gpio: regmap: fix memory leak of gpio_regmap structure

2025-09-22T14:35:21Z

The gpio_regmap structure is leaked on the error path. Fix this by jumping to the appropriate kfree instead of returning directly.

gpiolib: Extend software-node support to support secondary software-nodes

2025-09-22T14:23:43Z

When a software-node gets added to a device which already has another fwnode as primary node it will become the secondary fwnode for that device. Currently if a software-node with GPIO properties ends up as the secondary fwnode then gpiod_find_by_fwnode() will fail to find the GPIOs. Add a new gpiod_fwnode_lookup() helper which falls back to calling gpiod_find_by_fwnode() with the secondary fwnode if the GPIO was not found in the primary fwnode.

gpiolib: acpi: initialize acpi_gpio_info struct

2025-09-15T06:55:40Z

Since commit 7c010d463372 ("gpiolib: acpi: Make sure we fill struct acpi_gpio_info"), uninitialized acpi_gpio_info struct are passed to __acpi_find_gpio() and later in the call stack info->quirks is used in acpi_populate_gpio_lookup.

gpio: fix GPIO submenu in Kconfig

Commit a86240a37d43 ("gpiolib: enable CONFIG_GPIOLIB_LEGACY even for !GPIOLIB") accidentally pulled all items from within the GPIOLIB submenu into the main driver menu.

gpio: timberdale: fix off-by-one in IRQ type boundary check

2025-08-26T10:03:09Z

timbgpio_irq_type() currently accepts offset == ngpio, violating gpiolib's [0..ngpio-1] contract. This can lead to undefined behavior when computing '1 << offset', and it is also inconsistent with users that iterate with for_each_set_bit(..., ngpio). Tighten the upper bound to reject offset == ngpio. No functional change for in-range offsets.

gpiolib: acpi: Program debounce when finding GPIO

2025-08-21T09:40:42Z

When soc-button-array looks up the GPIO to use it calls acpi_find_gpio() which will parse _CRS. acpi_find_gpio.cold (drivers/gpio/gpiolib-acpi-core.c:953) gpiod_find_and_request (drivers/gpio/gpiolib.c:4598 drivers/gpio/gpiolib.c:4625) gpiod_get_index (drivers/gpio/gpiolib.c:4877) The GPIO is setup basically, but the debounce information is discarded. The platform will assert what debounce should be in _CRS, so program it at the time it's available. Reviewed-by: Mika Westerberg Signed-off-by: Mario Limonciello (AMD) Signed-off-by: Andy Shevchenko
