Maybe we can grep for the added BOSC IDs in the kernel and see if it gives any contacts / clues whom to contact, but I'm not insisting you to go this way, only if you want to. > In the meantime, I can reorder the patches to add the triggers and > attributes first and leave the BMI260 support / ACPI ID additions at the > end. > > I'll include the BMI0160 ID (and DSDT) in the patch adding the initial > support, since we know that one exists in the wild, and hold on adding > BOSC0260 until there's a way to move forward on it.

Since ACPI has the different resource types for these busses it's usually okay to have the same ID in both, but there is no special requirement for following or not following that. And taking a history of fake ACPI IDs in the past, I would go defensive way as you put it here, i.e. no ID should be added until we have a proof of them being used in the real products. -- With Best Regards, Andy Shevchenko
