From 82f53f9ee5770177eb102446cc3513bf07e2668a Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 12 Aug 2021 20:00:24 +0300 Subject: clk: fractional-divider: Introduce POWER_OF_TWO_PS flag The newly introduced POWER_OF_TWO_PS flag, when set, makes the flow to skip the assumption that the caller will use an additional 2^scale prescaler to get the desired clock rate.
