TI BoosterPack GPIO header
GPIO pins exposed as BoosterPack headers on TI LaunchPads.
BoosterPack plug-in modules are available in 20 and 40 pin variants. The
20 pin variant has two 10 x 1 pin headers and the 40 pin variant has two
10 x 2 pin headers. Both variants are compatible and stackable.
The pins of the 20 pin variant and the outer row of the 40 pin variant are
numbered 1 through 20. The inner rows of the 40 pin variant are numbered 21
through 40. The BoosterPack pinout is depicted below:
1 3.3V 21 5V 40 GPIO 20 GND
2 Analog 22 GND 39 GPIO 19 GPIO / SPI CS
3 UART RXD 23 Analog 38 GPIO 18 GPIO
4 UART TXD 24 Analog 37 GPIO 17 GPIO
5 GPIO 25 Analog 36 GPIO 16 RESET
6 Analog 26 Analog 35 GPIO 15 SPI MOSI
7 SPI CLK 27 Analog 34 GPIO 14 SPI MISO
8 GPIO 28 Analog 33 GPIO 13 GPIO / SPI CS
9 I2C SCL 29 32 GPIO 12 GPIO / SPI CS
10 I2C SDA 30 31 GPIO 11 GPIO
Additional information about the BoosterPack pinout can be found at
http://processors.wiki.ti.com/index.php/BYOB or in the documentation for
a TI LaunchPad development kit,

Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.

The device will be notified when the power domain it belongs to is either
suspended or resumed.
* - ``zephyr,pm-device-runtime-auto``
- ``boolean``
- .. code-block:: none
Automatically configure the device for runtime power management after the
init function runs.
