Add a 'select COMMON_CLK' to your Kconfig and do a:

	clk_dummy = clk_fixed("dummy", 0);
	clk_ref_3 = clk_fixed("ref3", 3 * 1000 * 1000);
	clk_ref_1 = clk_fixed("ref1", 1 * 1000 * 1000);

Then you can drop your clk code and get a clk_dump command
which you can use to see what clocks you have.

Please consolidate the initcalls. A single function for the three above
is enough.

Please add the UART index to the function name.

The address is wrong. Please remove this paragraph completly
