Subject: [PATCH net-next 0/9] mlxsw: Preparations for line cards support

Currently, mlxsw registers thermal zones as well as hwmon entries for
objects such as transceiver modules and gearboxes. In upcoming modular
systems, these objects are no longer found on the main board (i.e., slot
0), but on plug-able line cards. This patchset prepares mlxsw for such
systems in terms of hwmon, thermal and cable access support.

Patches #1-#3 gradually prepare mlxsw for transceiver modules access
support for line cards by splitting some of the internal structures and
some APIs.

Patches #4-#5 gradually prepare mlxsw for hwmon support for line cards
by splitting some of the internal structures and augmenting them with a
slot index.

Patches #6-#7 do the same for thermal zones.

Patch #8 selects cooling device for binding to a thermal zone by exact
name match to prevent binding to non-relevant devices.

Patch #9 replaces internal define for thermal zone name length with a
common define.

Vadim Pasternak (9):
  mlxsw: core: Extend interfaces for cable info access with slot
    argument
  mlxsw: core: Extend port module data structures for line cards
  mlxsw: core: Move port module events enablement to a separate function
  mlxsw: core_hwmon: Extend internal structures to support multi hwmon
    objects
  mlxsw: core_hwmon: Introduce slot parameter in hwmon interfaces
  mlxsw: core_thermal: Extend internal structures to support multi
    thermal areas
  mlxsw: core_thermal: Add line card id prefix to line card thermal zone
    name
  mlxsw: core_thermal: Use exact name of cooling devices for binding
  mlxsw: core_thermal: Use common define for thermal zone name length
