Austrian Microsystems AS3935 Franklin lightning sensor device driver
Required properties:
- compatible: must be "ams,as3935"
- reg: SPI chip select number for the device
- spi-max-frequency: specifies maximum SPI clock frequency
- spi-cpha: SPI Mode 1. Refer to spi/spi-bus.txt for generic SPI
slave node bindings.
- interrupt-parent : should be the phandle for the interrupt controller
- interrupts : the sole interrupt generated by the device
Refer to interrupt-controller/interrupts.txt for generic
interrupt client node bindings.
Optional properties:
- ams,tuning-capacitor-pf: Calibration tuning capacitor stepping
value 0 - 120pF. This will require using the calibration data from
the manufacturer.
Example:
as3935@0 {
compatible = "ams,as3935";
reg = <0>;
spi-max-frequency = <400000>;
spi-cpha;
interrupt-parent = <&gpio1>;
interrupts = <16 1>;
ams,tuning-capacitor-pf = <80>;
};
