PROFILE
Clark Kim
Clark Kim developed end-to-end support for the NXP PCA9422 Power Management IC within the Zephyr project’s nxp-upstream/zephyr repository, targeting the MIMXRT700 EVK (CM33 CPU0) platform. He designed and implemented a comprehensive driver stack in C, including MFD, charger, and regulator components, and integrated these with the device tree and build system using conditional compilation for CONFIG_MFD_PCA9422. Clark also created board-level PMIC instances and APIs to manage interrupts, ensuring compatibility with Zephyr’s upstream practices. His work demonstrated depth in embedded systems, device driver development, and hardware configuration, enabling robust power management and facilitating real hardware bring-up.
