Here is one. I have two versions of the same IP. The first version in one chip has sw_version register that returns 1.0. The second version which has more capabilities has 1.1 in it. Is it OK to use? compatible="qcom,hidma-mgmt-1.0", "qcom,hidma-mgmt" for now and compatible="qcom,hidma-mgmt-1.1", "qcom,hidma-mgmt" later for the second chip? 1.1 is backwards compatible with 1.0 BTW. Since the same IP goes into multiple chips, why would you list the chip name here and submit patches multiple times for each single chip. or to follow what Timur did, I can do this. "qcom,qdf2xxx-hidma-mgmt-1.0" qdf2xxx would become the chip family. -- Sinan Kaya Qualcomm Technologies, Inc. on behalf of Qualcomm Innovation Center, Inc.
