The GENI serial driver currently handles power resource management through calls to the statically defined geni_serial_resources_on() and geni_serial_resources_off() functions. This approach reduces modularity and limits support for platforms with diverse power management mechanisms, including resource managed by firmware. Improve modularity and enable better integration with platform-specific power management, introduce support for runtime PM. Use pm_runtime_resume_and_get() and pm_runtime_put_sync() within the qcom_geni_serial_pm() callback to control resource power state transitions based on UART power state changes.
