+LEDs
+------
+
+The compatibility layer comes with simple reference nodes for attaching LEDs to any gpio pin. The format followed for these nodes is **led_P8_## / led_P9_##**. The **gpio-leds** driver is used by these reference nodes internally and allows users to easily create compatible led nodes in overlays for Black, AI and AI-64. For the definitions, you can see `bbai-bone-buses.dtsi#L16 <https://github.com/lorforlinux/BeagleBoard-DeviceTrees/blob/97a6f0daa9eab09633a2064f68a53b107d6e3968/src/arm/bbai-bone-buses.dtsi#L16>`_ & `bbb-bone-buses.dtsi#L16 <https://github.com/lorforlinux/BeagleBoard-DeviceTrees/blob/97a6f0daa9eab09633a2064f68a53b107d6e3968/src/arm/bbb-bone-buses.dtsi#L16>`_.

+PRU
+-------
+
+The overlay situation for PRUs is a bit more complex than with other peripherals. The mechanism for loading, starting and stopping the PRUs can go through either [https://www.kernel.org/doc/html/latest/driver-api/uio-howto.html UIO] or [https://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components/PRU-ICSS/Linux_Drivers/RemoteProc_and_RPMsg.html RemoteProc].

+TODO<br>
+For each of the pins with a GPIO, there should be a symlink that comes from the names
+*
+
+Methodology
+---------------
+
+The methodology for applied in the kernel and software images to expose the software interfaces is to be documented here. The most fundamental elements are the device tree entries, including overlays, and udev rules.
+
+Device Trees
+-------------
+
+udev rules

+
+10-of-symlink.rules
+**********************
+
+.. code-block::
+
+ #From: https://github.com/mvduin/py-uio/blob/master/etc/udev/rules.d/10-of-symlink.rules

+ TAG+="systemd", ENV{SYSTEMD_ALIAS}+="/dev/%E{OF_SYMLINK}"
+
+TBD
+****************
+
+.. code-block::
+
+ # Also courtesy of mvduin
+ # create symlinks for gpios exported to sysfs by DT
+ SUBSYSTEM=="gpio", ACTION=="add", TEST=="value", ATTR{label}!="sysfs", \
+ RUN+="/bin/mkdir -p /dev/bone/gpio", \
+ RUN+="/bin/ln -sT '/sys/class/gpio/%k' /dev/bone/gpio/%s{label}"
+
+
+Verification
+----------------
+
+TODO: The steps used to verify all of these configurations is to be documented here. It will serve to document what has been tested, how to reproduce the configurations, and how to verify each major triannual release. All faults will be documented in the issue tracker.
