You're right. I should've looked more closely. oversampling is there and
seems to

Hey Harinath,
I think it'd be great to have the "power_mode" iio ABI interface
for mma8452 too, and I just found an old patch pf mine for this.

This adds the power_mode sysfs interface to the device as documented in
sysfs-bus-iio.

-next tree because of cleanup changes in the meantime. Also, the patches are
slightly more cleaned up (adding the DT bindings document in the right patch).
Here we go:

This adds a struct mma_chip_info to hold data that will remain specific to
the chip in use. It is provided during probe() and linked in
struct of_device_id.
Also this suggests that the driver is called "mma8452" and now handles the
MMA8452Q device, but is not limited to it.

These are 4 of probably many examples of what could be changed if the proposed
sign_extend8, 16 and 64 are added to bitops.h, now as real patches.
Again, keep in mind, only take them if "PATCH v2 add sign_exted8, 16 and 64"
is included first.

This adds helper functions for sign-extending signed values of any lower

In other words: Is a RISING event fired on an absolute growing value in

Or is a RISING event fir
