-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.
- - 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.
- - ams,nflwdth: Set the noise and watchdog threshold register on
- startup. This will need to set according to the noise from the
- MCU board, and possibly the local environment. Refer to the
- datasheet for the threshold settings.
