Description
These nodes are “i2c” bus nodes.
Zephyr I2C Emulation controller

This option is used when the I2C target is enabled and it can support
buffered mode for I2C target transfer. When 'false', the target will use
PIO (Programmed I/O) mode.
|
|
|
When added, read/write requests sent to this bus for a given address will
be forwarded to the specified phandle (must be another i2c bus). As an
example, if we wanted to forward any requests from i2c0@0x20 to i2c1, we
would use:
&i2c0 {
forward = <&i2c1 0x20>;
};

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.
|
|
|
Power domain the device belongs to.
The device will be notified when the power domain it belongs to is either
suspended or resumed.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
