Hello Guenter Thank you again for reviewing my patches! It was the first time for me :-) to add something to the kernel. >> +- vref-supply >> + The external reference in microvolt for this device is set to this >> value. >> + If it does not exists the reference will be set to 3300000uV >> (3.3V). > > s/exists/exist/ > Sorry for the noise and thank you for the hint. >> + >> +Example: >> + >> +adc@6 { >> + compatible = "national,adcxx2s"; >> + reg = <6 0>; >> + spi-max-frequency = <1000000>; > > I asssume that means that standard spi properties are accepted / > required, > which I think should be documented. We'll need input from Rob for that. Yes this is a standard option. I have added this because "Documentation/devicetree/bindings/hwmon/lm70.txt" did the same. This was my pattern. I will send a follow up patch set if this is clarivied. Let me know if this is needed or not.
