We just found that this type of solution doesn't work on exynos5420, since the LOCK and CON registers aren't always 0x100 away from each other. Perhaps you can adjust to use a solution like Andrew proposed in <https://gerrit.chromium.org/gerrit/#/c/58411/>? That way we can avoid some churn of changing this code twice. The number of parameters to the register PLL function is starting to get unwieldy. At some point we'll probably want to pass in a structure. I wonder if now would be the time? Certainly it would be easier to handle changes to the code without touching all of the exynos variants...
