+GPIO Drivers
+============
+
+- ``include/nuttx/ioexpander/gpio.h``. All structures and APIs needed
+ to work with GPIO pins as drivers are provided in this header file. This
+ header file includes:
+
+ #. Structures and interface descriptions needed to develop a
+ low-level, board-specific, GPIO driver.
+ #. To register the GPIO driver with a common GPIO character
+ driver.
+ #. Interfaces needed for interfacing user programs with the
+ common GPIO character driver.
+
+- ``drivers/ioexpander/gpio.c``. The implementation of the common GPIO
+ character driver.
+
+Application Programming Interface
+=================================
+
+The Application Programming Interface is included in the application with
+the following header file.
+
+
+.. code-block:: c
+
+ #include <nuttx/ioexpander/gpio.h>
+
+A GPIO pin is either an input pin or an output pin.
+
+One GPIO pin is registered as a POSIX character device file into ``/dev``
+namespace. It is necessary to open the device to get a file descriptor for
+further operations. This can be done with standard POSIX ``open()`` call.
+Only one pir per driver is supported by the peripheral.
+
+Standard POSIX ``read()`` and ``write()`` operations are not allowed for GPIO
+based drivers. All interface is routed through IOCTL calls. Following commands
+are supported:
+
+ * :c:macro:`GPIOC_WRITE`
+ * :c:macro:`GPIOC_READ`
+ * :c:macro:`GPIOC_PINTYPE`
+ * :c:macro:`GPIOC_REGISTER`
+ * :c:macro:`GPIOC_UNREGISTER`
+ * :c:macro:`GPIOC_SETPINTYPE`
+
+
+.. c:macro:: GPIOC_WRITE
+
+The ``GPIOC_WRITE`` command sets the value of an output GPIO. The argument
+is either 0 (set low value) or 1 (set high value). It is possible to write
+to output pins only. Typical use case is:
+
+.. code-block:: c
+
+ bool value = true;
+ int ret = ioctl(fd, GPIOC_WRITE, value);
+
+
+.. c:macro:: GPIOC_READ
+
+The ``GPIOC_READ`` command reads the value of a GPIO. The argument
+is a pointer to a bool value to receive the result. The result is either 0
+(low value) or 1 (high value). It is possible to read from both input and
+output pins. The currently set value is returned in case the pin is output
+pin. Typical use case is:
+
+.. code-block:: c
+
+ bool value;
+ int ret = ioctl(fd, GPIOC_READ, (unsigned long)(uintptr_t)&value);
+
+.. c:macro:: GPIOC_PINTYPE
+
+The ``GPIOC_PINTYPE`` command gets the type of GPIO pin. The argument
+is a pointer to an instance of type :c:enum:`gpio_pintype_e`.
+
+.. code-block:: c
+
+ enum gpio_pintype_e
+ {
+ GPIO_INPUT_PIN = 0, /* float */
+ GPIO_INPUT_PIN_PULLUP,
+ GPIO_INPUT_PIN_PULLDOWN,
+ GPIO_OUTPUT_PIN, /* push-pull */
+ GPIO_OUTPUT_PIN_OPENDRAIN,
+ GPIO_INTERRUPT_PIN,
+ GPIO_INTERRUPT_HIGH_PIN,
+ GPIO_INTERRUPT_LOW_PIN,
+ GPIO_INTERRUPT_RISING_PIN,
+ GPIO_INTERRUPT_FALLING_PIN,
+ GPIO_INTERRUPT_BOTH_PIN,
+ GPIO_INTERRUPT_PIN_WAKEUP,
+ GPIO_INTERRUPT_HIGH_PIN_WAKEUP,
+ GPIO_INTERRUPT_LOW_PIN_WAKEUP,
+ GPIO_INTERRUPT_RISING_PIN_WAKEUP,
+ GPIO_INTERRUPT_FALLING_PIN_WAKEUP,
+ GPIO_INTERRUPT_BOTH_PIN_WAKEUP,
+ GPIO_NPINTYPES
+ };
+
+.. c:macro:: GPIOC_REGISTER
+
+The ``GPIOC_REGISTER`` command registers a pin to receive a signal whenever
+there is an interrupt received on an input GPIO pin. This feature, of course,
+depends upon interript GPIO support in the platform specific code. Please
+refer to the documentation describing your target platform for futher
+information. The argument is the pointer to :c:type:`sigevent` value, a signal
+to be generated when the interrupt occurs.
+
+Typical use case is following:
+
+.. code-block:: c
+
+ struct sigevent notify;
+
+ notify.sigev_notify = SIGEV_SIGNAL;
+ notify.sigev_signo = SIGUSR1;
+
+ int ret = ioctl(fd, GPIOC_REGISTER, (unsigned long)¬ify);
+
+.. c:macro:: GPIOC_UNREGISTER
+
+The ``GPIOC_UNREGISTER`` command unresigters a pin and stop receiving signals
+for pin interrupt.
+
+.. c:macro:: GPIOC_SETPINTYPE
+
+The ``GPIOC_SETPINTYPE`` command can be used to change the GPIO pin type
+(from input pin to output pin, changing interrupt edges and similar). The
+types to set are listed in :c:enum:`gpio_pintype_e`.
+
+Application Example
+~~~~~~~~~~~~~~~~~~~
+
+An example application can be found in ``nuttx-apps`` repository under
+path ``examples/gpio``. It is an example application that allows you
+to read, write or configure GPIO pins.
+
+Configuration
+=============
+
+This section describes GPIO driver configuration in ``Kconfig``. The reader
+should refer to target documentation for target specific configuration.
+
+GPIO peripheral is enabled by ``CONFIG_DEV_GPIO``. Option
+``CONFIG_DEV_NPOLLWAITERS`` is used to specify the maximum number of threads
+that can be waiting on poll with default set to one. It is also possible
+to register signals with the GPIO driver. The number of allowed signals
+is configured with ``CONFIG_DEV_NSIGNALS``.
+
+IO Expander Device Drivers
+==========================
+
+IO Expander device drivers are chips that provides more GPIO pins, usually
+connected to the MCU with SPI or I2C bus. It is possible to register
+individual GPIO pins of the expander as a separate pins if needed. This
+option is enabled by ``CONFIG_GPIO_LOWER_HALF`` option. Please refer
+to `ioexpander documentation <https://nuttx.apache.org/docs/latest/components/drivers/special/ioexpander.html>`_
+for more description.
