atmel-xplained-header
Vendor: Generic or vendor-independent
Description
GPIO pins exposed on Atmel Xplained headers.
The Xplained layout provide a standard 10 pin header. A board can have
one or more headers and can share pins. This connector was developed to
match with Atmel AVR XMEGA devices GPIO port plus power signals. The Atmel
Xplained Pro standard connector keep compatibility with this header and it
can be defined on every board with an Xplained Pro Connector extension and
every pin can be defined as general purpose GPIO.
The AVR XMEGA port was designed as:
Signal Main Function
Px0 SDA
Px1 SCL
Px2 RX
Px3 TX
Px4 SS
Px5 MOSI
Px6 MISO
Px7 SCK
GND
VDD

This binding provides a nexus mapping for 10 pins where pins are disposed
to have a even and odd column:
Connector
Bind Pin Name Pin Pin Pin Name Bind
0 I2C(SDA) 1 2 I2C(SCL) 1
2 UART(RX) 3 4 UART(TX) 3
4 SPI(CS0) 5 6 SPI(MOSI) 5
6 SPI(MISO) 7 8 SPI(SCK) 7
GND 9 10 VDD(+3.3V)

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
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.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
