dt-bindings: cpufreq: Convert ti-cpufreq to json schema

2023-08-21T05:53:34+00:00

Move the ti-cpufreq binding over to opp and convert the free text binding to json-schema. Reviewed-by: Dhruva Gole Signed-off-by: Nishanth Menon Reviewed-by: Krzysztof Kozlowski Signed-off-by: Viresh Kumar

dt-bindings: opp: Convert ti-omap5-opp-supply to json schema

2023-08-21T05:53:34+00:00

Rename ti-omap5-opp-supply to be bit more generic omap-opp-supply and convert the free text binding to json-schema. Reviewed-by: Krzysztof Kozlowski Reviewed-by: Dhruva Gole Signed-off-by: Nishanth Menon Signed-off-by: Viresh Kumar

dt-bindings: opp: Increase maxItems for opp-hz property

2023-07-25T04:10:57+00:00

Current limit of 16 will be exhausted by platforms specifying the frequency for 9 clocks using opp-hz, like Qcom SDM845 SoC. For instance, specifying the frequency for 9 clocks with 64bit specifier as below would consume (9 * 2 = 18) items. opp-50000000 { opp-hz = /bits/ 64 <50000000>, /bits/ 64 <0>, /bits/ 64 <0>, /bits/ 64 <37500000>, /bits/ 64 <0>, /bits/ 64 <0>, /bits/ 64 <0>, /bits/ 64 <0>, /bits/ 64 <75000000>; }; So let's increase the limit to 32 which should be enough for most platforms (hopefully).

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: powercap: intel_rapl: Fix handling for large time window powercap: idle_inject: Support 100% idle injection powercap: intel_rapl: add support for Emerald Rapids powercap: intel_rapl: add support for Meteor Lake powercap: fix possible name leak in powercap_register_zone() * pm-domains: PM: domains: fix memory leak with using debugfs_lookup() * pm-em: PM: EM: fix memory leak with using debugfs_lookup() * pm-opp: OPP: fix error checking in opp_migrate_dentry() dt-bindings: opp: v2-qcom-level: Let qcom,opp-fuse-level be a 2-long array 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.

dt-bindings: opp: opp-v2-kryo-cpu: Add missing 'cache-unified' property in example

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. Signed-off-by: Rob Herring Signed-off-by: Viresh Kumar

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

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.
