Ideal is to add the addition compatible string and device name etc to the driver to support the part under this part number. It's always nicer if a DT matches the part number on the part you can see on the board! Jonathan p.s. If you don't fancy writing the patch, but will happily test it really is compatible, let us know and I'm sure someone else will pick it up if I don't. > > Thanks in advance > Stefan > > [1] - https://www.st.com/resource/en/datasheet/iis328dq.pdf > [2] - https://www.st.com/resource/en/datasheet/cd00213470.pdf > -- > To unsubscribe from this list: send the line "unsubscribe linux-iio" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html
