Pull power management fixes from Rafael Wysocki: "These remove a stale DT entry left behind after recent removal of a cpufreq driver without users, fix up error handling in the imx6q cpufreq driver, fix two issues in the cpufreq documentation, and update the ARM cpufreq driver. Specifics: - Drop stale DT binding for the arm_big_little_dt driver removed recently (Sudeep Holla). - Fix up error handling in the imx6q cpufreq driver to make it report voltage scaling failures (Anson Huang). - Fix two issues in the cpufreq documentation (Viresh Kumar, Zhao Wei Liew). - Fix ARM cpuidle driver initialization regression from the 4.19 time frame and rework the driver registration part of it to simplify code (Ulf Hansson)" * tag 'pm-4.20-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ARM: cpuidle: Convert to use cpuidle_register|unregister() ARM: cpuidle: Don't register the driver when back-end init returns -ENXIO dt-bindings: cpufreq: remove stale arm_big_little_dt entry Documentation: cpufreq: Correct a typo cpufreq: imx6q: add return value check for voltage scale Documentation: cpu-freq: Frequencies aren't always sorted

This will give a fine grained information about all the CPU frequency
transitions. The cat output here is a two dimensional matrix, where an entry
<i,j> (row i, column j) represents the count of number of transitions from
-Freq_i to Freq_j. Freq_i is in descending order with increasing rows and
-Freq_j is in descending order with increasing columns. The output here also

+Freq_i to Freq_j. Freq_i rows and Freq_j columns follow the sorting order in
+which the driver has provided the frequency table initially to the cpufreq core
+and so can be sorted (ascending or descending) or unsorted. The output here
+also contains the actual freq values for each row and column for better
+readability.
If the transition table is bigger than PAGE_SIZE, reading this will
return an -EFBIG error.
