[PATCH v1 00/18] Thermal: Part 1 - Introduce new structs and registration

[AngeloGioacchino Del Regno]

This series is a preparation for a bigger cleanup that will be split in
three parts in order to avoid immutable branches on multiple subsystems,
as in other parts of this series there will be changes in:
- drivers/acpi
- drivers/platform/x86
- drivers/power/supply
- drivers/net/wireless
- drivers/net/ethernet

This is the first part which adds new structures and starts reorganizing
struct members around, plus, this migrates all of the thermal drivers
found in drivers/thermal/ to the new thermal_zone_device_register()
function, and advertises that the old registration functions are
deprecated and will be removed.

The reorganization is supposed to be complete (or mostly) but...
 - struct thermal_zone_platform_params has a temporary name:
   this is done in order to avoid compile time failures for
   the drivers outside of drivers/thermal before migrating
   them to thermal_zone_device_params/thermal_zone_device_register();
 - struct thermal_zone_params temporarily has two duplicated members,
   governor_name and no_hwmon;

Part 2 of this topic will migrate all drivers that are external to
drivers/thermal to thermal_zone_device_register(); I will send that
part only after part 1 is confirmed to be acceptable, as otherwise
I'd be spamming people for no reason :-)

After all drivers will be migrated to thermal_zone_device_register(),
we won't have to care about changing anything outside of drivers/thermal
to finish this set of cleanups/changes (and no immutable branches needed)
and this means that...
Part 3 of this topic will contain the following changes:
 - thermal_zone_device_register_with_trips() will be removed
 - thermal_tripless_zone_device_register() will be removed
 - thermal_zone_params will be renamed to thermal_governor_ipa_params
   - governor_name, no_hwmon members will be removed
 - thermal_zone_platform_params will be renamed to thermal_zone_params
 - Removal of the THERMAL_NAME_LENGTH limitation for `type`

More scheduled changes, which should end up in part 3 (at least that's
my intention), or eventually entirely after this cleanup topic, include:
 - Introduction of Thermal Zone names
 - Disambiguation of TZ name and type
 - Addition of `thermal-zones`, `thermal-zone-names` parsing for
   devicetrees

... Summarizing ...

Part 1:
 - Reorganize structures (some temporary names/leftovers)
 - New registration function, deprecation of old ones
 - Migration of drivers/thermal drivers to new registration

Part 2:
 - Migration of drivers in other subsystems to new thermal registration

Part 3:
 - Remove the two leftovers in thermal.h
 - Rename structures with proper, final names
 - Everything else, anyway.


Cheers,
Angelo
