semtech,sx1262 (on spi bus)¶

Description¶

Semtech SX1262 LoRa Modem

Properties¶

Properties not inherited from the base binding file.

Name	Type	Details
`reset-gpios`	`phandle-array`	GPIO connected to the modem's NRST signal. This signal is open-drain, active-low as interpreted by the modem. This property is required.
`busy-gpios`	`phandle-array`	GPIO connected to the modem's BUSY signal. This property is required.
`antenna-enable-gpios`	`phandle-array`	Antenna power enable pin.
`tx-enable-gpios`	`phandle-array`	Antenna switch TX enable GPIO. If set, the driver tracks the state of the radio and controls the RF switch.
`rx-enable-gpios`	`phandle-array`	Antenna switch RX enable GPIO. If set, the driver tracks the state of the radio and controls the RF switch.
`dio1-gpios`	`phandle-array`	GPIO connected to DIO1. This GPIO will be used as a generic IRQ line from the chip. This property is required.
`dio2-tx-enable`	`boolean`	Use DIO2 to drive an RF switch selecting between the TX and RX paths. When enabled, DIO2 goes high when the chip is transmitting.
`dio3-tcxo-voltage`	`int`	TCXO supply voltage controlled by DIO3 if present. See constants in dt-bindings/lora/sx126x.h.
`tcxo-power-startup-delay-ms`	`int`	Startup delay to let the TCXO stabilize after TCXO power on.
`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,sx1262” compatible.

Name	Type	Details
`reg`	`array`	register space This property is required. See Important properties for more information.
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) This property is required. See Important properties for more information.
`status`	`string`	indicates the operational status of a device Legal values: `'ok'`, `'okay'`, `'disabled'`, `'reserved'`, `'fail'`, `'fail-sss'` See Important properties for more information.
`compatible`	`string-array`	compatible strings This property is required. See Important properties for more information.
`reg-names`	`string-array`	name of each register space
`interrupts`	`array`	interrupts for device See Important properties for more information.
`interrupts-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`clocks`	`phandle-array`	Clock gate information
`clock-names`	`string-array`	name of each clock
`#address-cells`	`int`	number of address cells in reg property
`#size-cells`	`int`	number of size cells in reg property
`dmas`	`phandle-array`	DMA channels specifiers
`dma-names`	`string-array`	Provided names of DMA channel specifiers
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
