Better yet, would be to use the same interface the hdaps driver uses
so that userspace written for one accelerometer works with any hardware.
Having to cope with a dozen different drivers who export in different
places is just silly.
That would probably mean that there is a need for single interface. Making
all accelerometers
export to /sys/devices/platform/hdaps sounds wrong to me. It should be a
neutral place then.
There aren't that many accelerometers right now as far as I could tell by
googling.
There are hdaps, amc (something for MAC I think) and now mdps ;)
Only amc and mdps are 3D - hdaps is 2D, and also amc and mdps in theory
support
a free-fall interrupt instead of polling - I just couldn't get the interrupt
part to work yet.
I did make the interface as close as I could to hdaps - seem my later post
with a new patch.
