It could have gone to drivers/iio/accel if it would use an iio  
interface, which would make more sense, you are right, but I 
simply  don't have the time to merge it in to iio.

It doesn't use an input interface either but I don't see a good  
place for an accelerometer that uses sysfs only.

It works well, is a relatively recent chip and a clean dirver. 
But  this is all I can provide.
As a person who works on the user-space interaction of those with  
desktops [1]: Urgh.

I already have 3 (probably 4) types of accelerometers to contend 
with,  I'm not fond of adding yet another type.

Is there any way to get this hardware working outside the SoCs 
it's  designed for (say, a device with I2C like a Raspberry Pi), 
so that a  kind soul could handle getting this using the right 
interfaces?
It works on basically any SoC and is in no way limited in this 
regard. Sure, userspace has to expicitely support it and I hear you. 
Using the iio interface would make more sense. I can only say I'd 
love to have the time to move this driver over. I'm very sorry.
How can we get the hardware for somebody to use on their own 
laptops/embedded boards to implement this driver?
It's connected over I2C. If the included documentation is not clear
please tell me what exacly. Thanks!
