Can, but don't. That's my worry. 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.
