Re: [PATCH v6 3/3] gpio: search for gpio label if gpio is not found through bank name

dm_gpio_lookup_name() searches for a gpio through the bank name. But we have also gpio labels, and it makes sense to search for a gpio also in the labels we have defined, if no gpio is found through the bank name definition.

This is useful for example if you have a wp pin on different gpios on different board versions.

If dm_gpio_lookup_name() searches also for the gpio labels, you can give the gpio an unique label name and search for this label, and do not need to differ between board revisions.
