The upshot of the discussion Jean referenced was that the there were a number of other devices / sensors that will form part of the same system. For an initial bash I'm throwing in a couple of accelerometers, ADC's and probably one or two other sensors as well. Haven't come up with a good name as yet, but the point is that accelerometers would be just part of the relevant subsystem. Based on one suggestion (and current layout in my source tree), drivers/industrialio/accelerometer drivers/industrialio/adc and crucially for all those weird and wonderful sensors, drivers/industrialio/misc The reason for making it an io system is that many chips combine ADCs and DACs. Also suggestions for alternative names would be most welcome. Still, it may take some time to iron out the various kinks in this system and get it fully tested, so may be worth putting stuff elsewhere for now with the intention to move it as and when the more unified stuff has been written. Also, the LI3L02DQ (very similar to the chip you are using) is one of my test chips, so combining the two drivers should be straight forward. Also the driver I have is SPI only, so this may give us an easy way to test a combined driver. Jonathan
