drivers: thermal: add check when unregistering cpu cooling

2013-09-03T13:10:34+00:00

This patch avoids NULL pointer accesses while unregistering
cpu cooling devices, in case a NULL pointer is received.

thermal: thermal_core: allow binding with limits on bind_params

2013-09-03T13:10:24+00:00

When registering a thermal zone device using platform information
via bind_params, the thermal framework will always perform the
cdev binding using the lowest and highest limits (THERMAL_NO_LIMIT).

This patch changes the data structures so that it is possible
to inform what are the desired limits for each trip point
inside a bind_param. The way the binding is performed is also
changed so that it uses the new data structure.

drivers: thermal: make usage of CONFIG_THERMAL_HWMON optional

2013-09-03T13:10:11+00:00

When registering a new thermal_device, the thermal framework
will always add a hwmon sysfs interface.

This patch adds a flag to make this behavior optional. Now
when registering a new thermal device, the caller can
optionally inform if hwmon interface is desirable. This can
be done by means of passing a thermal_zone_params.no_hwmon == true.

In order to keep same behavior as of today, all current
calls will by default create the hwmon interface.

drivers: thermal: parent virtual hwmon with thermal zone

2013-09-03T13:10:10+00:00

When  creating virtual hwmon devices based out of thermal
zone devices, the virtual devices won't have parents.

This patch changes the code so that the parent of virtual
hwmon devices is the thermal zone device that they are
based of.

thermal: hwmon: move hwmon support to single file

2013-09-03T13:09:12+00:00

In order to improve code organization, this patch
moves the hwmon sysfs support to a file named
thermal_hwmon. This helps to add extra support
for hwmon without scrambling the code.

In order to do this move, the hwmon list head is now
using its own locking. Before, the list used
the global thermal locking. Also, some minor changes
in the code were required, as recommended by checkpatch.pl.

thermal: exynos: Clean up non-DT remnants

2013-08-29T13:37:31+00:00

Commit 1cd1ecb6 ("thermal: exynos: Remove non DT based support")
cleaned up some non-DT code. However, there were few more things
needed for complete cleanup to make this driver DT only.
