The earlier deployed LIS3LV02DL driver had already defined a few DT bindings that need to be supported by the new more generic driver and listed as compatible but deprecated bindings in the documentation. After this we can start to activate the new driver with the old systems where applicable. As part of this enablement: make us depend on the old drivers not being in use so we don't get a kernel with two competing drivers.
