pinctrl: make struct pinfunction a pointer in struct function_desc

2025-09-08T12:22:41+00:00

We currently duplicate the entire struct pinfunction object in pinmux_generic_add_pinfunction(). While this is inevitable when the arguments come in split through pinmux_generic_add_function(), users of pinmux_generic_add_pinfunction() will typically pass addresses of structures in .rodata, meaning we can try to avoid the duplication with the help from kmemdup_const(). To that end: don't wrap the entire struct pinfunction in struct function_desc but rather just store the address.

pinctrl: constify pinmux_generic_get_function()

2025-09-08T12:22:33+00:00

With all users of struct function_desc limited to only accessing it using the dedicated function and never modifying it, we can now constify the return value of pinmux_generic_get_function() treewide.

pinctrl: imx: don't access the pin function radix tree directly

2025-09-08T12:22:08+00:00

The radix tree containing pin function descriptors should not be accessed directly by drivers. There are dedicated functions for it. I suppose this driver does it so that the memory containing the function description is not duplicated but we're going to address that shortly so convert it to using generic pinctrl APIs.

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" * tag 'pinctrl-v6.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (82 commits) pinctrl: freescale: Add support for imx943 pinctrl pinctrl: core: add devm_pinctrl_register_mappings() pinctrl: remove extern specifier for functions in machine.h pinctrl: mediatek: eint: Fix invalid pointer dereference for v1 platforms pinctrl: freescale: Enable driver if platform is enabled. pinctrl: freescale: Depend imx-scu driver on OF pinctrl: armada-37xx: propagate error from armada_37xx_pmx_set_by_name() pinctrl: armada-37xx: propagate error from armada_37xx_gpio_get_direction() pinctrl: armada-37xx: propagate error from armada_37xx_pmx_gpio_set_direction() pinctrl: armada-37xx: propagate error from armada_37xx_gpio_get() pinctrl: armada-37xx: propagate error from armada_37xx_gpio_direction_output() pinctrl: armada-37xx: set GPIO output value before setting direction pinctrl: armada-37xx: use correct OUTPUT_VAL register for GPIOs > 31 pinctrl: meson: Drop unused aml_pctl_find_group_by_name() pinctrl: at91: Fix possible out-of-boundary access pinctrl: add stubs for OF-specific pinconf functions pinctrl: qcom: correct the ngpios entry for QCS8300 pinctrl: qcom: correct the ngpios entry for QCS615 dt-bindings: pinctrl: qcom: correct gpio-ranges in examples for qcs8300 dt-bindings: pinctrl: qcom: correct gpio-ranges in examples for 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.

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.

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.

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: 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.
