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)"

Convert Samsung Exynos PPMU bindings to DT schema format using
json-schema. The example is quite different due to the nature of
dtschema examples parsing (no overriding via-label allowed).
New bindings contain copied description from previous bindings document,
therefore the license is set as GPL-2.0-only.

Convert the OPP v1 and v2 bindings to DT schema format. As the OPPv2 binding
can be extended by vendors, we need to split the common part out from the
"operating-points-v2" conforming compatible.

The ACTMON watches activity of memory clients. Decisions about a minimum
required frequency are made based on the info from ACTMON. We can use
ACTMON as a thermal cooling device by limiting the required frequency.

Add documentation for new optional properties in the exynos bus nodes:
interconnects, #interconnect-cells, samsung,data-clock-ratio.
These properties allow to specify the SoC interconnect structure which
then allows the interconnect consumer devices to request specific

DDR3 SDRAM Standard (JESD79-3F) defines some standard speed bins for
DDR3 memories. The rk3399_dmc driver allows you to pass these values via
the device tree. For that purpose the devfreq/rk3399_dmc.txt binding
refers to a ddr.h file which does not exist. This patch adds the missing
defines in a include file called rk3399-ddr.h with the definition of
standard speed bins according to the ARM Trusted Firmware (ATF).

Fix this by replacing '@' with '-' as the OPP nodes will never have a
