Re: [PATCH v3 12/14] gpio: regmap: Add optional runtime PM support

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.

I like it.

This also looks like it could be merged orthogonally to the GPIO
tree though I see there are runtime dependencies. What about
Bartosz queue the two GPIO patches on an immutable branch
for Jonathan to pick?
