Not overly common (in the parts we have seen in IIO so far), but best to allow for it becoming a general property in the future and actual units definitely the way to go. > >> + - adi,dc_dc_maxv: >> + Valid values for the maximum allowed Vboost voltage supplied by >> + the dc-to-dc converter is: >> + 0: 23 V. >> + 1: 24.5 V. >> + 2: 27 V. >> + 3: 29.5 V. > > Same here. > > Rob > > -- > To unsubscribe from this list: send the line "unsubscribe linux-iio" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html > -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
