Subject: [PATCH 00/31] thermal: reorganizing thermal core

Folks,

Here is a series of patches I am proposing to add to thermal core
with the intent to have a better code organization. It started
as an RFC for sysfs handling [1]. But now, on top of the sysfs
organization, I added a code split as well.

The only change in behavior is that now, thermal zones with empty
.type will not be allowed to be registered.

After this series, thermal core is split into the following files:
- thermal_sysfs.c: contains the functions handling the sysfs nodes
- thermal_helpers.c: groups functions that do not need to touch thermal
core internal data structures, such as internal lists, and list locks.
- thermal_core.c: functions to handle the lifecycle of the subsystem,
its governors, cooling devices, thermal zone devices, and their
interactions.

I don't expect any impact on userspace.

Please give your inputs.

BR,
