PROFILE
Manimaran A
Manimaran contributed to the nxp-upstream/zephyr repository by developing hardware-facing features for Microchip MEC devices over a two-month period. He enhanced the MEC EEPROM driver, updating device tree settings and configuring pin control to support internal EEPROM access on MEC5 hardware, which improved reliability and hardware compatibility. In a subsequent effort, he delivered keyboard scanning driver enhancements, enabling 18×8 matrix support with sleep-mode power efficiency across MEC174x/5x/165xb series. His work leveraged C programming, Zephyr OS, and device tree configuration, focusing on maintainability and cross-series enablement. The contributions addressed platform coverage and low power design without explicit bug fixes.

Feb 1, 2026February 2026 (2026-02) — Focused on delivering a hardware-facing feature in the Zephyr upstream for Microchip MEC EEPROM. Implemented enhancements to the EEPROM driver by updating device tree settings (PCR and GIRQ properties) and configuring pinctrl for internal MEC EEPROM access, preparing MEC5 hardware support. This work improves reliability and hardware compatibility, enabling smoother MEC EEPROM integration in subsequent releases. No explicit major bugs fixed this month.
