This patch series makes kzm9d to move to new clk implementation based on the common clock framework and device tree, when configured as a part of multi-platform. These patches do not remove sh-clkfwk version, even on emev2. Non multi-platform configuration still uses sh-clkfwk. Should be applie

Common clock framework version of emev2 clock support. smu_clkdiv and smu_gclk are handled. So far, reparent is not implemented, and is fixed to index #0. SMU and small numbers of clocks are described in emev2.dtsi. That function and numbers of clocks are equivalent to current sh-clkfwk version. I
