Hi,
It's typical for embedded devices to use LM90-compatible sensor for
monitoring of CPU core and skin temperatures. The sensor is often
used by thermal zone that performs passive cooling and emergency
shutdown on overheat, hence it's more optimal to use interrupt for
a faster notification about temperature changes. Thermal framework
provides set_trips() callback for programming of temperature trips,
let's support it by HWMON.
Changelog:
v2: - Reworked set_trips() by making it generic. Now callback invokes
the min/max temperature write method directly, instead of using
additional new hwmon callback. This was suggested by Guenter Roeck.
- Added new patch that fixes integer overflows in the LM90 driver.
The fixes are necessary for supporting set_trips().

hwmon: (lm90) Prevent integer overflow of temperature calculations
hwmon: Support set_trips() of thermal device ops
