IO Expander Device Drivers
==========================
+
+- ``include/nuttx/ioexpander/ioexpander.h`` and
``include/nuttx/ioexpander/gpio.h``.
+ All structures and APIs needed to work with ioexpander drivers are provided
in
+ this header file.
+
+- ``struct ioexpander_ops_s``. Each ioexpand device driver must implement
+ an instance of ``struct ioexpander_ops_s``. That structure defines a
+ call table with the methods, and we also provide macros to help access
methods.
+
+- we also provide method ``gpio_lower_half`` to make ioexpander compatible
with normal gpio.
+
+- **Binding ioexpander Drivers**. ioexpander drivers are not normally directly
+ accessed by user code, we should always get lower level drivers, for
example I2C,
+ and map extended gpio feature same asa normal gpio. See for example,
+ ``int nrf52_sx1509_initialize(void)``
+ in ``boards/arm/nrf52/thingy52/src/nrf52_sx1509.c``. In general, the binding
+ sequence is:
+
+ #. Get an instance of ``struct i2c_master_s`` from the
+ hardware-specific I2C device driver, and
+ #. Provide that instance and configurations to the ioexpander
initialization method
+ to get the ``struct ioexpander_dev_s`` ioe device instance.
+ #. Then use ioe device instance to do ioexpander operations, or use
``gpio_lower_half``
+ to make ioexpand compatible with normal gpio.
+
+
+- **Examples**: ``drivers/ioexpander/pca9555.c``,
+ ``drivers/input/aw86225.c``,
+ ``drivers/analog/lmp92001.c``,
+ ``drivers/ioexpander/ioe_rpmsg.c``,

+Device Tree
+====================
+
+Overview
+--------
+
+Currently, NuttX supports parsing of FDT(Flattened Device Tree) using libfdt, a
+utility library for reading and manipulating the binary format:
+
+https://github.com/dgibson/dtc/
+
+Based on that, NuttX has implemented some common functions to get properties.
+Device Tree support in NuttX will reduce the configuration of chips/boards,
+it is not used in NuttX kernel framework yet.
+
+How to use
+-----------
+
+1. Enable Device Tree and libfdt
+
+Enable the Kconfig settings:
+
+ .. code-block:: console
+
+ CONFIG_DEVICE_TREE=y /* Enable Device Tree */
+ CONFIG_LIBFDT=y /* Enable utility library */
+
+2. Register the DTB address
+
+Use fdt_register to set the DTB Address in NuttX
+
+3. Parse the DTB
+
+Chip/board will use fdt_get to get the DTB Address, and then use fdt_* APIs to
+parse the DTB properties.

Simulated interrupt handling logic would set ``g_in_interrupt`` on entry and
clear it on exit (perhaps it would be better to have a counter and increment it
interrupt entry and decrement it on exit?). The interrupt handler would also
need to clear ``g_context_regs`` on entry. ``up_interrupt_contest()`` would
then just report the state of the boolean.
