Subject: [PATCH 1/1] Add 10EC5280 to bmi160_i2c ACPI IDs to allow binding on some devices
Date: Fri,  2 Feb 2024 18:30:41 +0100	[thread overview]
Message-ID: <20240202173040.26806-2-jesusmgh@gmail.com> (raw)

"10EC5280" is used by several manufacturers like Lenovo, GPD, or AYA (and 
probably others) in their ACPI table as the ID for the bmi160 IMU. This 
means the bmi160_i2c driver won't bind to it, and the IMU is unavailable 
to the user. Manufacturers have been approached on several occasions to 
try getting a BIOS with a fixed ID, mostly without actual positive 
results, and since affected devices are already a few years old, this is 
not expected to change. This patch enables using the bmi160_i2c driver for 
the bmi160 IMU on these devices.

A device-specific transformation matrix can then be provided in a second
step through udev hwdb.

This has been discussed before in 2021, see here:
https://lore.kernel.org/lkml/CACAwPwYQHRcrabw9=0tvenPzAcwwW1pTaR6a+AEWBF9Hqf_wXQ@mail.gmail.com/

Lenovo, as an example of a big manufacturer, is also using this ID:

At least some discussions with GPD took place on the GPD server Discord,
for which I can provide proof on demand via screenshot (if not accessible
directly).

I have read the patch submission instructions and followed them to the
best of my knowledge. Still, this is my first kernel patch submission,
so I'd be glad if you could please point out any mistakes. Thank you!
