dt-bindings: perf: riscv,pmu: fix property dependencies

2023-05-17T12:01:46Z

[ Upstream commit 4d276e4d3bb4a503e75086faab54f92c0a8fd368 ] 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.

dt-bindings: riscv: add SBI PMU event mappings

2023-01-17T20:43:55Z

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.

dt-bindings: perf: arm-cmn: Add CMN-650 and CMN-700

2022-05-06T14:07:25Z

If you were to guess from the product names that CMN-650 and CMN-700 are the next two evolutionary steps of Arm's enterprise-level interconnect following on from CMN-600, you'd be pleasantly correct. Add them to the DT binding.

Pull devicetree updates from Rob Herring: - Add Krzysztof Kozlowski as co-maintainer for DT bindings providing much needed help. - DT schema validation now takes DTB files as input rather than intermediate YAML files. This decouples the validation from the source level syntax information. There's a bunch of schema fixes as a result of switching to DTB based validation which exposed some errors and incomplete schemas and examples. - Kbuild improvements to explicitly warn users running 'make dt_binding_check' on missing yamllint - Expand DT_SCHEMA_FILES kbuild variable to take just a partial filename or path instead of the full path to 1 file. - Convert various bindings to schema format: mscc,vsc7514-switch, multiple GNSS bindings, ahci-platform, i2c-at91, multiple UFS bindings, cortina,gemini-sata-bridge, cortina,gemini-ethernet, Atmel SHA, Atmel TDES, Atmel AES, armv7m-systick, Samsung Exynos display subsystem, nuvoton,npcm7xx-timer, samsung,s3c2410-i2c, zynqmp_dma, msm/mdp4, rda,8810pl-uart - New schemas for u-boot environment variable partition, TI clksel - New compatible strings for Renesas RZ/V2L SoC - Vendor prefixes for Xen, HPE, deprecated Synopsys, deprecated HiSilicon - Add/fix schemas for QEMU Arm 'virt' machine - Drop unused of_alias_get_alias_list() function - Add a script to check DT unittest EXPECT message output.
