Hi, 
 
During read pinebookpro dts in 5.9-rc4, find:
 
              simple-audio-card,widgets =
                     "Microphone", "Mic Jack",
                     "Headphone", "Headphones",
                     "Speaker", "Speaker";
              simple-audio-card,routing =
 
 two "Speaker" widgets, duplicated or one should be "Speakers"
