Pull thermal updates from Zhang Rui:

 - Implement generic devfreq cooling mechanism through frequency
   reduction for devices using devfreq.  From Ørjan Eide and Javi
   Merino.

 - Introduce OMAP3 support on TI SoC thermal driver.  From Pavel Mack
   and Eduardo Valentin.

 - A bounch of small fixes on devfreq_cooling, Exynos, IMX, Armada, and
   Rockchip thermal drivers.

remove abs64()

2015-11-09T23:11:24+00:00

Switch everything to the new and more capable implementation of abs().
Mainly to give the new abs() a bit of a workout.

thermal: exynos: Directly return 0 instead of using local ret variable

2015-11-04T19:10:39+00:00

The 'ret' variable in exynos5440_tmu_initialize() is initialized to 0
and returned as is. Replace it with direct return statement. This also
fixes coccinelle warning:
drivers/thermal/samsung/exynos_tmu.c:611:5-8: Unneeded variable: "ret". Return "0" on line 654

thermal: exynos: Use IS_ERR() because regulator cannot be NULL

2015-11-04T19:09:39+00:00

The NULL check in probe's error path is not needed because in that time
the regulator cannot be NULL (regulator_get() returns valid pointer or
ERR_PTR).

thermal: exynos: Fix first temperature read after registering sensor

2015-11-04T19:08:30+00:00

Thermal core could not read the temperature after registering the
thermal sensor with thermal_zone_of_sensor_register() because the driver
was not yet initialized.

The call trace looked like:
    exynos_tmu_probe()
        thermal_zone_of_sensor_register()
            of_thermal_set_mode()
                thermal_zone_device_update()
                    exynos_get_temp()
                        if (!data->tmu_read) return -EINVAL;
        exynos_map_dt_data()
            data->tmu_read = ...

This produced an error in dmesg:
thermal thermal_zone0: failed to read out thermal zone (-22)

Register the thermal_zone_device later, after parsing Device Tree and
enabling necessary clocks, but before calling exynos_tmu_initialize()
which uses the registered thermal_zone_device.

thermal: exynos: Fix unbalanced regulator disable on probe failure

2015-11-04T19:07:51+00:00

During probe if the regulator could not be enabled, the error exit path
would still disable it. This could lead to unbalanced counter of
regulator enable/disable.

The patch moves code for getting and enabling the regulator from
exynos_map_dt_data() to probe function because it is really not a part
of getting Device Tree properties.
