pinctrl: core: add devm_pinctrl_register_mappings()

Using devm_pinctrl_register_mappings(), the core can automatically
unregister pinctrl mappings.

pinctrl: remove extern specifier for functions in machine.h

2025-05-21T08:09:41+00:00

Extern is the default specifier for a function, no need to define it.

pinctrl: Convert unsigned to unsigned int

2023-12-04T14:32:42+00:00

Simple type conversion with no functional change implied.
While at it, adjust indentation where it makes sense.

pinctrl: Replace kernel.h by what is actually being used

2023-10-03T13:29:30+00:00

The kernel.h is a mess of unrelated things and we only used it
as a proxy to array_size.h, hence switch from former to the latter.

While at it, group and sort the headers where it makes sense.

pinctrl: Clean up headers

2022-10-24T14:06:48+00:00

There is a few things done:
- include only the headers we are direct user of
- when pointer is in use, provide a forward declaration
- add missing headers
- group generic headers and subsystem headers
- sort each group alphabetically

While at it, fix some awkward indentations.

pinctrl: Allow modules to use pinctrl_[un]register_mappings

2019-12-30T13:27:17+00:00

Currently only the drivers/pinctrl/devicetree.c code allows registering
pinctrl-mappings which may later be unregistered, all other mappings
are assumed to be permanent.

Non-dt platforms may also want to register pinctrl mappings from code which
is build as a module, which requires being able to unregister the mapping
when the module is unloaded to avoid dangling pointers.

To allow unregistering the mappings the devicetree code uses 2 internal
functions: pinctrl_register_map and pinctrl_unregister_map.

pinctrl_register_map allows the devicetree code to tell the core to
not memdup the mappings as it retains ownership of them and
pinctrl_unregister_map does the unregistering, note this only works
when the mappings where not memdupped.

The only code relying on the memdup/shallow-copy done by
pinctrl_register_mappings is arch/arm/mach-u300/core.c this commit
replaces the __initdata with const, so that the shallow-copy is no
longer necessary.

After that we can get rid of the internal pinctrl_unregister_map function
and just use pinctrl_register_mappings directly everywhere.

This commit also renames pinctrl_unregister_map to
pinctrl_unregister_mappings so that its naming matches its
pinctrl_register_mappings counter-part and exports it.

Together these 2 changes will allow non-dt platform code to
register pinctrl-mappings from modules without breaking things on
module unload (as they can now unregister the mapping on unload).

pinctrl: add pinctrl_provide_dummies interface for platforms to use

2012-04-26T21:31:04+00:00

Add a interface pinctrl_provide_dummies for platform to indicate
whether it needs use pinctrl dummy state.

ChangeLog v3->v4:
* remove dummy gpio support in pinctrl subsystem.
  Let gpio driver decide whether it wants to use pinctrl gpio mux
  function.
ChangeLog v2->v3:
* Also changed the missed pinctrl gpio APIs in v1.
ChangeLog v1->v2:
* Based on sascha's suggestion, drop using kconfig since it will hide
  pinctrl errors on all other boards.
  See: https://lkml.org/lkml/2012/4/18/282
  It seemed both Linus and Stephen agreed with this way, so i'm ok
  with it too.
* Add dummy gpio support.
  pinctrl gpio in the same situation as state.
* Patch name changed.
  Original is pinctrl: handle dummy state in core.
* Split removing old dt dummy interface into a separate patch
