Specifically "pvs[0-9]" something entirely new. Best regards, Krzysztof

No. It should be fixed instead (enum applies > to items). Currenlty this bindings are only usable for msm8996/msm8996pro. As such we listed opp-supported-hw values that are applicable to this platform. This series adds support for apq8064 platform, which will add new items to this enum. I think it is not very sensible to list all of them here. However granted there is already a good enough base type definition, I think it would be better to drop the $ref, drop the enum, add ': true' (is it necessary if we have a description already?) and expand documentation. > >> >> clock-latency-ns: true >> >> required-opps: true >> >> + patternProperties: >> + '^opp-microvolt-speed[0-9]+-pvs[0-9]+$': true > > I don't think it is a common property, so it needs description and > specific type.

I think it is not very sensible to list all of them here. Sure, but this is uint32-matrix, so don't change the type to something else. > > However granted there is already a good enough base type definition, I > think it would be better to drop the $ref, drop the enum, add ': true' > (is it necessary if we have a description already?) and expand > documentation. Probably this should be constrained to only one value with: items: - items: - description: foo bar Best regards, Krzysztof

Exted the opp-v2-kryo-cpu.yaml to support defining OPP tables for the previous generation of Qualcomm CPUs, 32-bit Krait-based platforms. It makes no sense to use 'operating-points-v2-kryo-cpu' compatibility node for the Krait cores. Add support for the Krait-specific 'operating-points-v2-krait-cpu' compatibility string and the relevant opp-microvolt subclasses properties.
