pinctrl: cirrus: cs42l43: Fix double-put in cs42l43_pin_probe()

2026-03-25T10:05:38+00:00

[ Upstream commit fd5bed798f45eb3a178ad527b43ab92705faaf8a ] devm_add_action_or_reset() already invokes the action on failure, so the explicit put causes a double-put.

pinctrl: cirrus: Fix fwnode leak in cs42l43_pin_probe()

2025-12-01T10:41:45+00:00

[ Upstream commit 9b07cdf86a0b90556f5b68a6b20b35833b558df3 ] The driver calls fwnode_get_named_child_node() which takes a reference on the child node, but never releases it, which causes a reference leak. Fix by using devm_add_action_or_reset() to automatically release the reference when the device is removed.

pinctrl: lochnagar: Don't build on MIPS

2024-01-20T10:51:37+00:00

[ Upstream commit 6588732445ff19f6183f0fa72ddedf67e5a5be32 ] MIPS appears to define a RST symbol at a high level, which clashes with some register naming in the driver. Since there is currently no case for running this driver on MIPS devices simply cut off the build of this driver on MIPS.

pinctrl: cs42l43: Add support for the cs42l43

2023-08-17T11:06:11+00:00

The CS42L43 is an audio CODEC with integrated MIPI SoundWire interface (Version 1.2.1 compliant), I2C, SPI, and I2S/TDM interfaces designed for portable applications. It provides a high dynamic range, stereo DAC for headphone output, two integrated Class D amplifiers for loudspeakers, and two ADCs for wired headset microphone input or stereo line input. PDM inputs are provided for digital microphones. Add a basic pinctrl driver which supports driver strength for the various pins, gpios, and pinmux for the 2 multi-function pins.

pinctrl: Propagate firmware node from a parent device

2021-12-22T02:09:56+00:00

When creating MFD platform devices the firmware node is left unset. This, in particular, prevents GPIO library to use it for different purposes. Propagate firmware node from the parent device and let GPIO library do the right thing. While at it, slightly modify the headers to reflect the usage of APIs.

pinctrl: Get rid of duplicate of_node assignment in the drivers

2021-12-16T03:18:30+00:00

GPIO library does copy the of_node from the parent device of the GPIO chip, there is no need to repeat this in the individual drivers. Remove these assignment all at once. For the details one may look into the of_gpio_dev_init() implementation.

pinctrl: madera: Add missing call to pinctrl_unregister_mappings

2020-02-28T23:34:23+00:00

pinctrl_register_mappings is called in the pdata case, however a call to pinctrl_unregister_mappings is missing causing the mappings to be leaked on driver unbind.

Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes, nothing too exciting about this. Some changes hit arch/sh and arch/arm but are well isolated and acknowledged by the respective arch maintainers. Core changes: - Dropped the chained IRQ setup callback into GPIOLIB as we got rid of the last users of that in this changeset. New drivers: - New driver for Ingenic X1830. - New driver for Freescale i.MX8MP. Driver enhancements: - Fix all remaining Intel drivers to pass their IRQ chips along with the GPIO chips. - Intel Baytrail allocates its irqchip dynamically. - Intel Lynxpoint is thoroughly rewritten and modernized. - Aspeed AST2600 pin muxing and configuration is much improved. - Qualcomm SC7180 functions are updated and wakeup interrupt map is provided. - A whole slew of Renesas SH-PFC cleanups and improvements. - Fix up the Intel DT bindings to use the generic YAML DT bindings schema (a first user of this)" * tag 'pinctrl-v5.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (99 commits) pinctrl: madera: Remove extra blank line pinctrl: qcom: Don't lock around irq_set_irq_wake() pinctrl: mvebu: armada-37xx: use use platform api gpio: Drop the chained IRQ handler assign function pinctrl: freescale: Add i.MX8MP pinctrl driver support dt-bindings: imx: Add pinctrl binding doc for i.MX8MP pinctrl: tigerlake: Tiger Lake uses _HID enumeration pinctrl: sunrisepoint: Add Coffee Lake-S ACPI ID pinctrl: iproc: Use platform_get_irq_optional() to avoid error message pinctrl: dt-bindings: Fix some errors in the lgm and pinmux schema pinctrl: intel: Pass irqchip when adding gpiochip pinctrl: intel: Add GPIO <-> pin mapping ranges via callback pinctrl: baytrail: Replace WARN with dev_info_once when setting direct-irq pin to output pinctrl: baytrail: Do not clear IRQ flags on direct-irq enabled pins pinctrl: sunrisepoint: Add missing Interrupt Status register offset pinctrl: sh-pfc: Split R-Car H3 support in two independent drivers pinctrl: artpec6: fix __iomem on reg in set pinctrl: ingenic: Use devm_platform_ioremap_resource() pinctrl: ingenic: Factorize irq_set_type function pinctrl: ingenic: Remove duplicated ingenic_chip_info structures ...
