pinctrl: introduce pinctrl_gpio_get_config()

2026-03-24T12:50:30+00:00

This is a counterpart of pinctrl_gpio_set_config(), which will be used to implement the ->get() interface in a GPIO driver for SCMI. This also requires that we create a stub so pin_config_get_for_pin() can build when CONFIG_PINCONF is disabled.

pinctrl: add generic functions + pins mapper

2026-01-21T12:13:37+00:00

Add a generic function to allow creation of groups and functions at runtime based on devicetree content, before setting up mux mappings. It works similarly to pinconf_generic_dt_node_to_map(), and therefore parses pinconf properties and maps those too, allowing it to be used as the dt_node_to_map member of the pinctrl_ops struct.

pinctrl: add stubs for OF-specific pinconf functions

Allow building drivers using these interfaces with COMPILE_TEST enabled and OF disabled by providing stub definitions.

pinctrl: pinconf-generic: Add API for pinmux propertity in DTS file

2025-02-27T23:03:17+00:00

When describing pin mux func through pinmux propertity, a standard API is added for support. The pinmux contains pin identification and mux values, which can include multiple pins. And groups configuration use other word. DTS such as: func-name { group_alias: group-name{ pinmux= , ; bias-pull-up; drive-strength-microamp = <4000>; }; }; Signed-off-by: Xianwei Zhao Link: https://lore.kernel.org/20250212-amlogic-pinctrl-v5-2-282bc2516804@amlogic.com Signed-off-by: Linus Walleij

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 configuration of pins from gpiolib based drivers

2017-01-26T14:23:01+00:00

When a GPIO driver is backed by a pinctrl driver the GPIO driver sometimes needs to call the pinctrl driver to configure certain things, like whether the pin is used as input or output. In addition to this there are other configurations applicable to GPIOs such as setting debounce time of the GPIO. To support this we introduce a new function pinctrl_gpio_set_config() that can be used by gpiolib based driver to pass configuration requests to the backing pinctrl driver.

pinctrl: pinconf-generic: Allow driver to specify DT params

2015-01-11T21:32:19+00:00

Additionally to the generic DT parameters, allow drivers to provide driver-specific DT parameters to be used with the generic parser infrastructure. To achieve this 'struct pinctrl_desc' is extended to pass custom pinconf option to the core. In order to pass this kind of information, the related data structures - 'struct pinconf_generic_dt_params', 'pin_config_item' - are moved from pinconf internals to the pinconf-generic header. Additionally pinconfg-generic is refactored to not only iterate over the generic pinconf parameters but also take the parameters into account that are provided through the driver's 'struct pinctrl_desc'. In particular 'pinconf_generic_parse_dt_config()' and 'pinconf_generic_dump' helpers are split into two parts each. In order to have a more generic helper that can be used to process the generic parameters as well as the driver-specific ones. v2: - fix typo - add missing documentation for @conf_items member in struct - rebase to pinctrl/devel: conflict in abx500 - rename _pinconf_generic_dump() to pinconf_generic_dump_one() - removed '_' from _parse_dt_cfg() - removed BUG_ONs, error condition is handled in if statements - removed pinconf_generic_dump_group() & pinconf_generic_dump_pin helpers - fixed up corresponding call sites - renamed pinconf_generic_dump() to pinconf_generic_dump_pins() - added kernel-doc to pinconf_generic_dump_pins() - add kernel-doc - more verbose commit message Signed-off-by: Soren Brinkmann Tested-by: Andreas FÃ¤rber Signed-off-by: Linus Walleij
