March 2026 monthly summary focusing on key accomplishments and business impact for bootlin/training-materials.

Monthly summary for 2025-10 focusing on RTC-related improvements in linux-riscv/linux. Implemented code quality and configuration cleanups to reduce build warnings and improve maintainability. Consolidated two maintenance changes: (1) make optee_rtc_pm_ops static to fix a sparse warning and limit symbol scope; (2) reorganize Kconfig symbols for Real-Time Clock drivers by moving HID Sensor RTC options to a more appropriate section, improving configuration clarity. These changes lay groundwork for safer feature integration across architectures and easier future maintenance.

September 2025 monthly summary for linux-riscv/linux focusing on stabilizing the I3C master driver by addressing header management and TX data path integrity. Implemented two critical fixes with clear commit traceability, improving compile reliability, runtime stability, and data integrity in the I3C subsystem.

July 2025: geerlingguy/linux focused on improving build stability for embedded driver code. Delivered a targeted bug fix to prevent unused variable warnings by scoping the pcf85063_config structure to be defined only when I2C or SPI master is enabled, ensuring clean builds across configurations. This change reduces build noise in CI, improves maintainability, and stabilizes behavior across hardware variants.
