It seems to me this is an I2C device so the following alias could load it:<br>
<br>
modules.alias:alias i2c:lis3lv02d <span class="gmail_default" style="font-family:arial,helvetica,sans-serif"></span>lis3lv02d_i2c<br></blockquote><div><br></div><div style="font-family:arial,helvetica,sans-serif" class="gmail_default">Apparently it could be both I2C or SPI, as I find <span class="gmail_default" style="font-family:arial,helvetica,sans-serif"></span>lis3lv02d_spi.c as well. I don't really know if this device sits on I2C bus or SPI.</div><div style="font-family:arial,helvetica,sans-serif" class="gmail_default"><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
