What does this u32 describe? I wonder if we can introduce a generic
property instead of a vendor-specific one.

Describes a "noise rejection level"... zero is disabled, 1-2-3 are
min-med-high. That's what the hardware accepts.

Also, there's no "real" documentation on this, so it wasn't possible
to map it to any real measurement unit as well...
