2023-10-30pinctrl: Use device_get_match_data()Rob Herring1-5/+2
Use preferred device_get_match_data() instead of of_match_device() to get the driver match data. With this, adjust the includes to explicitly include the correct headers.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for the v5.3 kernel cycle: Core changes: - Device links can optionally be added between a pin control producer and its consumers. This will affect how the system power management is handled: a pin controller will not suspend before all of its consumers have been suspended. This was necessary for the ST Microelectronics STMFX expander and need to be tested on other systems as well: it makes sense to make this default in the long run. Right now it is opt-in per driver. - Drive strength can be specified in microamps. With decreases in silicon technology, milliamps isn't granular enough, let's make it possible to select drive strengths in microamps. Right now the Meson (AMlogic) driver needs this. New drivers: - New subdriver for the Tegra 194 SoC. - New subdriver for the Qualcomm SDM845. - New subdriver for the Qualcomm SM8150. - New subdriver for the Freescale i.MX8MN (Freescale is now a product line of NXP). - New subdriver for Marvell MV98DX1135. Driver improvements: - The Bitmain BM1880 driver now supports pin config in addition to muxing. - The Qualcomm drivers can now reserve some GPIOs as taken aside and not usable for users. This is used in ACPI systems to take out some GPIO lines used by the BIOS so that noone else (neither kernel nor userspace) will play with them by mistake and crash the machine. - A slew of refurbishing around the Aspeed drivers (board management controllers for servers) in preparation for the new Aspeed AST2600 SoC. - A slew of improvements over the SH PFC drivers as usual. - Misc cleanups and fixes" * tag 'pinctrl-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (106 commits) pinctrl: aspeed: Strip moved macros and structs from private header pinctrl: aspeed: Fix missed include pinctrl: baytrail: Use GENMASK() consistently pinctrl: baytrail: Re-use data structures from pinctrl-intel.h pinctrl: baytrail: Use defined macro instead of magic in byt_get_gpio_mux() pinctrl: qcom: Add SM8150 pinctrl driver dt-bindings: pinctrl: qcom: Add SM8150 pinctrl binding dt-bindings: pinctrl: qcom: Document missing gpio nodes pinctrl: aspeed: Add implementation-related documentation pinctrl: aspeed: Split out pinmux from general pinctrl pinctrl: aspeed: Clarify comment about strapping W1C pinctrl: aspeed: Correct comment that is no longer true MAINTAINERS: Add entry for ASPEED pinctrl drivers dt-bindings: pinctrl: aspeed: Convert AST2500 bindings to json-schema dt-bindings: pinctrl: aspeed: Convert AST2400 bindings to json-schema dt-bindings: pinctrl: aspeed: Split bindings document in two pinctrl: qcom: Add irq_enable callback for msm gpio pinctrl: madera: Fixup SPDX headers pinctrl: qcom: sdm845: Fix CONFIG preprocessor guard pinctrl: tegra: Add bitmask support for parked bits ...

2017-02-13pinctrl: mvebu: make bool drivers explicitly non-modularPaul Gortmaker1-7/+1
None of the Kconfigs for any of these drivers are tristate, meaning that they currently are not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the drivers there is no doubt they are builtin-only. All drivers get the exact same change, so they are handled in batch. Changes are (1) use builtin_platform_driver, (2) dont use module.h (3) delete module_exit related code, (4) delete MODULE_DEVICE_TABLE, and (5) delete MODULE_LICENCE/MODULE_AUTHOR and associated tags. For the dove driver we explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. We deleted the MODULE_LICENSE etc. tags since all that information is already contained at the top of the file in the comments.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers.

2012-11-11pinctrl: mvebu: move to its own directoryThomas Petazzoni1-0/+472
Like the spear platform, the mvebu platform has multiple files: one core file, and then one file per SoC family. More files will be added later, as support for mach-orion5x and mach-mv78xx0 SoCs is added to pinctrl-mvebu. For those reasons, having a separate subdirectory, drivers/pinctrl/mvebu/ makes sense, and it had already been suggested by Linus Wallej when the driver was originally submitted.
