Guys:
Has anyone gotten a DMIC to work with the '6309 under Linux 4.9?
I've reviewed Qualcomm's "Stereo Connector and Audio Routing" document, and successfully turned off UART0 by modifying apq8016-sbc.dtsi. And yet, I don't see any I/O activity at the pins mentioned there.
I'm currently investigating whether the pinmux settings provided with the kernel are correct, or that they're even there. I'm also not sure whether the amixer configuration that comes with Yocto's rpb-console-image for morty can properly set the capture path correctly.
Anyone have any ideas or suggestions?
