with the Lattice USB-IO bridge.
dmesg shows:
int3472-discrete INT3472:00: GPIO type 0x02 unknown; the sensor may not work
gpio_usbio.usbio-gpio usbio.usbio-gpio.0: [Firmware Bug]: GPIO 4 is not in
FW pins bitmap
