gpio: regmap: Add IRQ enable/disable helpers

2026-07-30T09:05:07+00:00

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

2026-07-30T09:05:07+00:00

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

2026-07-30T09:05:07+00:00

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

2026-07-30T09:05:06+00:00

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

2026-07-30T09:05:05+00:00

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.

gpiolib: remove trailing comma from sentinel in GPIO_LOOKUP_SINGLE

2026-07-15T07:37:38+00:00

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.

gpio: nomadik: remove dead DB8540 code from

2026-06-11T08:26:40+00:00

DB8540 support was removed in commit b6d09f780761 ("pinctrl: nomadik:
Drop U8540/9540 support"), but a couple small pieces of related code
remained in . Remove them.

Discovered while searching for CONFIG_* symbols referenced in code but
not defined in any Kconfig file.

gpio: regmap: Support sparsed fixed direction

2026-05-12T09:54:17+00:00

On some regmapped GPIOs apparently only a sparser selection of the lines
(not all) are actually fixed direction.

Support this situation by adding an optional bitmap indicating which
GPIOs are actually fixed direction and which are not.
