Hi, > In v1, Stephen pointed out that the subject and description of your > patch talk about adjusting the supply. However, your patch _also_ > adjusts the audio routing. Thanks for your comment. The audio routing part change is to use the vdd-micb-supply regulator setting. And the vdd-micb-supply set the MIC power source as PP1800_L2C. + "VA DMIC0", "vdd-micb", + "VA DMIC1", "vdd-micb", + "VA DMIC2", "vdd-micb", + "VA DMIC3", "vdd-micb", Let me update the commit message again to make it more clear. Thanks! > It feels like the audio routing should be done in a separate patch and > that patch. > > -Doug
