semtech,sx1276 (on spi bus)

Vendor: Semtech Corporation

Description

Semtech SX1276 LoRa Modem

Properties

Node specific properties

Base properties

Properties not inherited from the base binding file.

Name

Type

Details

reset-gpios

phandle-array

 
GPIO connected to the sensor NRST signal.

This signal is open-drain, active-low as interpreted by the
modem.

This property is required.

dio-gpios

phandle-array

 
Up to six pins that produce service interrupts from the modem.

These signals are normally active-high.

This property is required.

power-amplifier-output

string

 
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: 'rfo', 'pa-boost'

antenna-enable-gpios

phandle-array

 
Antenna power enable pin.

rfi-enable-gpios

phandle-array

 
RFI antenna input enable pin.

rfo-enable-gpios

phandle-array

 
RFO antenna output enable pin.

pa-boost-enable-gpios

phandle-array

 
PA_BOOST antenna output enable pin.

tcxo-power-gpios

phandle-array

 
TCXO power enable pin.

tcxo-power-startup-delay-ms

int

 
Delay which has to be applied after enabling TCXO power.

spi-max-frequency

int

 
Maximum clock frequency of device's SPI interface in Hz

This property is required.

supply-gpios

phandle

 
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.

vin-supply

phandle

 
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.

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,sx1276” compatible.
