Temperature should be reported in milli-degrees, not degrees. Fix
scale values to use the correct unit.
Fix round-up offset value for MPU6050 and add the values for
MPU6500 family (different from MPU6050).

Add support of temperature data in fifo for all chips.
Enable unification of scan elements for icm20602.
Add macros for generating scan elements with and without temp.

Hi.
This is combining several different things, but I can see that it
isn't easy to separate them out so I'll take it as is.
However, we need some information on how to backport this?
I'm guessing it won't be clean to do as the different parts
were added over time. Perhaps a fixes tag for now to the latest
change that affects this code, then look at backporting relevant
parts by hand.
Thanks,
Jonathan

Looks fine to me. I'll pick up once we've worked out what
we are doing with patch 1.
Remind me if I seem to have lost it.

Hi Jonathan,
any news about my 2nd patch ("[PATCH 2/2] iio: imu: inv_mpu6050: add fifo temperature data support") now that the 1st is included inside fixes-togreg branch?
The 1st one is still not yet available inside testing branch.
Should I resend it now or wait for testing to be in sync with fixes-togreg?
Thanks,
JB

Hi Jonathan,
just a reminder for not forgetting this patch now that the first is in fixes-togreg branch.

Looks fine to me. I'll pick up once we've worked out what
we are doing with patch 1.
Remind me if I seem to have lost it.
Thanks,
Jonathan

I have it flagged in my email so in theory at least I will grab it
without a resend. I think I'll do a pull request for togreg later this

Hi Jonathan,
a kind reminder about this patch still waiting. Now testing branch is ready for it to be applied.
I've got a good number of other patches just waiting for this one to be accepted before sending.
Thanks,
JB

I have it flagged in my email so in theory at least I will grab it
without a resend. I think I'll do a pull request for togreg later this
week and after that I should be fine applying this.
Things got a bit slowed down for the holidays :) Too easy to put
things off to tomorrow!
