Initial Power Amplifier power in dBm.
This property is required. |
|
|
Maximum Power Amplifier power in dBm.
This property is required. |
|
|
Power Amplifier ramp time in microseconds.
This property is required. |
|
|
Voltage on PAVDD supply pin in millivolts.
This property is required. |
|
|
Power Amplifier selection for 2.4 GHz. A value of 'highest' selects the highest
available PA on the given device. A value of 'auto' dynamically selects the
optimal PA based on the output power configuration. Other values explicitly
select a specific PA.
Not all PAs are available on all devices, check device specific documentation.
If this property is not set, no 2.4 GHz PA is enabled.
Legal values: |
|
|
Power Amplifier selection for sub-GHz. A value of 'highest' selects the highest
available PA on the given device. Other values explicitly select a specific PA. If
this property is not set, no sub-GHz PA is enabled.
Legal values: |
|
|
Logical AND the radio active signal with the RF path selection (control) signal.
|
|
|
GPIO on which the RF path selection signal is emitted. Typically connected to the
control signal of an RF switch.
|
|
|
GPIO on which the radio active signal is emitted. Typically connected to the supply
of an RF switch to only enable it when the radio is in operation.
|
|
|
2 Mbps PHY support (Bluetooth 5.0 specification).
|
|
|
Coded PHY support for Long Range (Bluetooth 5.0 specification).
|
|
|
Constant Tone Extension transmission for Direction Finding in Angle
of Departure mode (Bluetooth 5.1 specification).
|
|
|
Constant Tone Extension reception with IQ sampling for Direction Finding
in Angle of Arrival mode. Requires ble-cte-tx-supported capability
(Bluetooth 5.1 specification).
|
|
|
BLE Channel Sounding feature support (Bluetooth 6.0 specification).
|
|
|
If set, indicates that the radio hardware supports high TX power settings.
This capability enables transmission beyond standard power levels
(typically >10 dBm).
This property should be treated as read-only and should not be overridden;
the correct value is provided for your target's SoC already.
|
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 “silabs,series2-radio” compatible.

|
Information used to address the device. The value is specific to
the device (i.e. is different depending on the compatible
property).
The "reg" property is typically a sequence of (address, length) pairs.
Each pair is called a "register block". Values are
conventionally written in hex.
For details, see "2.3.6 reg" in Devicetree Specification v0.4.
This property is required. See Important properties for more information. |
|
|
Information about interrupts generated by the device, encoded as an array
of one or more interrupt specifiers. The format of the data in this property
varies by where the device appears in the interrupt tree. Devices with the same
"interrupt-parent" will use the same format in their interrupts properties.
For details, see "2.4 Interrupts and Interrupt Mapping" in
Devicetree Specification v0.4.
This property is required. See Important properties for more information. |
|
|
Indicates the operational status of the hardware or other
resource that the node represents. In particular:
- "okay" means the resource is operational and, for example,
can be used by device drivers
- "disabled" means the resource is not operational and the system
should treat it as if it is not present
For details, see "2.3.4 status" in Devicetree Specification v0.4.
Legal values: See Important properties for more information. |
|
|
This property is a list of strings that essentially define what
type of hardware or other resource this devicetree node
represents. Each device driver checks for specific compatible
property values to find the devicetree nodes that represent
resources that the driver should manage.
The recommended format is "vendor,device", The "vendor" part is
an abbreviated name of the vendor. The "device" is usually from
the datasheet.
The compatible property can have multiple values, ordered from
most- to least-specific. Having additional values is useful when the
device is a specific instance of a more general family, to allow the
system to match the most specific driver available.
For details, see "2.3.1 compatible" in Devicetree Specification v0.4.
This property is required. See Important properties for more information. |
|
|
Optional names given to each register block in the "reg" property.
For example:
/ {
soc {
#address-cells = <1>;
#size-cells = <1>;
uart@1000 {
reg = <0x1000 0x2000>, <0x3000 0x4000>;
reg-names = "foo", "bar";
};
};
};
The uart@1000 node has two register blocks:
- one with base address 0x1000, size 0x2000, and name "foo"
- another with base address 0x3000, size 0x4000, and name "bar"
|
|
|
Extended interrupt specifier for device, used as an alternative to
the "interrupts" property.
For details, see "2.4 Interrupts and Interrupt Mapping" in
Devicetree Specification v0.4.
|
|
|
Optional names given to each interrupt generated by a device.
The interrupts themselves are defined in either "interrupts" or
"interrupts-extended" properties.
For details, see "2.4 Interrupts and Interrupt Mapping" in
Devicetree Specification v0.4.
|
|
|
If present, this refers to the node which handles interrupts generated
by this device.
For details, see "2.4 Interrupts and Interrupt Mapping" in
Devicetree Specification v0.4.
|
|
|
Human readable string describing the device. Use of this property is
deprecated except as needed on a case-by-case basis.
For details, see "4.1.2 Miscellaneous Properties" in Devicetree
Specification v0.4.
See Important properties for more information. |
|
|
Information about the device's clock providers. In general, this property
should follow conventions established in the dt-schema binding:
https://github.com/devicetree-org/dt-schema/blob/main/dtschema/schemas/clock/clock.yaml
|
|
|
Optional names given to each clock provider in the "clocks" property.
|
|
|
This property encodes the number of <u32> cells used by address fields
in "reg" properties in this node's children.
For details, see "2.3.5 #address-cells and #size-cells" in Devicetree
Specification v0.4.
|
|
|
This property encodes the number of <u32> cells used by size fields in
"reg" properties in this node's children.
For details, see "2.3.5 #address-cells and #size-cells" in Devicetree
Specification v0.4.

|
|
Optional names given to the DMA channel specifiers in the "dmas" property.
|

|
|
|
Optional names given to the IO channel specifiers in the "io-channels" property.
|
|
|
Mailbox / IPM channel specifiers relevant to the device.
|
|
|
Optional names given to the mbox specifiers in the "mboxes" property.
|
|
|
Power domain specifiers relevant to the device.
|

|
|
|
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.
|
|
|
List of power states that will disable this device power.
