Pull gpio updates from Bartosz Golaszewski:
 "GPIO core:
   - extend the gpio-regmap abstraction layer with more features
     allowing users to override configuration setting, translate
     register values and masks and enable/disable interrupts
   - extend GPIO kunit tests with suites verifying probe ordering by
     software node devlink support and software node hogs
   - shrink GPIO kunit initialization code
   - coding style updates (remove commas from sentinels where
     applicable)
   - with all users now converted treewide to using real firmware node
     links for software node GPIO lookup: remove the deprecated
     label-matching mechanism from from GPIO core
   - drop redundant return value check of nonseekable_open() in
     gpiolib-cdev
   - use IRQ trigger helpers where applicable

  Driver updates:
   - refactor error paths and logging in gpio-nomadik
   - use more modern interfaces for getting resources in gpio-rockchip,
     gpio-bt8xx and gpio-pca9570
   - add missing MODULE_DEVICE_TABLE() to gpio-sifive and gpio-vf610
   - drop unused FILONOFF macro from gpio-rcar
   - extend build coverage of ioport GPIO drivers with COMPILE_TEST=y
   - only enable the gpio-rtd driver by default with ARCH_REALTEK=y to
     avoid bloating the build
   - refactor coding style in several drivers
   - use correct endianess translation in gpio-pcf85x
   - add wake-up interrupt support to gpio-mvebu
   - apply initial value in direction output setter in gpio-by-pinctrl

  Misc:
   - replace linux/gpio.h inclusions treewide with linux/gpio/legacy.h
     which now exports all the deprecated APIs
   - select GPIOLIB_LEGACY in Kconfig where required treewide
   - use software nodes for gpio-keys in MFD drivers

  Devicetree bindings:
   - describe the realtek rtd1625 GPIO controller
   - document new models for gpio-pca95xx and gpio-cadence
   - document new property in gpio-rockchip"

dt-bindings: gpio: rockchip,gpio-bank: Add rockchip,grf property

2026-08-10T11:37:55+00:00

Some Rockchip SoCs, such as the RV1106, give each GPIO bank its own
IO control (IOC) register block rather than grouping the registers of
all banks into a shared GRF region. Add an optional rockchip,grf
property to the gpio-bank binding so that each bank node can reference
the syscon for its own IOC block.

dt-bindings: Correct white-space style

2026-08-07T14:38:48+00:00

Correct a few white-space issues, like double space after '=' or before
bracket '{' characters, which will be flagged by dt-check-style.  No
functional changes.

dt-bindings: soc: fsl: qe: Add support of IRQ in QE GPIO

2026-08-03T12:58:59+00:00

Some QE GPIO pins have an associated interrupt line in the QE PIC to
signal state changes on the pin.  Add the corresponding
interrupt-controller / nexus properties to the QE GPIO binding.

Because the GPIO controller does not perform any interrupt handling
itself, a nexus node (interrupt-map) is used to map each GPIO line
supporting IRQ to the parent QE PIC interrupt domain.

As the QE PIC can be configured to generate an interrupt on either a
high-to-low transition or any change in signal state, three
interrupt-map entries are needed per GPIO pin that can yield an
interrupt (falling, both, and the "none" case which defaults to both in
QE PIC).  This overhead is necessary because the interrupt-map-pass-thru
property is not part of the DT specification.

The interrupt-map property is optional: it is not required for GPIO
banks that have no interrupt capable GPIO line (e.g. port D on MPC8323),
or when interrupt functionality is not used.

Update the example to show a scenario where each bank supports a
different numbers of IRQs, or no IRQs at all.

dt-bindings: soc: fsl: qe: Convert QE GPIO to DT schema

2026-08-03T12:58:58+00:00

Convert QE GPIO devicetree binding to DT schema. The old binding uses
fsl,-qe-pario-bank because multiple MCP83XX SoC has support for
these GPIO banks. The best practice is to list out every  instead.

The Kinetic Technologies KTS1622 is a 16-bit general-purpose I/O
expander via the I2C bus for microcontrollers when additional I/Os
are needed while keeping interconnections to the minimum. Datasheet
comparison suggests that it is compatible with TCAL6416, add the
compatible string and TCAL6416 as a fallback compatible.

Add the device tree bindings for the Realtek DHC (Digital Home Center)
RTD1625 GPIO controllers.

The RTD1625 GPIO controller features a per-pin register architecture
that differs significantly from previous generations. It utilizes
separate register blocks for GPIO configuration and interrupt control.

dt-bindings: gpio: Add Tegra238 support

2026-05-18T09:12:01+00:00

Extend the existing Tegra186 GPIO controller device tree bindings with
support for the GPIO controllers found on Tegra238. Tegra238 has two
GPIO controllers: the main controller and always-on (AON) controller.
The number of pins is slightly different, but the programming model
remains the same.

Add a new header, include/dt-bindings/gpio/nvidia,tegra238-gpio.h,
that defines port IDs as well as the TEGRA238_MAIN_GPIO() helper,
both of which are used in conjunction to create a unique specifier
for each pin.
