Thanks for doing this. Does the ADXL34 work now? Last time I
tried it, I didn't get any interrupts, but as I didn't really
care for the accelerometer I didn't dig deeper.

Add a space here and ...

here. Also, this should be accelerometer@53.

Please remove the spaces here.

Finally, please sort the nodes alphabetically and not just append them.

Yes, now it works. There was a problem with the interrupts as the gpio was
probed after i2c. I have done some patches to fix this but some else
did a better job
deferring the probe so now it work out of the box.
