Vendor: Semtech Corporation
Description¶
Semtech SX1272 LoRa Modem
Properties¶
Properties not inherited from the base binding file.

---|---|---|
|
|
GPIO connected to the modem's RESET/NRESET signal.
This signal is open-drain, active-high (SX1272/3) or
active-low (SX1276/7/8/9) as interpreted by the modem.
This property is required. |
|
|
Up to six pins that produce service interrupts from the modem.
These signals are normally active-high.
This property is required. |
|
|
Selects power amplifier output pin. This is required when neither
'rfo-enable-gpios' nor 'pa-boost-enable-gpios' is specified. In other
case this property is simply ignored.
Legal values: |
|
|
Antenna power enable pin.
|
|
|
RFI antenna input enable pin.
|
|
|
RFO antenna output enable pin.
|
|
|
PA_BOOST antenna output enable pin.
|
|
|
TCXO power enable pin.
|
|
|
Delay which has to be applied after enabling TCXO power.
|
|
|
Maximum clock frequency of device's SPI interface in Hz
This property is required. |
|
|
GPIO specifier that controls power to the device.
This property should be provided when the device has a dedicated
switch that controls power to the device. The supply state is
entirely the responsibility of the device driver.
Contrast with vin-supply.
|
|
|
Reference to the regulator that controls power to the device.
The referenced devicetree node must have a regulator compatible.
This property should be provided when device power is supplied
by a shared regulator. The supply state is dependent on the
request status of all devices fed by the regulator.
Contrast with supply-gpios. If both properties are provided
then the regulator must be requested before the supply GPIOS is
set to an active state, and the supply GPIOS must be set to an
inactive state before releasing the regulator.
|
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 “semtech,sx1272” compatible.
