Ideal is to add the addition compatible string and device name etc to the d= river 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 o= n 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 d= on't. >=20 > Thanks in advance > Stefan >=20 > [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"=20 > in the body of a message to majordomo@vger.kernel.org More majordomo=20 > info at http://vger.kernel.org/majordomo-info.html
