Merge tag 'pinctrl-v6.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

2025-05-30T16:46:28+00:00

Pull pin control updates from Linus Walleij:
 "An especially linear and sparse improvement and new drivers release.
  Nothing exciting. The biggest change in Bartosz changes to make
  gpiochip set/get calls return error codes (something we should have
  fixed ages ago but is now finally getting fixed.)

  Core changes:

   - Add the devres devm_pinctrl_register_mappings() call that can
     register some pin control machine mappings and have them go away
     with the associated device

  New drivers:

   - Support for the Mediatek MT6893 and MT8196 SoCs

   - Support for the Renesas RZ/V2N SoC

   - Support for the NXP Freescale i.MX943 SoC

  Improvements:

   - Per-SoC suspend/resume callbacks in the Samsung drivers

   - Set all pins as input (High-Z) at probe in the MCP23S08 driver

   - Switch most GPIO chips to use the setters/getters with a return
     value

   - EGPIO support in the Qualcomm QCM2290 driver

   - Fix up the number of available GPIO lines in Qualcomm QCS8300 and
     QCS615"

pinctrl: freescale: Add support for imx943 pinctrl

2025-05-21T08:12:14+00:00

The i.MX943 System Manager (SM) firmware supports the System Control
Management Interface (SCMI) pinctrl protocol, similar to the i.MX95 SM.
The base offset for the i.MX943 IOMUXC Daisy input register differs from
that of the i.MX95. Update the pinctrl-imx-scmi driver to add support for
i.MX943.

pinctrl: freescale: Enable driver if platform is enabled.

2025-05-20T21:39:52+00:00

The pinctrl drivers are not enabled in defconfig. Instead of listing
each driver in the defconfig, enable then by default if the platform/soc
support is enabled as well.

pinctrl: freescale: Depend imx-scu driver on OF

2025-05-20T21:39:52+00:00

Although the driver itself does not depend on OF itself, it selects
PINCTRL_IMX which depends on OF. So only select PINCTRL_IMX if OF is
already selected to ensure dependencies are met.

pinctrl: imx: Return NULL if no group is matched and found

2025-04-15T07:42:15+00:00

Currently if no group is matched and found, this function will return
the last grp to the caller, this is not expected, it is supposed to
return NULL in this case.

pinctrl: Use of_property_present() for non-boolean properties

2024-11-08T08:02:15+00:00

The use of of_property_read_bool() for non-boolean properties is
deprecated in favor of of_property_present() when testing for property
presence.

pinctrl: imx-scmi: Drop obsolete dependency on COMPILE_TEST

2024-10-23T09:51:34+00:00

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), OF
can be enabled on all architectures. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

As ARM_SCMI_PROTOCOL already depends on COMPILE_TEST, we also don't
need to add COMPILE_TEST as an alternative dependency for it.

pinctrl: imx27: Fix too generic defines

2024-10-04T07:45:45+00:00

The "PC" define is colliding with the (apparently broadcased)
define for "program counter" on Loongarch, so let's rename all
these 2-letter defines so they don't collide with stuff.

When PINCTRL_IMX_SCU was selected by PINCTRL_IMX8DXL or PINCTRL_IMX8QM
combined with COMPILE_TEST on a non-arm platforms, the IMX_SCU
dependency could not be enabled.
