True if and only if the device structure may be mutated.
Inherit this binding for devices that are runtime-modifiable, in-place.
This places the device structure into SRAM rather than Flash.
|
|
|
Devices to be multiplexed.
This property is required. |
|
|
Initial multiplexer selection.
This must be in the range [0, N-1], where N is the length of the
'devices' phandle list.
If unspecified, the default selection is zero in order to ensure that
the multiplexer is ready for use (i.e. one of the [0, N-1] multiplexed
devices is selected). Zero is, necessarily, the only possible valid
default value since the phandle list must have length >= 1.
Note: Specifying a value of 'selected' outside the range [0, N-1]
results in a compile-time error.

Deprecated properties not inherited from the base binding file.
(None)
Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “zephyr,devmux” compatible.

|
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.
|
|
|
indicates the operational status of a device
