clk: iproc: Fix PLL output frequency calculation 2015-12-09T19:31:16+00:00 Simran Rai ssimran@broadcom.com 2015-10-19T22:27:19+00:00 5e5ed96b6766aca3bab1972ee2602b96fa335c05 commit 63243a4da7d0dfa19dcacd0a529782eeb2f86f92 upstream. 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.
