So I guess I'll poke a bit harder at finding ways to make sure the LDOs on the twl4030 get turned off.. this patch looks like a good start (since the VUSB regulators are completely set up). VAUX3 seems to be inappropriately enabled on a lot of OMAP3 boards; short of fixing u-boot, that'd be another bit of low-hanging fruit. > Didn't know Dave was such a poet :) Well, I dunno about the rhyme or scansion, but I do sort of like the "feral code" imagery. It seems to highlight some key behaviors better than many more familiar terms! - Dave
