[PATCH 01/10] clk: sunxi: Add module 0 (storage) style clock support for A80

Tue Dec 2 22:35:56 PST 2014
The module 0 style clocks, or storage module clocks as named in the
official SDK, are almost the same as the module 0 clocks on earlier
Allwinner SoCs. The only difference is wider mux register bits.
