The Arch wiki has some recordings of that. Most likely got fixed in
newer BIOSs to the BMI0XXX coding.

Based on the BIOS code from the OrangePi Neo the default value was
10EC5280 which got commented out and replaced by BMI0260. For BIOS v1.19
however OrangePi will use BOSC0260. I might provide a new DSDT dump as
soon as I get the newer BIOS from the vendor.
