I had a note to myself to investigate using MODULE_FIRMWARE() but hadn't gotten to it yet; I'm glad to have you do that instead... Thank you. -Alex

Actually, yes, I should have thought of that too. The default used here just specifies the path name used *if the firmware file name is not specified in the DTB*. So I don't think this is correct regardless of whether the MDT file is split or not. I think that's what Bjorn is saying here. -Alex > > Regards, > Bjorn > >> + >> static const struct of_device_id ipa_match[] = { >> { >> .compatible = "qcom,msm8998-ipa", >> -- >> 2.17.1 >>
