+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
+ - interrupt-parent : should be the phandle for the interrupt controller
+ - interrupts : interrupt mapping for GPIO IRQ
+
+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 = /bits/ 8 <10>;
+};
