pinctrl: bm1880: add missing select GENERIC_PINCONF

2026-07-25T09:33:32+00:00

drivers/pinctrl/pinctrl-bm1880.c initialises its pinconf_ops with
.is_generic = true, but that field is only present when
CONFIG_GENERIC_PINCONF is enabled (guarded by #ifdef in pinconf.h).
The Kconfig entry for PINCTRL_BM1880 never selects GENERIC_PINCONF,
so any config that enables CONFIG_PINCTRL_BM1880=y without
CONFIG_GENERIC_PINCONF=y fails to compile:

  drivers/pinctrl/pinctrl-bm1880.c:1288:10: error: 'const struct pinconf_ops' has no member named 'is_generic'

Found by randconfig testing on arm64; tinyconfig reproducer below.
Add the missing select to fix the build.

pinctrl: microchip-sgpio: add missing select REGMAP_MMIO

2026-07-25T09:21:28+00:00

The driver calls ocelot_regmap_from_resource() via ,
which internally uses devm_regmap_init_mmio() and requires REGMAP_MMIO.
The Kconfig entry does not select REGMAP_MMIO, causing a build failure
when no other driver in the config happens to pull in REGMAP_MMIO:

  include/linux/mfd/ocelot.h:34:24: error: implicit declaration of function 'devm_regmap_init_mmio'

Found by randconfig testing on arm64; tinyconfig reproducer below.

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.

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.
