Worked on the geerlingguy/linux repository to enhance the stability and recovery of Tegra I2C controllers in embedded systems. Developed an internal software reset mechanism and made the reset property optional, supporting platforms with limited external reset controls. Improved ACPI reset error handling by switching to device_reset, ensuring accurate error code interpretation across diverse environments. Simplified DMA transfer logic by removing redundant dma_sync_* calls for buffers allocated with dma_alloc_coherent, reducing complexity and potential data transfer issues. The work demonstrated strong skills in C, kernel development, and device driver engineering, focusing on robust error handling and maintainable embedded system solutions.
