pinctrl: ultrarisc: Add UltraRISC DP1000 pinctrl driver

2026-06-11T13:02:35+00:00

Add support for the pin controller on the UltraRISC DP1000 SoC. The controller provides mux selection for pins in ports A, B, C, D, and LPC. Ports A-D default to GPIO and support peripheral muxing. LPC pins can be switched to eSPI, but are not available as GPIOs. Basic pin configuration controls such as drive strength, pull-up, and pull-down are also supported.

pinctrl: PINCTRL_STMFX should depend on CONFIG_OF

2026-06-08T22:48:12+00:00

Commit e785c990adcc ("pinctrl: Kconfig: drop unneeded dependencies on OF_GPIO") removed a redundant dependecy on CONFIG_OF_GPIO for several pinctrl drivers, but this change also removed a dependency on CONFIG_OF for some of those drivers. Normally, this wouldn't be a problem, but PINCTRL_STMFX also selected MFD_STMFX, which does depend on CONFIG_OF. This conflict allows MFD_STMFX to be enabled even if CONFIG_OF is disabled. Fix this by also having PINCTRL_STMFX depend on CONFIG_OF. This is okay because the pinctrl-stmfx driver actually does depend on CONFIG_OF functions.

pinctrl: Move Airoha driver to dedicated directory

2026-06-08T08:15:16+00:00

In preparation for additional SoC support, move the Airoha pinctrl driver for AN7581 SoC to a dedicated directory. This is to tidy things up and keep code organized without polluting the Mediatek driver directory. The driver doesn't depend on any generic or common code from the Mediatek codebase so it can be safely moved without any modification.

pinctrl: Add OF dependency for PINCTRL_GENERIC_MUX

2026-05-23T09:02:28+00:00

Add an explicit OF dependency for PINCTRL_GENERIC_MUX to ensure the generic mux support is only enabled when device tree is available. Also fix the stub implementation of pinctrl_generic_to_map() by correcting its last argument to match the non-stub prototype.

pinctrl: add generic board-level pinctrl driver using mux framework

2026-05-05T12:48:55+00:00

Many boards use on-board mux chips (often controlled by GPIOs from an I2C expander) to switch shared signals between peripherals. Add a generic pinctrl driver built on top of the mux framework to centralize mux handling and avoid probe ordering issues. Keep board-level routing out of individual drivers and supports boot-time only mux selection. Ensure correct probe ordering, especially when the GPIO expander is probed later.

pinctrl: Kconfig: drop unneeded dependencies on OF_GPIO

2026-03-10T09:10:50+00:00

OF_GPIO is selected automatically on all OF systems. Any symbols it controls also provide stubs so there's really no reason to select it explicitly. Signed-off-by: Bartosz Golaszewski Signed-off-by: Linus Walleij

pinctrl: eyeq5: Add Mobileye EyeQ6Lplus OLB

2026-03-02T09:17:03+00:00

Add the match data for the pinctrl found in the EyeQ6Lplus OLB. The pin control is identical in function to the one present in the EyeQ5 but has a single bank of 32 pins. Signed-off-by: Benoît Monin Signed-off-by: Linus Walleij

pinctrl: pic32: allow driver to be compiled with COMPILE_TEST

2026-02-24T09:25:19+00:00

This driver currently only supports builds against a PIC32 target. Now that commit b8694faa1a0f ("pinctrl: pic32: update include to use pic32.h from platform_data") is merged, it's possible to compile this driver on other architectures. To avoid future breakage of this driver in the future, let's update the Kconfig so that it can be built with COMPILE_TEST enabled on all architectures.

pinctrl: fix kismet issues with GENERIC_PINCTRL

2026-02-02T23:56:53+00:00

lkp reported that GENERIC_PINCTRL can be select when its dependencies are not. Swap the "depends on" out for "select", as is used in other parts of the pinctrl core that are expected to be selected by drivers.

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.
