-Subject: [PATCH] clk: iproc: Fix PLL output frequency calculation
-
-This patch affects the clocks that use fractional ndivider in their
-PLL output frequency calculation. Instead of 2^20 divide factor, the
-clock's ndiv integer shift was used. Fixed the bug by replacing ndiv
-integer shift with 2^20 factor.
