Wed, 10 Jun 2026 07:29:56 +0200

pinctrl: ultrarisc: Add UltraRISC DP1000 pinctrl driverAdd support for the pin controller on the UltraRISC DP1000 SoC.The controller provides mux selection for pins in ports A, B, C, D, andLPC. Ports A-D default to GPIO and support peripheral muxing. LPC pinscan be switched to eSPI, but are not available as GPIOs. Basic pinconfiguration controls such as drive strength, pull-up, and pull-downare also supported.Signed-off-by: Jia Wang Reviewed-by: Bartosz Golaszewski Signed-off-by: Linus Walleij List of files: /linux/drivers/pinctrl/Kconfig

Tue, 02 Jun 2026 23:11:16 +0200

pinctrl: PINCTRL_STMFX should depend on CONFIG_OFCommit e785c990adcc ("pinctrl: Kconfig: drop unneeded dependencieson OF_GPIO") removed a redundant dependecy on CONFIG_OF_GPIO forseveral pinctrl drivers, but this change also removed a dependencyon CONFIG_OF for some of those drivers.Normally, this wouldn't be a problem, but PINCTRL_STMFX also selectedMFD_STMFX, which does depend on CONFIG_OF. This conflict allowsMFD_STMFX to be enabled even if CONFIG_OF is disabled.Fix this by also having PINCTRL_STMFX depend on CONFIG_OF. This isokay because the pinctrl-stmfx driver actually does depend on CONFIG_OFfunctions.Fixes: e785c990adcc ("pinctrl: Kconfig: drop unneeded dependencies on OF_GPIO")Signed-off-by: Timur Tabi Signed-off-by: Linus Walleij List of files: /linux/drivers/pinctrl/Kconfig

Merge tag 'pinctrl-v6.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrlPull pin control updates from Linus Walleij: "We have GPIO awareness in the pin control core and an interesting AAEON driver. Core changes: - Allow pins to be identified/marked as GPIO mode with a special callback. The pin controller core is now "aware" if a pin is in GPIO mode if the callback is implemented in the driver, and can thus be marked as "strict", i.e. disallowing simultaneous use of a line as GPIO and another function such as I2C. This is enabled in the Qualcomm TLMM driver and also implemeted from day 1 in the new Broadcom STB driver - Rename the pin config option PIN_CONFIG_OUTPUT to PIN_CONFIG_LEVEL to better describe what the config is doing, as well as making it more intuitive what shall be returned when reading this property New drivers: - Qualcomm SDM660 LPASS LPI TLMM pin controller subdriver - Qualcomm Glymur family pin controller driver - Broadcom STB family pin controller driver - Tegra186 pin controller driver - AAEON UP pin controller support. This is some special pin controller that works as an external advanced line MUX and amplifier for signals from an Intel SoC. A cooperative effort with the GPIO maintainer was needed to reach a solution where we reuse code from the GPIO aggregator/forwarder driver - Renesas RZ/T2H and RZ/N2H pin controller support - Axis ARTPEC-8 subdriver for the Samsung pin controller driver Improvements: - Output enable (OEN) support in the Renesas RZG2L driver - Properly support bias pull up/down in the pinctrl-single driver - Move over all GPIO portions using generic MMIO GPIO to the new generic GPIO chip management which has a nice and separate API - Proper DT bindings for some older Broadcom SoCs - External GPIO (EGPIO) support in the Qualcomm SM8250 Deleted code: - Dropped the now unused Samsung S3C24xx drivers"* tag 'pinctrl-v6.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (75 commits) pinctrl: use more common syntax for compound literals pinctrl: Simplify printks with pOF format pinctrl: qcom: Add SDM660 LPASS LPI TLMM dt-bindings: pinctrl: qcom: Add SDM660 LPI pinctrl pinctrl: qcom: lpass-lpi: Add ability to use custom pin offsets pinctrl: qcom: Add glymur pinctrl driver dt-bindings: pinctrl: qcom: Add Glymur pinctrl pinctrl: qcom: sm8250: Add egpio support pinctrl: generic: rename PIN_CONFIG_OUTPUT to LEVEL pinctrl: keembay: fix double free in keembay_build_functions() pinctrl: spacemit: fix typo in PRI_TDI pin name pinctrl: eswin: Fix regulator error check and Kconfig dependency pinctrl: bcm: Add STB family pin controller driver dt-bindings: pinctrl: Add support for Broadcom STB pin controller pinctrl: qcom: make the pinmuxing strict pinctrl: qcom: mark the `gpio` and `egpio` pins function as non-strict functions pinctrl: qcom: add infrastructure for marking pin functions as GPIOs pinctrl: allow to mark pin functions as requestable GPIOs pinctrl: qcom: use generic pin function helpers pinctrl: make struct pinfunction a pointer in struct function_desc ...

pinctrl: eswin: Fix regulator error check and Kconfig dependencySmatch reported the following warning in eic7700_pinctrl_probe(): drivers/pinctrl/pinctrl-eic7700.c:638 eic7700_pinctrl_probe() warn: passing zero to 'PTR_ERR'The root cause is that devm_regulator_get() may return NULL whenCONFIG_REGULATOR is disabled. In such case, IS_ERR_OR_NULL() triggersPTR_ERR(NULL) which evaluates to 0, leading to passing a success codeas an error.However, this driver cannot work without a regulator. To fix this: - Change the check from IS_ERR_OR_NULL() to IS_ERR() - Update Kconfig to explicitly select REGULATOR and REGULATOR_FIXED_VOLTAGE, ensuring that the regulator framework is always available.This resolves the Smatch warning and enforces the correct dependency.Suggested-by: Dan Carpenter Fixes: 5b797bcc00ef ("pinctrl: eswin: Add EIC7700 pinctrl driver")Reported-by: Dan Carpenter Closes: https://lore.kernel.org/linux-gpio/aKRGiZ-fai0bv0tG@stanley.mountain/Signed-off-by: Yulin Lu Signed-off-by: Linus Walleij List of files: /linux/drivers/pinctrl/Kconfig
