+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 : 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-cpha;
+ interrupt-parent = <&gpio1>;
+ interrupts = <16 1>;
+ ams,tuning-capacitor-pf = <80>;
+};
