While reviewing Tomeu's "Per-user clock constraints" series I saw that the Kirkwood cpufreq driver needed to use a new, public clk_is_enabled() which I hoped not to merge [0].
This led to some investigation as to why this was needed and with Andrew's help I came to realize that the powersave_clk on the kirkwood platform acts more like a clock signal multiplexer than a gate. This mux is unique to Kirkwood; none of the other mvebu platforms have it. This series updates the kirkwood clock driver to model the powersave_clk as a mux instead of a gate, and it updates and slightly simplifies the cpufreq driver to use this clock as a mux. Rafael & Viresh: I'd prefer to merge the cpufreq driver patch through the clock tree since Tomeu's changes to the clock core depend on it.
