pinctrl: airoha: Fix return value in pinconf callbacks

2025-08-22T13:08:58+00:00

Pinctrl stack requires ENOTSUPP error code if the parameter is not
supported by the pinctrl driver. Fix the returned error code in pinconf
callbacks if the operation is not supported.

pinctrl: STMFX: add missing HAS_IOMEM dependency

2025-08-22T06:34:30+00:00

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]

pinctrl: meson: Fix typo in device table macro

2025-08-18T09:10:47+00:00

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

2025-08-07T08:07:06+00:00

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.

Pull pin control updates from Linus Walleij:
 "Nothing stands out, apart from maybe the interesting Eswin EIC7700, a
  RISC-V SoC I've never seen before.

  Core changes:

   - Open code PINCTRL_FUNCTION_DESC() instead of defining a complex
     macro only used in one place

   - Add pinmux_generic_add_pinfunction() helper and use this in a few
     drivers

  New drivers:

   - Amlogic S7, S7D and S6 pin control support

   - Eswin EIC7700 pin control support

   - Qualcomm PMIV0104, PM7550 and Milos pin control support

     Because of unhelpful numbering schemes, the Qualcomm driver now
     needs to start to rely on SoC codenames

   - STM32 HDP pin control support

   - Mediatek MT8189 pin control support

  Improvements:

   - Switch remaining pin control drivers over to the new GPIO set
     callback that provides a return value

   - Support RSVD (reserved) pins in the STM32 driver

   - Move many fixed assignments over to pinctrl_desc definitions

   - Handle multiple TLMM regions in the Qualcomm driver"

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"
