-Required properties:
-- compatible: Valid compatible properties include:
-       "lsi,nspire-cx-ahb-divider" for the AHB divider in the CX model
-       "lsi,nspire-classic-ahb-divider" for the AHB divider in the older model
-       "lsi,nspire-cx-clock" for the base clock in the CX model
-       "lsi,nspire-classic-clock" for the base clock in the older model
-
-- reg: Physical base address of the controller and length of memory mapped
-       region.
-
-Optional:
-- clocks: For the "nspire-*-ahb-divider" compatible clocks, this is the parent
-       clock where it divides the rate from.
-
-Example:
-
-ahb_clk {
-       #clock-cells = <0>;
-       compatible = "lsi,nspire-cx-clock";
-       reg = <0x900B0000 0x4>;
-       clocks = <&base_clk>;
-};
