Subject: [PATCH 00/10] Regulator ena_gpiod fixups

We noticed a refcounting fight between the kernel device
core devm_* and the regulator core refcounting, pertaining
to enable GPIOd:s that may be shared between multiple
regulators.

Fix this with a series that hand it all over to the
regulator core and remove any devm_* stuff pertaining
to these GPIOs.

This includes a patch to gpiolib to make gpiod_get_from_node()
available. Just go ahead and apply this to the regulator
tree.

If these need to go for fixes or not is up to the
regulator maintainer, but all commits have a proper
Fixes: tag in case they would. I have noted in the
four last commits that the gpiolib patch is a
prerequisite.

Linus Walleij (10):
