Revert "pinctrl-amd: enable IRQ for WACF2200 touchscreen on Lenovo Yoga 7 14AGP11"

2026-05-29T22:00:33+00:00

This reverts commit 3812a9e84265a5cdd90d29fe8d97a023e91fb945. The probe ordering fix in the following patch ensures amd_gpio_probe() completes before i2c-designware probes AMDI0010:02, allowing the existing amd_gpio_irq_enable() flow to work correctly. The manual IRQ restoration added by this patch is therefore no longer needed.

pinctrl-amd: enable IRQ for WACF2200 touchscreen on Lenovo Yoga 7 14AGP11

2026-05-13T07:34:55+00:00

On Lenovo Yoga 7 14AGP11 (83TD), the WACF2200 touchscreen controller is wired via I2C2 (AMDI0010:02) with its interrupt on GPIO pin 157 (confirmed via ACPI _CRS GpioInt decode). After amd_gpio_irq_init() clears all GPIO interrupts at boot, pin 157 is never re-enabled, preventing the touchscreen from signalling the driver. Windows keeps GPIO 157 INTERRUPT_ENABLE (bit 11) and INTERRUPT_MASK (bit 12) set after initialisation. Add a DMI quirk to restore these bits after amd_gpio_irq_init() on this hardware.

pinctrl: amd: Add PM debugging message for turning on/off wakes

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

The GPIOs for devices not in _AEI/_EVT such as touchpad or touchscreen won't have wakeup turned on until the suspend sequence starts. Due to code in amd_gpio_suspend_hibernate_common() masking the interrupt can make this difficult to follow what's going on. Add an explicit debugging message to tell when that was turned on/off.

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. Signed-off-by: Bartosz Golaszewski

pinctrl: amd: Clear GPIO debounce for suspend

2025-07-03T22:24:45+00:00

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: amd: Constify pointers to 'pinctrl_desc'

2025-06-18T11:26:35+00:00

Internal functions obtaining pointers to 'struct pinctrl_desc' do not modify the contents so they can be made pointers to const. This makes code safer, explicit and later allows constifying 'pinctrl_desc' in pinctrl core code.
