3.16.7-ckt8 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Chen-Yu Tsai <[email protected]> commit 9a5e6c7eb5ccbb5f0d3a1dffce135f0a727f40e1 upstream. The PLLs on newer Allwinner SoC's, such as the A31 and A23, have a N multiplier factor that starts from 1, not 0. This patch adds an option to the factor clk driver's config data structures to specify the base value of N.
