This driver supports both Armada 370 and Armada XP SoC thermal management controllers. Armada 370 has a register to check a valid temperature, whereas Armada XP does not. Each has a different initialization (i.e. calibration) function. The temperature conversion formula is the same for both. The controller present in each SoC have a very similar feature set, so it corresponds to have one driver to support both of them. Although this driver may present similarities to Dove and Kirkwood thermal driver, the exact differences and coincidences are not fully known. For this reason, support is given through a separate driver. Signed-off-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>

tristate "Generic Thermal sysfs driver"
|
|
help
|
|
Generic Thermal Sysfs driver offers a generic mechanism for
|
|
thermal management. Usually it's made up of one or more thermal
|
|
zone and cooling device.
|
|
Each thermal zone contains its own temperature, trip points,
|
|
cooling devices.
|
|
All platforms with ACPI thermal support can use this driver.
|
|
If you want this support, you should say Y or M here.

This implements the generic cpu cooling mechanism through frequency

reduction, cpu hotplug and any other ways of reducing temperature. An

ACPI version of this already exists(drivers/acpi/processor_thermal.c).

This will be useful for platforms using the generic thermal interface

and not the ACPI interface.
