pinctrl: core: Remove unused members from struct group_desc

2023-12-11T23:47:52Z

All drivers are converted to use embedded struct pingroup. Remove unused members from struct group_desc. Reviewed-by: Geert Uytterhoeven Signed-off-by: Andy Shevchenko Link: https://lore.kernel.org/r/20231211190321.307330-14-andriy.shevchenko@linux.intel.com Signed-off-by: Linus Walleij

pinctrl: core: Embed struct pingroup into struct group_desc

2023-12-11T23:47:52Z

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

2023-12-07T09:53:57Z

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: Convert unsigned to unsigned int

Simple type conversion with no functional change implied. While at it, adjust indentation where it makes sense. Signed-off-by: Andy Shevchenko Link: https://lore.kernel.org/r/20231129161459.1002323-24-andriy.shevchenko@linux.intel.com Signed-off-by: Linus Walleij

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

2022-11-14T13:19:33Z

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

2022-10-24T14:06:48Z

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

2019-12-30T13:27:17Z

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).
