March 2026 monthly summary focusing on key accomplishments and business value across the nxp-upstream/zephyr repository. Delivered a critical compatibility bug fix for the watchdog library, preventing build warnings when no driver is selected and CONFIG_WATCHDOG is enabled. This aligns watchdog behavior with other driver libraries, improving build reliability, upstream compatibility, and developer experience. The change reduces CI noise, lowers integration risk for systems relying on watchdog, and maintains consistency across Zephyr device drivers.

January 2026: Delivered CI test coverage for ADS79xx ADC devices in the Zephyr project, integrating ADS79xx tests into the CI build to validate driver compatibility across ADS79xx variants. This strengthens automated validation and accelerates feedback on driver changes.

December 2025 — Zephyr RTOS: Delivered initial TI ADS79xx ADC driver to expand SPI-based ADC support. The driver enables auto-1 mode operation with multiple resolutions (12/10/8-bit) and configurable channels for the TI ADS79xx family, facilitating faster sensor integration and more configurable data capture pipelines for embedded products.
