I'm using vanilla staging Kernel, from Greg's tree: https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git/commit/?h=staging-next&id=7bc49cb9b9b8bad32536c4b6d1aff1824c1adc6c Plus the DWC2 fixup I wrote and DT changes you pointed (see enclosed). I can disable the audio overlay here, as I don't have anything connected to audio inputs/outputs.
