commit ef7d9f8e7fe258e90757f6b7528e90573b8e2541 Author: Julius Werner jwerner@chromium.org Date: Tue Sep 6 14:09:16 2016 -0700
rockchip: Correct and standardize clock divisor range assertions
Some of the asserts for valid clock divisor ranges were off by one. This patch corrects them and writes them all in a consistent way.
