pinctrl: bm1880: add missing select GENERIC_PINCONF

2026-08-09T18:21:50+00:00

commit dad6e107b3cd9d20514e7799b7ad8674f81e3f30 upstream. 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

2026-08-09T18:21:50+00:00

commit 25cb6e9a13123d1039cdc75b446ac52e1ebdc26d upstream. 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: STMFX: add missing HAS_IOMEM dependency

2025-09-04T13:30:18+00:00

[ Upstream commit a12946bef0407cf2db0899c83d42c47c00af3fbc ] When building on ARCH=um (which does not set HAS_IOMEM), kconfig reports an unmet dependency caused by PINCTRL_STMFX. It selects MFD_STMFX, which depends on HAS_IOMEM. To stop this warning, PINCTRL_STMFX should also depend on HAS_IOMEM. kconfig warning: WARNING: unmet direct dependencies detected for MFD_STMFX Depends on [n]: HAS_IOMEM [=n] && I2C [=y] && OF [=y] Selected by [y]: - PINCTRL_STMFX [=y] && PINCTRL [=y] && I2C [=y] && OF_GPIO [=y] Fixes: 1490d9f841b1 ("pinctrl: Add STMFX GPIO expander Pinctrl/GPIO driver") Signed-off-by: Randy Dunlap Link: https://lore.kernel.org/20250815022721.1650885-1-rdunlap@infradead.org Signed-off-by: Linus Walleij Signed-off-by: Sasha Levin

pinctrl: pinctrl-oxnas: remove obsolete pinctrl driver

2023-08-15T09:06:32+00:00

Due to lack of maintenance and stall of development for a few years now, and since no new features will ever be added upstream, remove support for OX810 and OX820 pinctrl & gpio.

pinctrl: mlxbf3: remove broken Kconfig 'select'

2023-06-19T08:51:20+00:00

The new pinctrl driver selects GPIO_MLXBF3, but that can not be enabled yet because the MELLANOX_PLATFORM symbol does not exist in the tree: WARNING: unmet direct dependencies detected for GPIO_MLXBF3 Depends on [n]: GPIOLIB [=y] && PCI [=n] && (MELLANOX_PLATFORM [=n] && ARM64 [=y] || COMPILE_TEST [=y]) Selected by [y]: - PINCTRL_MLXBF3 [=y] && PINCTRL [=y] && (MELLANOX_PLATFORM [=n] && ARM64 [=y] || COMPILE_TEST [=y]) As it turns out, the pinctlr driver still builds fine without this, so just remove the select statement.
