pinctrl: aw9523: fix can_sleep flag for GPIO chip

2025-07-04T08:31:50Z

The GPIO expander is connected via I2C, thus the can_sleep flag has to be set to true. This fixes spurious "scheduling while atomic" bugs in the kernel ringbuffer.

pinctrl: amd: Clear GPIO debounce for suspend

2025-07-03T22:24:45Z

soc-button-array hardcodes a debounce value by means of gpio_keys which uses pinctrl-amd as a backend to program debounce for a GPIO. This hardcoded value doesn't match what the firmware intended to be programmed in _AEI. The hardcoded debounce leads to problems waking from suspend. There isn't appetite to conditionalize the behavior in soc-button-array or gpio-keys so clear it when the system suspends to avoid problems with being able to resume.

pinctrl: nuvoton: Fix boot on ma35dx platforms

2025-06-18T12:29:34Z

As part of a wider cleanup trying to get rid of OF specific APIs, an incorrect (and partially unrelated) cleanup was introduced. The goal was to replace a device_for_each_chil_node() loop including an additional condition inside by a macro doing both the loop and the check on a single line. The snippet: device_for_each_child_node(dev, child) if (fwnode_property_present(child, "gpio-controller")) continue; was replaced by: for_each_gpiochip_node(dev, child) which expands into: device_for_each_child_node(dev, child) for_each_if(fwnode_property_present(child, "gpio-controller")) This change is actually doing the opposite of what was initially expected, breaking the probe of this driver, breaking at the same time the whole boot of Nuvoton platforms (no more console, the kernel WARN()). Revert these two changes to roll back to the correct behavior.

pinctrl: qcom: msm: mark certain pins as invalid for interrupts

2025-06-18T11:56:34Z

On some platforms, the UFS-reset pin has no interrupt logic in TLMM but is nevertheless registered as a GPIO in the kernel. This enables the user-space to trigger a BUG() in the pinctrl-msm driver by running, for example: `gpiomon -c 0 113` on RB2. The exact culprit is requesting pins whose intr_detection_width setting is not 1 or 2 for interrupts. This hits a BUG() in msm_gpio_irq_set_type(). Potentially crashing the kernel due to an invalid request from user-space is not optimal, so let's go through the pins and mark those that would fail the check as invalid for the irq chip as we should not even register them as available irqs. This function can be extended if we determine that there are more corner-cases like this.

pinctrl: sunxi: dt: Consider pin base when calculating bank number from pin

2025-06-10T12:35:40Z

In prepare_function_table() when the pinctrl function table IRQ entries are generated, the pin bank is calculated from the absolute pin number; however the IRQ bank mux array is indexed from the first pin bank of the controller. For R_PIO controllers, this means the absolute pin bank is way off from the relative pin bank used for array indexing. Correct this by taking into account the pin base of the controller.

pinctrl: tb10x: Drop of_match_ptr for ID table

2025-06-09T08:16:46Z

The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it might not be relevant here).
