Austrian Microsystems AS3935 Franklin lightning sensor device driver
2
+
3
+
Required properties:
4
+
- compatible: must be "ams,as3935"
5
+
- reg: SPI chip select number for the device
6
+
- spi-cpha: SPI Mode 1. Refer to spi/spi-bus.txt for generic SPI
7
+
slave node bindings.
8
+
- interrupt-parent : should be the phandle for the interrupt controller
9
+
- interrupts : the sole interrupt generated by the device
10
+
11
+
Refer to interrupt-controller/interrupts.txt for generic
12
+
interrupt client node bindings.
13
+
14
+
Optional properties:
15
+
- ams,tuning-capacitor-pf: Calibration tuning capacitor stepping
16
+
value 0 - 120pF. This will require using the calibration data from
17
+
the manufacturer.
18
+

+
Example:
20
+
21
+
as3935@0 {
22
+
compatible = "ams,as3935";
23
+
reg = <0>;
24
+
spi-cpha;
25
+
interrupt-parent = <&gpio1>;
26
+
interrupts = <16 1>;
27
+
ams,tuning-capacitor-pf = <80>;
