9 - reg: Physical base address and length of the controller's registers.
10 - clocks: Must contain an entry for each entry in clock-names.
11 See ../clocks/clock-bindings.txt for details.
12 - clock-names: Must include the following entries:
13 - mc: the module's clock input
14 - interrupts: The interrupt outputs from the controller.
15 - #reset-cells : Should be 1. This cell represents memory client module ID.
