Subject: [PATCH 0/3] Add temperature notification support

UFS3.0 allows using the ufs device as a temperature sensor. The purpose
of this optional feature is to provide notification to the host of the
UFS device case temperature. It allows reading of a rough estimate
(+-10 degrees centigrade) of the current case temperature, and setting a
lower and upper temperature bounds, in which the device will trigger an
applicable exception event.

A previous attempt [1] tried a comprehensive approach.  Still, it was
unsuccessful. Here is a more modest approach that introduces just the
bare minimum to support temperature notification.

Thanks,
Avri
