commit a4c47746124e120e933693eb86dc1c54b499fa07 Author: raiden00pl <[email protected]> AuthorDate: Thu Jun 11 20:14:46 2026 +0200 arch/nrf91: grant GPIOTE1 to the non-secure domain Add CONFIG_NRF91_GPIOTE1_NS so the secure firmware can hand the non-secure GPIOTE instance to the application, allowing a non-secure app to use GPIO interrupts.
