Subject: [PATCH v2 00/62] pinctrl: don't use GPIOLIB global numberspace in helpers
From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>
We have a set of pinctrl helpers for GPIOLIB drivers that take a number
from the global GPIO numberspace as argument. We are trying to get rid
of this global numbering. Let's rework these helpers to use the
recommended gpio_chip + controller-relative offset instead.
This work is split into phases: first let's introduce the new variants
of the helpers. Next: let's convert all users one-by-one for easier
review. After that let's remove the old helpers and rename the new
variants to take the place of the old ones. Finally convert static
functions in pinctrl/core.c to using the same signature and to top it
off, let's remove now redundant wrappers around the pinctrl_helpers.
This series introduces no functional changes in drivers so I decided to
not spam every single driver maintainer anymore.
v1 -> v2:
- drop the conversion to using cleanup.h helpers as this is not the
subject of this series
- split the patch renaming the new variants to the old names into
several patches that perform the operation step by step for easier
review
- collect review tags and acks
- add follow-up patches that drop the wrappers around pinctrl helpers
where applicable (where all the wrappers do is call the helper)
- fix build error with PINCTRL disabled
