1 Austrian Microsystems AS3935 Franklin lightning sensor device driver
4 - compatible: must be "ams,as3935"
5 - reg: SPI chip select number for the device
6 - spi-max-frequency: specifies maximum SPI clock frequency
7 - spi-cpha: SPI Mode 1. Refer to spi/spi-bus.txt for generic SPI
9 - interrupt-parent : should be the phandle for the interrupt controller
10 - interrupts : the sole interrupt generated by the device
12 Refer to interrupt-controller/interrupts.txt for generic
13 interrupt client node bindings.
16 - ams,tuning-capacitor-pf: Calibration tuning capacitor stepping
17 value 0 - 120pF. This will require using the calibration data from
19 - ams,nflwdth: Set the noise and watchdog threshold register on
20 startup. This will need to set according to the noise from the
21 MCU board, and possibly the local environment. Refer to the
22 datasheet for the threshold settings.
