  1. I rebuilt the 4.4.7-bone-rt-r9 kernel using Robert C Nelson's bb-kernel repo scripts. I modified sound/soc/davinci/davinci-mcasp.c to print some diagnostics. Rebooted, then executed the following. Note that BB-BONE-AUDI-02.dts is (https://github.com/RobertCNelson/bb.org-overlays/blob/master/src/arm/BB-BONE-AUDI-02-00A0.dts), and the base DTB is http://pastebin.com/5vVEdAKt.
