[PATCH] iio: adis16201: Correct inclinometer channel resolution
Posted by Gabriel Shahrouzi 7 months, 3 weeks ago 
The inclinometer channels were previously defined with 14 realbits.
However, the ADIS16201 datasheet states the resolution for these output
channels is 12 bits (Page 14, text description; Page 15, table 7).

Correct the realbits value to 12 to accurately reflect the hardware.

If you post a new version, always add the version number.

Anyhow, I was just asking for the fixes tag, but this is fine.

Applied to the fixes-togreg branch of iio.git

Thanks,

Jonathan

Ah, that makes sense - thanks for the clarification. I was debating
whether to just send the Fixes tag or resend the full patch, and
figured the full patch might make it easier to apply.

Should I have included the reviewed-by tag on the latest patch sent in
this thread since there were no changes to the code?

Yes, but that was all a mix up anyway so don't worry about it.
I have the tag anyway.

Not sure I had given a review tag for this.
Hard to find the previous versrion because it doesn't seem to contain adis16201
in the subject name :/
Anyway, good thing the fix should be added to IIO now.

Marcelo

Ah it's probably because I resent the patch in the same thread.
