generic-fem-two-ctrl-pins
Vendor: Generic or vendor-independent
Description
This is a representation of generic radio Front-End Module (FEM)
that has a two-pin control interface (CTX, CRX).
The CTX control pin is used to enable the Power Amplifier (PA) in
the transmit path. This is therefore sometimes referred to as
the "PA pin" in other contexts.
The CRX control pin is used to enable the Low Noise Amplifier
(LNA) in the receive path, and is sometimes referred to as
the "LNA pin" in other contexts.
Each of these pins is optional, and may be omitted if not present.
(Though if you do specify a pin, you must also specify its
corresponding settle-time-us property.)

|
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.
|
|
|
List of power states that will disable this device power.
|
|
|
indicates the operational status of a device
