Mike Turquette 105299381d cpufreq: kirkwood: use the powersave multiplexer ... The powersave clock acts like a multiplexer for the cpu, selecting either the clock signal derived from the cpu pll or from the ddr clock. This patch changes powersave from a gate clock to a mux clock to better reflect this behavior. This is a cleaner approach whereby the frequency of the cpu always matches the rate of powersave_clk. The cpufreq driver for the kirkwood platform no longer must parse this behavior out of various calls to clk_enable and clk_disable, but can instead simply select the parent cpu it wants when changing rate. Likewise when requesting the cpu rate we need only query powersave_clk's rate through the usual call to clk_get_rate. The new clock data and corresponding changes to the cpufreq driver are combined into this single commit to avoid a git bisect issue where this cpufreq driver fails to work properly between the commit that updates the kirkwood clock driver and the commit that changes how the cpufreq driver uses that clock.
