Aug 1, 2025

In August 2025, contributed to the nrfconnect/sdk-zephyr repository by cleaning up the TISCI header: removed duplicate tisci_cmd_get_fwl_region declarations to fix documentation build errors and improve header accuracy. The change, tracked in commit f6bee983bc5a67ab47e99c488486c28d2deee9d7 (drivers: firmware: remove duplicate function definitions), reduces documentation build failures, simplifies maintenance, and improves CI reliability for Zephyr integration with TISCI-enabled devices. This work enhances code hygiene and documentation consistency, supporting smoother onboarding for contributors and faster iteration on firmware driver work.
