Subject: [PATCH net-next 00/12] mlxsw: hwmon and thermal extensions

Vadim says:

This patchset contains various improvements to hwmon and thermal code in
mlxsw. The most significant improvement is the ability to read modules'
temperature attributes (input, fault, critical and emergency thresholds)
as well as fans' fault indication. These new attributes will improve the
ability to monitor the system.

Patches #1-#4 add the necessary device registers and APIs to read
modules' temperature attributes and fans' fault indication.

Patches #5-#8 perform small improvements in hwmon and thermal code such
as using a more indicative name for cooling devices.

Patch #9 exposes fans' fault indication via hwmon.

Patch #10 exposes modules' temperature attributes via hwmon.

Patch #11 adds an hwmon label to modules' temperature sensor. This helps
to parse the output of utilities such as "sensors".

Patch #12 allows to bind an external cooling device ("mlxreg-fan") to
mlxsw thermal zone. This will allow the mlxsw thermal zone to change the
cooling level of cooling devices not programmed via switch registers.

Vadim Pasternak (12):
  mlxsw: spectrum: Move QSFP EEPROM definitions to common location
  mlxsw: reg: Add Management Temperature Bulk Register
  mlxsw: reg: Add Fan Out of Range Event Register
  mlxsw: core: Add API for QSFP module temperature thresholds reading
  mlxsw: core: Set different thermal polling time based on bus frequency
  mlxsw: core: Modify thermal zone definition
  mlxsw: core: Replace thermal temperature trips with defines
  mlxsw: core: Rename cooling device
  mlxsw: core: Extend hwmon interface with fan fault attribute
  mlxsw: core: Extend hwmon interface with QSFP module temperature
  mlxsw: core: Add QSFP module temperature label attribute to hwmon
  mlxsw: core: Allow thermal zone binding to an external cooling device
