Merge branch 'cpufreq/arm/linux-next' of git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm
Pull cpufreq material for v5.6 from Viresh Kumar:
"This contains:
- Update to imx cpufreq driver to add support for i.MX8MP platform.
- Blacklists few NVIDIA SoCs from cpufreq-dt-platdev layer.
- Convertion of few platform drivers to use
devm_platform_ioremap_resource().
- Fixed refcount imbalance in few drivers."
