Developed end-to-end support for the NXP PCA9422 Power Management IC within the Zephyr ecosystem, focusing on the MIMXRT700 EVK (CM33 CPU0) platform in the nxp-upstream/zephyr repository. Delivered a comprehensive driver suite in C, including MFD, charger, and regulator components, and integrated these with the board-level device tree using DTS. Implemented APIs for managing PMIC interrupts with conditional compilation under CONFIG_MFD_PCA9422, ensuring compatibility with Zephyr’s build system and upstream practices. All changes were thoroughly documented with clear commit references, supporting traceability and review. The work emphasized embedded systems, hardware configuration, and RTOS integration.
