Hi Jonathan, Stefan,
LIS331DLH and IIS327DQ are compatible.
Mainly difference is the packaging since IIS is designed for industrial applications.
If you can give it a shot will be great before adding the compatible string.
thanks for confirmation.
Br,
Denis

Hi,
i want to use the ST IIS328DQ [1] on a ARM board with Linux. The iio
subsystem has this st_accel driver. But i didn't find any reference to
the IIS328DQ, so i started comparing the datasheets and found the ST
LIS331DLH [2].
Given it reports the same WHO_AM_I of 0x32 it better be compatible or they are being very unhelpful!
Since i didn't have the hardware yet, i've the following questions:
Does the st_accel driver support the IIS328DQ?
Not if it's not listed - though it might work.
Should i choose the st,lis331dlh compatible for devicetree?
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.
after receiption of the hardware and testing i will send a patch.
Best regards
Stefan
Thanks in advance
Stefan
