Specifics: - Fix a regression in leds-gpio introduced by a recent commit that inadvertently changed the name of one of the properties used by the driver (Fabio Estevam). - Fix a regression in the ACPI backlight driver introduced by a recent fix that missed one special case that had to be taken into account (Aaron Lu). - Drop the level of some new kernel messages from the ACPI core introduced by a recent commit to KERN_DEBUG which they should have used from the start and drop some other unuseful KERN_ERR messages printed by ACPI (Rafael J Wysocki). - Revert an incorrect commit modifying the cpupower tool (Prarit Bhargava). - Fix two regressions introduced by recent commits in the OPP library and clean up some existing minor issues in that code (Viresh Kumar). - Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout the tree (or drop it where that can be done) in order to make it possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki, Ulf Hansson, Ludovic Desroches). There will be one more "CONFIG_PM_RUNTIME removal" batch after this one, because some new uses of it have been introduced during the current merge window, but that should be sufficient to finally get rid of it. - Make the ACPI EC driver more robust against race conditions related to GPE handler installation failures (Lv Zheng). - Prevent the ACPI device PM core code from attempting to disable GPEs that it has not enabled which confuses ACPICA and makes it report errors unnecessarily (Rafael J Wysocki). - Add a "force" command line switch to the intel_pstate driver to make it possible to override the blacklisting of some systems in that driver if needed (Ethan Zhao). - Improve intel_pstate code documentation and add a MAINTAINERS entry for it (Kristen Carlson Accardi). - Make the ACPI fan driver create cooling device interfaces witn names that reflect the IDs of the ACPI device objects they are associated with, except for "generic" ACPI fans (PNP ID "PNP0C0B"). That's necessary for user space thermal management tools to be able to connect the fans with the parts of the system they are supposed to be cooling properly.

All remaining board files that were written in C are dropped, and the ancient at91x40 sub-platform (based on an MMU-less ARM7) is removed altogether. Cleaning up the last pieces was great fun, so I took the time to do some of the coding myself and removed several hundred code lines that ended up unused after the board files were done. There are still a couple of AT91 specific device drivers that are not converted to DT (CF, USB-OTG) and currently not working, and the platform itself is not "multiplatform"-enabled, but both issues are going to be taken care of in the 3.20 cycle.

Probably most SoC have a watchdog, and some of them register it also as a restart handler. But if a SoC specifies a dedicated reboot capability using this syscon driver, this is usually the preferred reboot method. Hence, raise the priority of this driver to 192.
