  1. On i.MX8MP, GPIOs are owned by Linux (A53) by default.
    If the Cortex-M7 needs them—especially for interrupts—you must release them in the device tree:

    • Remove pinmux
    • Remove GPIO references
    • Disable the GPIO controller if needed

    This prevents A53/M7 resource conflicts and ensures real-time reliability.
