    Linux kernel Devicetree sources: With my recent patches entire ARM, arm64 (except Broadcom Stingray and Apple) and RISC-V DTS files pass the dt-check-style linter, in default relaxed mode, so any new DTS is expected to not introduce new warnings. IOW, in your contributions be sure that new DTS is dt-check-style warning-free. I am working on fixing false positives for the strict mode and have some successes, but that is not yet ready.

    If someone asked me 5 years ago, I would not believe that I could produce such a statement about major SoC vendor: https://lore.kernel.org/all/2509536d-cdec-448d-bf20-80d2b3d6728a@kernel.org/ Qualcomm and Linaro were upstreaming before significant amount of code to the Linux kernel for supporting their SoCs , but around 2021-2022 things changed significantly. Just to recap major milestones of: 2022 November: One day after public announcement of new Snapdragon 8 Gen 2 flagship SoC (SM8550), Qua...

    Some moron is running out of water bodies to rename after his ego. There was a gulf, now a lake. So I guess there is gonna be a river, sea and ocean soon? I&amp;#39;m happily avoiding all technical conferences as a speaker in a country ruled by said moron.

    October is coming which means Linux Plumbers Conference 2026 in Prague, where I am running Devicetree Microconference track (6th of Oct). There will be talks about: - Current progress with OF_UPSTREAM (@superna9999), - Status of getting DT bindings compliance (me), - Combining ACPI with Devicetree because the more firmware the merrier (Srinivas Kandagatla), - Upstreaming your DTS faster than maintainers can review (Amit Kucheria), - The never-ending saga of hot-pluggable extension boards (Hervé...

    @jann If only there was one tree for entire kernel, where everyone would be merging and managing simultaneously... if only ever someone invented a non-distributed revision control system which would help in achieving that. That distributed thing is also so annoying!

    Continuing PyTorch / Linux Foundation database of harvested emails and sending advertisements to them - https://social.kernel.org/notice/B3bhz39OUEdNndylVI Linux Foundation apologized for &amp;quot;internal marketing operations error&amp;quot; and that &amp;quot;Your email address, along with those of other kernel maintainers, was included in a dataset from a third-party data provider that was improperly imported into our marketing systems without consent verification.&amp;quot; No name for 3r...

    Go Beavers! I mean, the true beavers, the greatest ecosystem engineers, which are vital in bringing diversity, richness, and healing degraded landscapes. “Beaver settlements triple in 15 years in Switzerland” https://www.swissinfo.ch/eng/beavers-increase-threefold-in-15-years-in-switzerland/48657934 If you want to learn more, why beavers are important, I recommend Andrew Millison’s: https://youtu.be/43bmtqKDhBE

    With v6.5-rc1 merge window, my remaining few fixes for Samsung Exynos SoC dtbs_check compliance were merged. This means that with v6.5-rc1 all ARM and ARM64 Samsung Exynos SoC Devicetree sources (DTS) pass in-kernel Devicetree bindings compliance tests. I can finally enable a builder testing mainline DTS for this: https://krzk.eu/#/builders/92 https://krzk.eu/#/builders/91 https://github.com/krzk/tools/commit/743f694cfe4d18dd5f92728967aa762edd59c84e P.S. The ARM64 Exynos DTS was actually compli...

    New release: neard v0.20, the user-space counterpart of Linux NFC stack The release includes a few minor fixes. Source code release: https://web.git.kernel.org/pub/scm/network/nfc/neard.git/tag/?h=v0.20 https://web.git.kernel.org/pub/scm/network/nfc/neard.git/snapshot/neard-0.20.tar.gz I should have released it much earlier, though. I think this release thanks to Mark Greer finally dumps Python 2 dependency - last blocker of packaging for Debian. Anyone would like to revive the Debian package...

    Since a year we got some contributions for converting Devicetree bindings from TXT to DT schema as part of some sort mentorship programs (e.g. GSoC). This is great although leads to some misunderstandings in that work, considering mentorships did not ask DT maintainers about some sort of guidance. To clarify: 1. Please convert bindings which have active DTS users. First choose bindings with DTS built by arm64 defconfig, then next choice by arm multi_v7 defconfig. Then any other ARM or different...
