[Rafael J. Wysocki]

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-4.20-rc3

with top-most commit 97dc6c03c1b0a9af7aa26da7b0b266a762451f5f

 Merge branch 'pm-cpuidle'

on top of commit 651022382c7f8da46cb4872a545ee1da6d097d2a

 Linux 4.20-rc1

to receive power management updates for 4.20-rc3.

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).

Thanks!
