gpiolib: add get_config() and gpiochip_generic_get_config()

2026-09-21T09:14:49Z

A chip with a pin control backend sets a line's configuration through set_config() and gpiochip_generic_config(), but has no way to read one back. gpio-mmio needs that to learn the direction of a line whose direction lives in the pin controller. Add the optional get_config() callback, taking the packed parameter to query and returning its bare argument the way pinctrl_gpio_get_config() does, and gpiochip_generic_get_config() as the pin control backed implementation, the mirror of gpiochip_generic_config(): a chip without pin ranges, or a kernel without pinctrl, gets -ENOTSUPP. Nothing in gpiolib calls get_config() and there is no consumer API; it is for the chip's own use.

gpio: regmap: Add optional runtime PM support

2026-09-16T09:08:26Z

Some gpio-regmap consumers share their regmap with a parent device that may be runtime suspended. GPIO register accesses must resume that device first. Add an optional pm_dev field and acquire it before register translation or access. Release it using runtime autosuspend after each operation. Keep the device active across the complete direction-output sequence and propagate failure when setting the initial output value.

gpio: regmap: Add IRQ enable/disable helpers

2026-07-30T09:05:07Z

Add gpio_regmap_enable_irq() and gpio_regmap_disable_irq(). Since struct gpio_regmap is opaque, drivers cannot access the embedded gpio_chip directly.

gpio: regmap: Add set_config callback

Add a new set_config callback to allow drivers to implement hardware-specific configuration such as debounce settings, or other platform-specific GPIO properties.

gpio: regmap: Add value_xlate callback

2026-07-30T09:05:07Z

Introduce a new optional 'value_xlate' callback. This routine allows drivers to translate or modify the register value and mask immediately before a write operation. It is particularly useful for hardware that requires additional control bits, such as a write-enable bit, to be appended to the data dynamically.

gpio: regmap: Add gpio_regmap_operation to extend reg_mask_xlate callback

2026-07-30T09:05:06Z

Extend the reg_mask_xlate callback with an operation type parameter (enum gpio_regmap_operation) to allow drivers to return different register/mask combinations depending on the specific GPIO operation. Consequently, update all existing drivers utilizing the gpio-regmap framework (across drivers/gpio, drivers/iio, and drivers/pinctrl) to accommodate the new reg_mask_xlate function signature.

gpio: regmap: Provide default IRQ resource request and release callbacks

2026-07-30T09:05:05Z

When GPIO regmap based driver supplies its own IRQ domain, it might still want to keep track of the IRQ requests and releases, in particular to prevent a GPIO, which is used and locked as IRQ, to be requested via standard ways. Provide default callbacks for such cases and keep struct gpio_chip private to GPIO regmap implementation.

The GPIO_LOOKUP_SINGLE() macro defines a lookup table with a single entry followed by an empty sentinel entry. The sentinel entry has a trailing comma which is unnecessary. Remove it.
