So far we don't have any mechanism in the driver that gives ODM information. As far as generic soc_device_attribute's vendor field is concerned we use Qualcomm since this will be true for SoC. For hardware type and sub-types the various relevant values in SMEM are numeric values and indeed it would be very difficult to estimate how some other ODM will use the same number. So for the h/w types and sub-types can we keep the numeric values rather than showing strings as attribute values. We can leave the interpretation of these values to ODM specific code. Will wait for your feedback so that I can take care of it accordingly in the next patch set.
