If we touch the DEVCONF1 via pinmux, and we have code in mach-omap2 that also touch DEVCONF1, without any knowledge (and locking) between those... So _maybe_ that's not an issue, as the pinmux config we have here is fixed, and done once at boot time, and maybe the code in mach-omap2 that touch DEVCONF1 is also ran just once and not at the same time as the pinmux. But I don't know if that's so.
