Merge branches 'powercap', 'pm-domains', 'pm-em' and 'pm-opp'

2023-02-15T19:06:26+00:00

Merge updates of the powercap framework, generic PM domains, Energy
Model and operating performance points for 6.3-rc1:

 - Fix possible name leak in powercap_register_zone() (Yang Yingliang).

 - Add Meteor Lake and Emerald Rapids support to the intel_rapl power
   capping driver (Zhang Rui).

 - Modify the idle_inject power capping facility to support 100% idle
   injection (Srinivas Pandruvada).

 - Fix large time windows handling in the intel_rapl power capping
   driver (Zhang Rui).

 - Fix memory leaks with using debugfs_lookup() in the generic PM
   domains and Energy Model code (Greg Kroah-Hartman).

 - Add missing 'cache-unified' property in example for kryo OPP bindings
   (Rob Herring).

 - Fix error checking in opp_migrate_dentry() (Qi Zheng).

 - Remove "select SRCU" (Paul E. McKenney).

 - Let qcom,opp-fuse-level be a 2-long array for qcom SoCs (Konrad
   Dybcio).

  powercap: intel_rapl: Fix handling for large time window
  powercap: idle_inject: Support 100% idle injection
  powercap: intel_rapl: add support for Emerald Rapids

  drivers/opp: Remove "select SRCU"
  dt-bindings: opp: opp-v2-kryo-cpu: Add missing 'cache-unified' property in example

dt-bindings: opp: opp-v2-kryo-cpu: enlarge opp-supported-hw maximum

2023-02-14T05:21:58+00:00

Enlarge opp-supported-hw maximum value. In recent SoC we started
matching more bit and we currently match mask of 112. The old maximum of
7 was good for old SoC that didn't had complex id, but now this is
limiting and we need to enlarge it to support more variants.

Document all the various mask that can be used and limit them to only
reasonable values instead of using a generic maximum limit.

dt-bindings: opp: v2-qcom-level: Let qcom,opp-fuse-level be a 2-long array

2023-01-31T03:31:35+00:00

In some instances (particularly with CPRh) we might want to specifiy
more than one qcom,opp-fuse-level, as the same OPP subnodes may be
used by different "CPR threads". We need to make sure that
n = num_threads entries is legal and so far nobody seems to use more
than two, so let's allow that.

2022-12-27T02:57:42+00:00

The examples' cache nodes are incomplete as 'cache-unified' is a
required cache property for unified caches which an L2 cache certainly
is.

dt-bindings: drop redundant part of title (manual)

2022-12-16T18:51:43+00:00

The Devicetree bindings document does not have to say in the title that
it is a "Devicetree binding" or a "schema", but instead just describe
the hardware.

Manual updates to various binding titles, including capitalizing them.

Pull devicetree updates from Rob Herring:
 "DT Bindings:

   - Various LED binding conversions and clean-ups. Convert the
     ir-spi-led, pwm-ir-tx, and gpio-ir-tx LED bindings to schemas.
     Consistently reference LED common.yaml or multi-led schemas and
     disallow undefined properties.

   - Convert IDT 89HPESx, pwm-clock, st,stmipid02, Xilinx PCIe hosts,
     and fsl,imx-fb bindings to schema

   - Add ata-generic, Broadcom u-boot environment, and dynamic MTD
     sub-partitions bindings.

   - Make all SPI based displays reference spi-peripheral-props.yaml

   - Fix some schema property regex's which should be fixed strings or
     were missing start/end anchors

   - Remove 'status' in examples, again...

  DT Core:

   - Fix a possible NULL dereference in overlay functions

   - Fix kexec reading 32-bit "linux,initrd-{start,end}" values (which
     never worked)

   - Add of_address_count() helper to count number of 'reg' entries

   - Support .dtso extension for DT overlay source files. Rename staging
     and unittest overlay files.

   - Update dtc to upstream v1.6.1-63-g55778a03df61"

json-schema patterns by default will match anywhere in a string, so
typically we want at least the start or end anchored. Fix the obvious
cases where the anchors were forgotten.
