Month 2025-10: Delivered MIPI DSI display connectivity enhancements for STM32-based platforms in Zephyr RTOS. Key deliverables include: (1) MIPI DSI support for STM32U5 implemented via driver updates and device-tree bindings, including DSI PLL/PHY configuration and clock source settings (4 commits). (2) MIPI DSI support for STM32U59x/5Ax added with a dedicated DSI host controller device-tree node and wiring (2 commits). These changes enable native display connectivity on STM32 boards and form the foundation for graphics-rich user experiences. The work improves hardware compatibility, reduces integration risk for new boards, and demonstrates strong proficiency in embedded Linux kernel development, device-tree bindings, and MIPI-DSI engineering.
