Subject: [PATCH v2] gpio: mxc: map Both Edge pad wakeup to Rising
Edge
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.
Fixes: f60c9eac54af ("gpio: mxc: enable pad wakeup on i.MX8x
platforms")
