January 2026 monthly summary for zephyr project focused on delivering base support for NXP SC18IS606 SPI/GPIO bridge within the MFD (multi-function device) framework, including device integration, GPIO controller, and test scaffolding. The work establishes a foundation for SPI/GPIO bridging in MFD and enables broader adoption in relevant platforms, with improvements to code organization and test readiness.

October 2025 monthly summary for the renesas/zephyr repository. Delivered reliability and compatibility improvements for the SDMA video path and sensor formats. Implemented automatic fallback to the first supported sensor format in the mcux_sdma driver and hardened the MCXN236 video capture sample for SDMA by configuring a standard frame size. These changes reduce runtime failures, improve cross-board compatibility, and enhance observability through fallback failure logging.

August 2025 monthly summary: Delivered the initial NXP SC18IS606 SPI bridge driver for the renesas/zephyr repository, enabling SPI over I2C communication with full driver sources, Kconfig options, and device tree bindings. Added a test overlay to validate SPI behavior and CI coverage. This work provides immediate hardware compatibility for SPI devices on SC18IS606-based platforms, accelerating integration for customers and expanding Zephyr's hardware support.
