pinctrl: airoha: fix wrong MDIO function bitmaks

2025-09-08T21:01:19Z

With further testing with an attached Aeonsemi it was discovered that the pinctrl MDIO function applied the wrong bitmask. The error was probably caused by the confusing documentation related to these bits. Inspecting what the bootloader actually configure, the SGMII_MDIO_MODE is never actually set but instead it's set force enable to the 2 GPIO (gpio 1-2) for MDC and MDIO pin. The usage of GPIO might be confusing but this is just to instruct the SoC to not mess with those 2 PIN and as Benjamin reported it's also an Errata of 7581. The FORCE_GPIO_EN doesn't set them as GPIO function (that is configured by a different register) but it's really to actually ""enable"" those lines. Normally the SoC should autodetect this by HW but it seems AN7581 have problem with this and require this workaround to force enable the 2 pin. Applying this configuration permits correct functionality of any externally attached PHY.

pinctrl: airoha: fix wrong PHY LED mux value for LED1 GPIO46

2025-09-08T13:01:39Z

In all the MUX value for LED1 GPIO46 there is a Copy-Paste error where the MUX value is set to LED0_MODE_MASK instead of LED1_MODE_MASK. This wasn't notice as there were no board that made use of the secondary PHY LED but looking at the internal Documentation the actual value should be LED1_MODE_MASK similar to the other GPIO entry. Fix the wrong value to apply the correct MUX configuration.

pinctrl: airoha: Fix return value in pinconf callbacks

pinctrl: STMFX: add missing HAS_IOMEM dependency

2025-08-22T06:34:30Z

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

pinctrl: meson: Fix typo in device table macro

2025-08-18T09:10:47Z

The typo when using the MODULE_DEVICE_TABLE macro was not noticeable because the macro was defined only if the module was built as a separate module.

treewide: rename GPIO set callbacks back to their original names

2025-08-07T08:07:06Z

The conversion of all GPIO drivers to using the .set_rv() and .set_multiple_rv() callbacks from struct gpio_chip (which - unlike their predecessors - return an integer and allow the controller drivers to indicate failures to users) is now complete and the legacy ones have been removed. Rename the new callbacks back to their original names in one sweeping change. Signed-off-by: Bartosz Golaszewski

Pull SoC driver updates from Arnd Bergmann: "Changes are all over the place, but very little sticks out as noteworthy. There is a new misc driver for the Raspberry Pi 5's RP1 multifunction I/O chip, along with hooking it up to the pinctrl and clk frameworks. The reset controller and memory subsystems have mainly small updates, but there are two new reset drivers for the K230 and VC1800B SoCs, and new memory driver support for Tegra264. The ARM SMCCC and SCMI firmware drivers gain a few more features that should help them be supported across more environments. Similarly, the SoC specific firmware on Tegra and Qualcomm get minor enhancements and chip support. In the drivers/soc/ directory, the ASPEED LPC snoop driver gets an overhaul for code robustness, the Tegra and Qualcomm and NXP drivers grow to support more chips, while the Hisilicon, Mediatek and Renesas drivers see mostly janitorial fixes" * tag 'soc-drivers-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (100 commits) bus: del unnecessary init var soc: fsl: qe: convert set_multiple() to returning an integer pinctrl: rp1: use new GPIO line value setter callbacks soc: hisilicon: kunpeng_hccs: Fix incorrect log information dt-bindings: soc: qcom: qcom,pmic-glink: document Milos compatible dt-bindings: soc: qcom,aoss-qmp: document the Milos Always-On Subsystem side channel dt-bindings: firmware: qcom,scm: document Milos SCM Firmware Interface soc: qcom: socinfo: Add support to retrieve APPSBL build details soc: qcom: pmic_glink: fix OF node leak soc: qcom: spmi-pmic: add more PMIC SUBTYPE IDs soc: qcom: socinfo: Add PM7550 & PMIV0108 PMICs soc: qcom: socinfo: Add SoC IDs for SM7635 family dt-bindings: arm: qcom,ids: Add SoC IDs for SM7635 family firmware: qcom: scm: request the waitqueue irq *after* initializing SCM firmware: qcom: scm: initialize tzmem before marking SCM as available firmware: qcom: scm: take struct device as argument in SHM bridge enable firmware: qcom: scm: remove unused arguments from SHM bridge routines soc: qcom: rpmh-rsc: Add RSC version 4 support memory: tegra: Add Tegra264 MC and EMC support firmware: tegra: bpmp: Fix build failure for tegra264-only config ...
