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
