Required properties:
-- compatible : shall be "ti,dra7-apll-clock"
+- compatible : shall be "ti,dra7-apll-clock" or "ti,omap2-apll-clock"
- #clock-cells : from common clock binding; shall be set to 0.
- clocks : link phandles of parent clocks (clk-ref and clk-bypass)
- reg : address and length of the register set for controlling the APLL.
It contains the information of registers in the following order:
- "control" - contains the control register base address
- "idlest" - contains the idlest register base address
+ "control" - contains the control register offset
+ "idlest" - contains the idlest register offset
+ "autoidle" - contains the autoidle register offset (OMAP2 only)
+- ti,clock-frequency : static clock frequency for the clock (OMAP2 only)
+- ti,idlest-shift : bit-shift for the idlest field (OMAP2 only)
+- ti,bit-shift : bit-shift for enable and autoidle fields (OMAP2 only)
