+Austrian Microsystems AS3935 Franklin lightning sensor device driver
+
+Required properties:
+	- compatible: must be "ams,as3935"
+	- reg: SPI chip select number for the device
+	- 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 : interrupt mapping for GPIO IRQ
+
+	Refer to interrupt-controller/interrupts.txt for generic
+	interrupt client node bindings.
+
+Optional properties:
+	- ams,tune-cap: Calibration tuning capacitor stepping value 0 - 15.
+	  Range of 0 to 120 pF, 8pF steps. This will require using the
+	  calibration data from the manufacturer.
+
+Example:
+
+as3935@0 {
+	compatible = "ams,as3935";
+	reg = <0>;
+	spi-cpha;
+	interrupt-parent = <&gpio1>;
+	interrupts = <16 1>;
+	ams,tune-cap = <10>;
