Subject: [GIT PULL] More power management updates for v5.19-rc1
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-5.19-rc1-2
with top-most commit 9f9c1f6844bdacb4a011cc69e19b929997038f4f
Merge branch 'pm-sysoff'
on top of commit 09583dfed2cb9723da31601cb7080490c2e2e2d7
Merge tag 'pm-5.19-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
to receive more power management updates for 5.19-rc1.
These update the ARM cpufreq drivers and fix up the CPPC cpufreq
driver after recent changes, update the OPP code and PM documentation
and add power sequences support to the system reboot and power off
code.
Specifics:
- Add Tegra234 cpufreq support (Sumit Gupta).
- Clean up and enhance the Mediatek cpufreq driver (Wan Jiabing,
Rex-BC Chen, and Jia-Wei Chang).
- Fix up the CPPC cpufreq driver after recent changes (Zheng Bin,
Pierre Gondois).
- Minor update to dt-binding for Qcom's opp-v2-kryo-cpu (Yassine
Oudjana).
- Use list iterator only inside the list_for_each_entry loop (Xiaomeng
Tong, and Jakob Koschel).
- New APIs related to finding OPP based on interconnect bandwidth
(Krzysztof Kozlowski).
- Fix the missing of_node_put() in _bandwidth_supported() (Dan
Carpenter).
- Cleanups (Krzysztof Kozlowski, and Viresh Kumar).
- Add Out of Band mode description to the intel-speed-select utility
documentation (Srinivas Pandruvada).
- Add power sequences support to the system reboot and power off
code and make related platform-specific changes for multiple
platforms (Dmitry Osipenko, Geert Uytterhoeven).
Thanks!
