2025-07-30of: Clarify OF device context in of_match_device() commentBagas Sanjaya
Open Firmware abbreviation (OF) in of_match_device() comment is written in lowercase instead, which is mistaken for prepositional word "of" ([1], [2], [3], [4]) duplicate. Clarify the context.

2025-07-28dt-bindings: Correct indentation and style in DTS exampleKrzysztof Kozlowski
DTS example in the bindings should be indented with 2- or 4-spaces and aligned with opening '- |', so correct any differences like 3-spaces or mixtures 2- and 4-spaces in one binding. No functional changes here, but saves some comments during reviews of new patches built on existing code.

2025-07-25dt-bindings: interrupt-controller: Add missing Xilinx INTC bindingMichal Simek
Add missing description for AMD/Xilinx interrupt controller. The binding is used by Microblaze before dt-binding even existed but never been documented properly. IP acts as primary interrupt controller on Microblaze systems or can be used as secondary interrupt controller on ARM based systems like Zynq, ZynqMP, Versal or Versal Gen 2. Also as secondary interrupt controller on Microblaze-V (Risc-V) systems. Over the years IP exists in multiple variants based on attached bus as OPB, PLB or AXI that's why generic filename is used. Property xlnx,kind-of-intr is in hex because every bit position corresponds to interrupt line. Controller support mixing edge or level interrupts together and this is the property which distinguish them.

2025-07-14docs: dt: writing-bindings: Document compatible and filename namingKrzysztof Kozlowski
Document established Devicetree bindings maintainers review practices: 1. Compatibles should not use bus suffixes to encode the type of interface, because the parent bus node defines that interface, e.g. "vendor,device" instead of "vendor,device-i2c" + "vendor,device-spi". 2. If the compatible represents the device as a whole, it should not contain the type of device in the name. 3. Filenames should match compatible. The best if match is 100%, but if binding has multiple compatibles, then one of the fallbacks should be used. Alternatively a genericish name is allowed if it follows "vendor,device" style.

2025-07-08docs: dt: writing-bindings: Express better expectations of "specific"Krzysztof Kozlowski
Devicetree bindings are supposed to be specific in terms of compatibles and other properties. Short "specific" has many implications, so extend the description to cover them: 1. Mention no family names and avoid generic SoC fallbacks in compatible. The list grew, mixing DO's and DON'T's, so split it into multiple items. 2. No properties implied by the compatible. 3. Document desired lack of ABI impact and acceptable solution if such needs arises: clearly marking it in commit msg. All above follows established Devicetree bindings maintainers review practice, so no new rules in practice are introduced here.

2025-06-08tools/power turbostat: Avoid probing the same perf countersZhang Rui
For the RAPL package energy status counter, Intel and AMD share the same perf_subsys and perf_name, but with different MSR addresses. Both rapl_counter_arch_infos[0] and rapl_counter_arch_infos[1] are introduced to describe this counter for different Vendors. As a result, the perf counter is probed twice, and causes a failure in in get_rapl_counters() because expected_read_size and actual_read_size don't match. Fix the problem by skipping the already probed counter. Note, this is not a perfect fix. For example, if different vendors/platforms use the same MSR value for different purpose, the code can be fooled when it probes a rapl_counter_arch_infos[] entry that does not belong to the running Vendor/Platform. In a long run, better to put rapl_counter_arch_infos[] into the platform_features so that this becomes Vendor/Platform specific.

2025-06-08tools/power turbostat: Allow probing RAPL with platform_features->rapl_msrs ↵Zhang Rui
cleared platform_features->rapl_msrs describes the RAPL MSRs supported. While RAPL Perf counters can be exposed from different kernel backend drivers, e.g. RAPL MSR I/F driver, or RAPL TPMI I/F driver. Thus, turbostat should first blindly probe all the available RAPL Perf counters, and falls back to the RAPL MSR counters if they are listed in platform_features->rapl_msrs. With this, platforms that don't have RAPL MSRs can clear the platform_features->rapl_msrs bits and use RAPL Perf counters only.

2025-06-08tools/power turbostat: Introduce add_msr_counter()Zhang Rui
probe_rapl_msr() is reused for probing RAPL MSR counters, cstate MSR counters and MPERF/APERF/SMI MSR counters, thus its name is misleading. Similar to add_perf_counter(), introduce add_msr_counter() to probe a counter via MSR. Introduce wrapper function add_rapl_msr_counter() at the same time to add extra check for Zero return value for specified RAPL counters. No functional change intended.
