+TI-NSPIRE Clocks
+
+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>;
+};
