> Suspend may fail on i.MX8QM when Falling Edge is used as a pad
> wakeup trigger due to a hardware bug in the detection logic. Since the
> hardware does not support Both Edge wakeup, remap requests for
> Both Edge to Rising Edge by default to avoid hitting this issue.
> 
> A warning is emitted when Falling Edge is selected on i.MX8QM.
