[PATCH v2 0/2] Support temperature trips by HWMON core and LM90 driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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().

Dmitry Osipenko (2):
  hwmon: (lm90) Prevent integer overflow of temperature calculations
  hwmon: Support set_trips() of thermal device ops
