2023-05-05dt-bindings: perf: riscv,pmu: fix property dependenciesConor Dooley1-1/+0
Seemingly I mis-implemented the dependencies here. The OpenSBI docs only point out that the "riscv,event-to-mhpmcounters property is mandatory if riscv,event-to-mhpmevent is present". It never claims that riscv,event-to-mhpmcounters requires riscv,event-to-mhpmevent. Drop the dependency of riscv,event-to-mhpmcounters on riscv,event-to-mhpmevent.

2023-01-17dt-bindings: riscv: add SBI PMU event mappingsConor Dooley1-0/+161
The SBI PMU extension requires a firmware to be aware of the event to counter/mhpmevent mappings supported by the hardware. OpenSBI may use DeviceTree to describe the PMU mappings. This binding is currently described in markdown in OpenSBI (since v1.0 in Dec 2021) & used by QEMU since v7.2.0. Import the binding for use while validating dtb dumps from QEMU and upcoming hardware (eg JH7110 SoC) that will make use of the event mapping.

2022-03-07nds32: Remove the architectureAlan Kao1-17/+0
The nds32 architecture, also known as AndeStar V3, is a custom 32-bit RISC target designed by Andes Technologies. Support was added to the kernel in 2016 as the replacement RISC-V based V5 processors were already announced, and maintained by (current or former) Andes employees. As explained by Alan Kao, new customers are now all using RISC-V, and all known nds32 users are already on longterm stable kernels provided by Andes, with no development work going into mainline support any more. While the port is still in a reasonably good shape, it only gets worse over time without active maintainers, so it seems best to remove it before it becomes unusable. As always, if it turns out that there are mainline users after all, and they volunteer to maintain the port in the future, the removal can be reverted.

2022-02-04dt-bindings: Improve phandle-array schemasRob Herring1-0/+2
The 'phandle-array' type is a bit ambiguous. It can be either just an array of phandles or an array of phandles plus args. Many schemas for phandle-array properties aren't clear in the schema which case applies though the description usually describes it. The array of phandles case boils down to needing: items: maxItems: 1 The phandle plus args cases should typically take this form: items: - items: - description: A phandle - description: 1st arg cell - description: 2nd arg cell With this change, some examples need updating so that the bracketing of property values matches the schema.

2021-06-21dt-bindings: Drop redundant minItems/maxItemsRob Herring1-1/+0
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.

Document the requirements for the CMN-600 DT binding. The internal topology is almost entirely discoverable by walking a tree of ID registers, but sadly both the starting point for that walk and the exact format of those registers are configuration-dependent and not discoverable from some sane fixed location.
