Pull power management fixes from Rafael Wysocki: "These fix two issues in the Operating Performance Points (OPP) framework, one cpufreq driver issue, one problem related to the tasks freezer and a few build-related issues in the cpupower utility. Specifics: - Fix tasks freezer deadlock in de_thread() that occurs if one of its sub-threads has been frozen already (Chanho Min). - Avoid registering a platform device by the ti-cpufreq driver on platforms that cannot use it (Dave Gerlach). - Fix a mistake in the ti-opp-supply operating performance points (OPP) driver that caused an incorrect reference voltage to be used and make it adjust the minimum voltage dynamically to avoid hangs or crashes in some cases (Keerthy). - Fix issues related to compiler flags in the cpupower utility and correct a linking problem in it by renaming a file with a duplicate name (Jiri Olsa, Konstantin Khlebnikov)" * tag 'pm-4.20-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: exec: make de_thread() freezable cpufreq: ti-cpufreq: Only register platform_device when supported opp: ti-opp-supply: Correct the supply in _get_optimal_vdd_voltage call opp: ti-opp-supply: Dynamically update u_volt_min tools cpupower: Override CFLAGS assignments tools cpupower debug: Allow to use outside build flags tools/power/cpupower: fix compilation with STATIC=true
