Pull more power management updates from Rafael Wysocki:
"These are mostly ARM cpufreq driver updates, including one new
MediaTek driver that has just passed all of the reviews, with the
addition of a revert of a recent intel_pstate commit, some core
cpufreq changes and a DT-related update of the operating performance
points (OPP) support code.
Specifics:
- Add new cpufreq driver for the MediaTek MT6779 platform called
mediatek-hw along with corresponding DT bindings (Hector.Yuan).
- Add DCVS interrupt support to the qcom-cpufreq-hw driver (Thara
Gopinath).
- Make the qcom-cpufreq-hw driver set the dvfs_possible_from_any_cpu
policy flag (Taniya Das).
- Blocklist more Qualcomm platforms in cpufreq-dt-platdev (Bjorn
Andersson).
- Make the vexpress cpufreq driver set the CPUFREQ_IS_COOLING_DEV
flag (Viresh Kumar).
- Add new cpufreq driver callback to allow drivers to register with
the Energy Model in a consistent way and make several drivers use
it (Viresh Kumar).
- Change the remaining users of the .ready() cpufreq driver callback
to move the code from it elsewhere and drop it from the cpufreq
core (Viresh Kumar).
- Revert recent intel_pstate change adding HWP guaranteed performance
change notification support to it that led to problems, because the
notification in question is triggered prematurely on some systems
(Rafael Wysocki).
- Convert the OPP DT bindings to DT schema and clean them up while at
it (Rob Herring)"

=======================================
如何实现一个新的CPUFreq处理器驱动程序?
.resume - 一个指向per-policy恢复函数的指针,该函数在关中断且在调节器再一次开始前被
调用。
- .ready - 一个指向per-policy准备函数的指针,该函数在策略完全初始化之后被调用。
-
.attr - 一个指向NULL结尾的"struct freq_attr"列表的指针,该函数允许导出值到
sysfs。
