Muhammed Asif developed and integrated PWM support for Microchip TCC peripherals within the zephyrproject-rtos/zephyr repository, focusing on Device Tree bindings and hardware configuration. He implemented YAML-based Device Tree Source bindings for the TCC G1 timer/counter, enabling flexible PWM control through configurable clock sources, prescalers, channels, and bit width. Asif also added Device Tree nodes for SAM D5x/E5x microcontrollers, defining memory addresses, interrupts, and clock sources to support multiple TCC instances. Working primarily in C and YAML, he expanded Zephyr’s hardware coverage, allowing broader adoption of PWM-based solutions on Microchip MCUs with minimal integration effort and robust configurability.
