dt-bindings: opp: adreno: Update regex of OPP entry

2025-07-04T18:09:43+00:00

In some cases, an OPP may have multiple variants to describe the differences in the resources between SKUs. As an example, we may want to vote different peak bandwidths in different SKUs for the same frequency and the OPP node names can have an additional integer suffix to denote this difference like below: opp-666000000-0 { opp-hz = /bits/ 64 <666000000>; opp-level = ; opp-peak-kBps = <8171875>; qcom,opp-acd-level = <0xa82d5ffd>; opp-supported-hw = <0xf>; }; /* Only applicable for SKUs which has 666Mhz as Fmax */ opp-666000000-1 { opp-hz = /bits/ 64 <666000000>; opp-level = ; opp-peak-kBps = <16500000>; qcom,opp-acd-level = <0xa82d5ffd>; opp-supported-hw = <0x10>; }; Update the regex to allow this usecase.

dt-bindings: opp: Add v2-qcom-adreno vendor bindings

2025-05-04T16:20:29+00:00

Add a new schema which extends opp-v2 to support a new vendor specific property required for Adreno GPUs found in Qualcomm's SoCs. The new property called "qcom,opp-acd-level" carries a u32 value recommended for each opp needs to be shared to GMU during runtime. Also, update MAINTAINERS file include the new opp-v2-qcom-adreno.yaml.

dt-bindings: arm/cpus: Add missing properties

2025-04-22T14:40:07+00:00

The Arm CPU schema is missing a number of properties already in use. This has gone unnoticed as extra properties have not been restricted. Add a missing reference to cpu.yaml, and add all the missing properties. As "clock-latency" and "voltage-tolerance" are related to opp-v1, add those properties to the opp-v1.yaml schema. With this, other properties can be prevented from creeping in with 'unevaluatedProperties: false'.

dt-bindings: Reference opp-v1 schema in CPU schemas

2025-04-22T14:40:07+00:00

The opp-v1 binding is only used in MIPS and arm32 CPU nodes, so add a $ref to it in the CPU schemas and drop the "select". As opp-v1 has long been deprecated, mark it as such.

dt-bindings: opp: h6: Add A100 operating points

2025-01-09T22:52:29+00:00

The A100, similar to the H6 and H616, use an NVMEM value to determine speed binnings. The method used is similar to that of the H6. However, the information is stored at a slightly different bit offset. Add a new compatible for the A100.

dt-bindings: opp: operating-points-v2-ti-cpu: Describe opp-supported-hw

2024-10-01T09:27:08+00:00

It seems like we missed migrating the complete information from the old DT binding where we had described what the opp-supported-hw is supposed to describe. Hence, bring back the description from the previous binding to the current one along with a bit more context on what the values are supposed to be.

dt-bindings: opp: Describe H616 OPPs and opp-supported-hw

2024-04-19T07:04:27+00:00

Compared to the existing Allwinner H6 OPP scheme, the H616 uses a similar NVMEM based mechanism to determine the silicon revision, which is required to select the right frequency / voltage pair for the OPPs. However it limits the maximum frequency for some speed bins, also seems to not support all frequencies in all speed bins, which requires us to introduce the opp-supported-hw property. Add this property to the list of allowed properties, also drop the requirement for the revision specific opp-microvolt properties, since they might not be needed if using opp-supported-hw. Also use to opportunity to adjust some wording, and drop a sentence referring to the Linux driver and the OPP subsystem. Shorten the existing example and add another example, showcasing the opp-supported-hw property.
