During March 2026, Basile Gruner focused on improving device tree reliability in the nxp-upstream/zephyr repository by addressing a bug in the STM32N6 clock multiplexer binding. He corrected the device-tree property name from 'div' to 'ic-div' within the st,stm32n6-ic-clock-mux.yaml file, ensuring the binding accurately reflected the hardware configuration. This change reduced the risk of misconfiguration during device-tree generation and system boot, leading to more reliable clock setup for STM32N6-based embedded systems. Basile applied his expertise in YAML configuration and device tree bindings, documenting the update clearly and maintaining consistency across the repository’s embedded systems configuration files.
