Add YAML device tree bindings for NVDEC, now in a more appropriate
place compared to the old textual Host1x bindings.

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)"

dt-bindings: Drop redundant minItems/maxItems

2021-06-21T19:56:46+00:00

If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.

This condition is partially checked with the meta-schema already, but
only if both 'minItems' and 'maxItems' are equal to the 'items' length.
An improved meta-schema is pending.
