pinctrl: core: Embed struct pingroup into struct group_desc

2023-12-11T23:47:52+00:00

struct group_desc is a particular version of the struct pingroup
with associated opaque data. Start switching pin control core and
drivers to use it explicitly.

pinctrl: core: Make pins const unsigned int pointer in struct group_desc

2023-12-07T09:53:57+00:00

It's unclear why it's not a const unsigned int pointer from day 1.
Make the pins member const unsigned int pointer in struct group_desc.
Update necessary APIs.

pinctrl: Move for_each_maps() to namespace and hide iterator inside

2022-11-14T13:19:33+00:00

First of all, while for_each_maps() is private to pin control subsystem
it's still better to have it put into a namespace.

Besides that, users are not relying on iterator variable, so hide it
inside for-loop.

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).
