2016-11-23thermal: core: move trips attributes to tz->device.groupsEduardo Valentin
Finally, move the last thermal zone sysfs attributes to tz->device.groups: trips attributes. This requires adding a attribute_group to thermal_zone_device, creating it dynamically, and then setting all trips attributes in it. The trips attribute is then added to the tz->device.groups. As the removal of all attributes are handled by device core, the device remove calls are not needed anymore.

2016-11-23thermal: core: move passive attr to tz->device.groupsEduardo Valentin
This patch moves the passive attribute to tz->device.groups. Moving the passive attribute also requires a .is_visible() callback implementation for its attribute group.

2016-11-23thermal: core: use dev.groups to manage always present tz attributesEduardo Valentin
Thermal zones attributes are all being created using device_create_file(). This has the disadvantage of making the code complicated and sometimes we may miss the cleanup of them. This patch starts to move the thermal zone sysfs attributes to the dev.groups, so Linux device core manage them for us. For now, this patch only moves those attributes are always present regardless of thermal zone condition. This change has also the advantage of cleaning up the thermal zone parameters sysfs entries that are left unclean after device registration.

2016-11-23thermal: intel_pch_thermal: Support skylake PCH 100 series thermalOGAWA Hirofumi
This patch uses .driver_data and board_info[] to make per pci device behavior table (name and ops), instead of adding the code for each pci device in switch-case. This will make easier to add new pci device ids.

2016-10-27genetlink: mark families as __ro_after_initJohannes Berg
Now genl_register_family() is the only thing (other than the users themselves, perhaps, but I didn't find any doing that) writing to the family struct. In all families that I found, genl_register_family() is only called from __init functions (some indirectly, in which case I've add __init annotations to clarifly things), so all can actually be marked __ro_after_init. This protects the data structure from accidental corruption. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-10-27genetlink: statically initialize familiesJohannes Berg

2016-10-27genetlink: no longer support using static family IDsJohannes Berg
Static family IDs have never really been used, the only use case was the workaround I introduced for those users that assumed their family ID was also their multicast group ID. Additionally, because static family IDs would never be reserved by the generic netlink code, using a relatively low ID would only work for built-in families that can be registered immediately after generic netlink is started, which is basically only the control family (apart from the workaround code, which I also had to add code for so it would reserve those IDs) Thus, anything other than GENL_ID_GENERATE is flawed and luckily not used except in the cases I mentioned. Move those workarounds into a few lines of code, and then get rid of GENL_ID_GENERATE entirely, making it more robust. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S.

git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux Pull thermal managament updates from Zhang Rui: - Enhance thermal "userspace" governor to export the reason when a thermal event is triggered and delivered to user space. From Srinivas Pandruvada - Introduce a single TSENS thermal driver for the different versions of the TSENS IP that exist, on different qcom msm/apq SoCs'. Support for msm8916, msm8960, msm8974 and msm8996 families is also added. From Rajendra Nayak - Introduce hardware-tracked trip points support to the device tree thermal sensor framework. The framework supports an arbitrary number of trip points. Whenever the current temperature is changed, the trip points immediately below and above the current temperature are found, driver callback is invoked to program the hardware to get notified when either of the two trip points are triggered. Hardware-tracked trip points support for rockchip thermal driver is also added at the same time. From Sascha Hauer, Caesar Wang - Introduce a new thermal driver, which enables TMU (Thermal Monitor Unit) on QorIQ platform. From Jia Hongtao - Introduce a new thermal driver for Maxim MAX77620. From Laxman Dewangan - Introduce a new thermal driver for Intel platforms using WhiskeyCove PMIC. From Bin Gao - Add mt2701 chip support to MTK thermal driver.
