This is unfortunately a diverges from API available on thermal core. Can
you please add first on thermal core then, use it in of thermal?

I don't want to have callbacks available only via of thermal. If we
allow it, OF thermal becomes a separate API.
What ever happened to this effort?

Patch 12 and 13 look to accomplish something similar, yet they do what
Eduardo suggested. I was testing that series at my previous job, but
unfortunately (for the fate of this series) I left that employer before
I could finish reviewing and testing it. Perhaps Caesar can resurrect
and test it?

@Brian
Yes, I can

Sure, I can.

I see the Sascha's newest thermal patches in patchwork.
The following patches are still needed, right?

6446191 New          [06/16] thermal: inline only once used function
6446111 New          [07/16] thermal: streamline get_trend callbacks
6445871 New          [08/16] thermal: Allow sensor ops to fail with -ENOSYS
6445861 New [09/16] thermal: of: always set sensor related callbacks 6446221 New [10/16] thermal: Make struct thermal_zone_device_ops const 6446201 New [11/16] thermal: bang-bang governor: act on lower trip boundary 6445891 New [12/16] thermal: thermal: Add support for hardware-tracked trip points 6445911 New [13/16] thermal: of: implement .set_trips for device tree thermal zones

@Sascha, Eduardo
Can you share your discussion content for the above patches as remembered?

Thanks,

-Caesar
