Some gpio-regmap consumers share their regmap with a parent device that may be runtime suspended. GPIO register accesses must resume that device first. Add an optional pm_dev field and acquire it before register translation or access. Release it using runtime autosuspend after each operation. Keep the device active across the complete direction-output sequence and propagate failure when setting the initial output value.
