And that I just have a "squirreled away" version of the TRM which made me wonder what is going on. >From this discussion I read that for X15 there is a different PMIC (Palmas derived, but not a twl6037) so that it needs something different. So my proposal would be to keep the MUX_MODE1 (because it works on OMAP5+TWL6037) as proposed by Tony. Maybe after adding a comment that MUX_MODE1 is a weakly documented feature. And the X15 board can "patch" it after using the omap5-board-common.dtsi to whatever it needs to fix it.
