will be the first block on the platform to be activated and signaled.
Under normal wait mode during cpu idle, the system can be woke up
by any enabled interrupts. Under standby or suspend mode, the system
can only be woke up by the pre-defined wakeup sources.

Under normal wait mode during cpu idle, the system can be woke up
by any enabled interrupts. Under standby or suspend mode, the system
can only be woke up by the pre-defined wakeup sources.

Good suggestion! Will change to support suspend states on imx7d.

IMX7D contains a new version of GPC IP block (GPCv2). It has two major
functions: power management and wakeup source management.
GPCv2 provides low power mode control for Cortex-A7 and Cortex-M4
domains. And it can support WAIT
the power states on IMX7D.
It currently supports SUSPEND_STANDBY and SUSPEND_MEM states.
