Hi all. Looking at my dmesg I’ve noticed issue with TPS68470 and OV5670 camera. It seem that the OS is unable to manage the TPS regulator and show me “int3472-tps68470 i2c-INT3472:05: error -ENODEV: No board-data found for this model” then the problem with TPS has repercussion on rear Omni Vision OV5670 camera module that show me that instead of use correct regulator, is using a “dummy one”: ov5670 i2c-INT3479:00: supply dvdd not found, using dummy regulator and same for dovdd
I’m on an HP Elite x2 1012 G2 with a Kaby Lake i5-7200u cpu and with the last bios version released from Hp installed. I’ve read that the problem is probably related to an incomplete AML for Bios firmware and then an incorrect DSDT that can’t be correctly interpretated by OS. Then the kernel workaround, in this case, is the use of a “dummy regulator” to move forward.
Also the dmsg output “ACPI BIOS Error (bug): AE_AML_PACKAGE_LIMIT, Index (0x000000005) is beyond end of object (length 0x5) (20250807/exoparg2-393)”seems to go in this direction.
Another things that I’ve noticed is a dmsg output of SElinux “SELinux: Permission firmware_load in class system not defined in policy”
I’m not really skilled with this kind of issue and I’m request to you if someone else have this kind of issue and how approached it.
Thank you
