Pull thermal management update from Zhang Rui: "Summary: - of-thermal extension to allow drivers to register and use its functionality in a better way, without exploiting thermal core. From Lukasz Majewski. - Fix a bug in intel_soc_dts_thermal driver which calls a sleep function in interrupt handler. From Maurice Petallo. - add a thermal UAPI header file for exporting the thermal generic netlink information to user-space. From Florian Fainelli. - First round of refactoring in Exynos driver. Bartlomiej and Lukasz are attempting to make it lean and easier to understand. - New thermal driver for Rockchip (rk3288), with support for DT thermal. From Caesar Wang. - New thermal driver for Nvidia, Tegra124 SOCTHERM driver, with support for DT thermal. From Mikko Perttunen. - New cooling device, based on common clock framework. From Eduardo Valentin. - a couple of small fixes in thermal core framework.

Pull driver core update from Greg KH: "Here's the set of driver core patches for 3.19-rc1. They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes.

drivers: thermal: Remove ARCH_HAS_BANDGAP dependency for samsung

2014-12-10T15:06:18Z

As samsung thermal support is enabled only for ARCH_EXYNOS, there is no need to select ARCH_HAS_BANDGAP from the arch-specific code. Removing this dependency will also allow the driver to be enabled on 64-bit SoCs.

thermal: exynos: pass cpu_present_mask to cpufreq_cooling_register()

2014-12-08T16:08:54Z

cpufreq_cooling_register() expects mask of all the CPUs where frequency constraint is applicable. This platform has more than one CPU to which these constraints will apply and so passing mask of only CPU0 wouldn't be sufficient. Also, this platform has a single cluster of CPUs and the constraint applies to all CPUs. If CPU0 is hoplugged out then we may face strange BUGs as cpu_cooling framework isn't aware of any siblings sharing clock line. Fix it by passing cpu_present_mask to cpufreq_cooling_register().

thermal: cpu_cooling: check for the readiness of cpufreq layer

2014-12-08T16:08:53Z

In this patch, the cpu_cooling code checks for the usability of cpufreq layer before proceeding with the CPU cooling device registration. The main reason is: CPU cooling device is not usable if cpufreq cannot switch frequencies. Similar checks are spread in thermal drivers. Thus, the advantage now is to have the check in a single place: cpu cooling device registration. For this reason, this patch also updates the existing drivers that depend on CPU cooling to simply propagate the error code of the cpu cooling registration call. Therefore, in case cpufreq is not ready, the thermal drivers will still return -EPROBE_DEFER, in an attempt to try again when cpufreq layer gets ready.

thermal: Exynos: Deletion of unnecessary checks before two function calls

2014-11-21T19:20:17Z

The functions cpufreq_cooling_unregister() and thermal_zone_device_unregister() test whether their argument is NULL and then return immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Eduardo Valentin

thermal: exynos: remove exynos_tmu_data.h include

2014-11-20T14:54:50Z

There is no longer need to share defines between exynos_tmu.c and exynos_tmu_data.c (as they are now only used by the former file) so move them accordingly. Then move externs for struct exynos_tmu_init_data instances to exynos_tmu.h and remove no longer needed exynos_tmu_data.h include. There should be no functional changes caused by this patch.
