There is an irqd_to_hwirq() intended to get the hwirq number. Switch all use to it. Suggested-by: Andy Shevchenko Signed-off-by: Mario Limonciello (AMD) Reviewed-by: Andy Shevchenko Link: https://lore.kernel.org/20250821144942.2463014-1-superm1@kernel.org Signed-off-by: Linus Walleij

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.

pinctrl: amd: Fix hibernation support with CONFIG_SUSPEND unset

2025-05-13T11:45:19+00:00

After recent changes, pinctrl-amd will not support hibernation when CONFIG_HIBERNATION is set and CONFIG_SUSPEND isn't because it will not register amd_gpio_pm_ops then. Address this by restoring dependencies on CONFIG_PM_SLEEP where necessary for hibernation support. Signed-off-by: Rafael J.

pinctrl: amd: Fix use of undeclared identifier 'pinctrl_amd_s2idle_dev_ops'

2025-05-06T13:54:05+00:00

`pinctrl_amd_s2idle_dev_ops` is hidden under both `CONFIG_ACPI` and `CONFIG_PM_SLEEP` so the functions that use it need the same scope. Adjust checks to look for both, and while updating make it CONFIG_SUSPEND instead as that's what the ACPI header uses.
