Qualcomm Snapdragon and Dragonwing SoC clock controllers

Clock controller support for Qualcomm's Snapdragon mobile and Dragonwing industrial/embedded systems-on-chip, which gate and configure the dozens of internal clocks that drive the CPU, GPU, modem, camera, and peripheral blocks on Qualcomm silicon. These chips power a huge share of Android phones, Chromebooks, automotive systems, and IoT/edge devices shipping today.

recommendation

It should stay because this is the upstream home for Qualcomm SoC clock support and remains under heavy active development, with 2025 patches adding new chips like the SM8750 and Kaanapali alongside ongoing fixes. Qualcomm continues to launch new Snapdragon flagships and Dragonwing industrial parts through 2025 and 2026, so removing this code would break an enormous installed base and cut off support for hardware still being sold new.

sources

  1. git.kernel.org

    Upstream activity is ongoing; the directory continues to receive fixes and new SoC enablement rather than removal work.

  2. qualcomm.com

    Qualcomm was still launching new Snapdragon flagship products for new devices in 2025, indicating the covered hardware family remained in active new-sale deployment.

  3. qualcomm.com

    Qualcomm was also launching new industrial/embedded processor lines in late 2025, supporting ongoing non-handset deployments that rely on Qualcomm SoC infrastructure.

  4. qualcomm.com

    Qualcomm described an expanded Linux-supporting industrial/embedded portfolio in 2026, reinforcing that this driver family still maps to active current hardware.

codex reasoning notes (technical)

This is a real driver directory with many platform clock-controller drivers and live entry-point macros (`rg` via shell confirmed). `lore-http` MCP was unavailable and `lei` was not installed, so I fell back to local `git -c safe.directory=... log -- drivers/clk/qcom`; that showed 2025-era fixes plus new Kaanapali/SM8750 support, which I tied to the canonical kernel.org log URL by canonical recall. The three Qualcomm URLs were obtained with `web.search_query` and show new Snapdragon/Dragonwing product launches in 2025-2026. I found no evidence of an upstream removal/deprecation series; active enablement for new Qualcomm SoCs strongly favors `keep`, with no natural replacement driver because this directory is the upstream implementation for Qualcomm clock controllers.
