domain (or PERF for that matter) and switch the GPIOs to a _suspend
state - is that by design?
With PD_FLAG_DEV_LINK_ON enabled, every pm_runtime_get_sync() or pm_runtime_put_sync() on the device triggers a corresponding genpd on/off transition. These transitions are translated into SCMI power‑domain commands, allowing the firmware (GearVM) to perform the actual enable/disable sequencing.
Thanks,
Praveen.
