Developed initial support for the Raspberry Pi Power HAT within the geerlingguy/linux repository, focusing on hardware integration and embedded systems. The work involved creating device tree overlays to support both bottom and top mounting modes, enabling the i2c_arm interface to facilitate programmatic power management for the HAT. Updates to the Makefile and README ensured clear documentation and streamlined integration for future users. Leveraging expertise in Device Tree and Device Tree Overlay, the implementation enhanced hardware compatibility for Raspberry Pi deployments. The contribution was delivered as a cohesive feature, reflecting a focused approach to embedded Linux development and hardware enablement.
