+The CPU divider node serves as the sole clock for the CPU complex. It supports
+power-of-2 clock division, with a divider of "1" as the default highest-speed
+setting.
+
+Required properties:
+- compatible: shall be "brcm,brcmstb-cpu-clk-div"
+- reg: address and width of the divider configuration register
+- #clock-cells: shall be set to 0
+- clocks: phandle of clock provider which provides the source clock
+ (this would typically be a "fixed-clock" type PLL)
+- div-table: list of (raw_value,divider) ordered pairs that correspond to the
+ allowed clock divider settings
+- div-shift-width: least-significant bit position and width of divider value
+
+Optional properties:
+- clock-names: the clock may be named
+
+Example:
+ cpuclkdiv: cpu-clk-div@f03e257c {
+ compatible = "brcm,brcmstb-cpu-clk-div";
+ reg = <0xf03e257c 0x4>;
+ div-table = <0x00 1>;
+ div-shift-width = <0 5>;
+ #clock-cells = <0>;
+ clocks = <&cpupll>;
+ clock-names = "cpupll";
+ };
