Specifically: * It adds saving and restoring of pincontrol registers. * It fixes eint wakeups. This set of two patches was verified on a backport of the current pinmux code onto 3.8 on a Samsung ARM Chromebook. Suspend/resume does not seem functional on the ARM Chromebook on current ToT Linux so I couldn't validate there. This gets us one step closer, though! Since patches applied cleanly I'm fairly certain that they will work on ToT as well as they do in our tree. These patches have only been tested on exynos5250. I have made an effort to support other samsung boards (even those with two CONF registers), but that support is untested. Tomasz Figa has said that he has similar patches in development. I'm posting what we have here but if Tomasz's patches end up being more suitable I have no objections to taking them over these (or of Tomasz wants to merge the two?).
