 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)
 
 Examples:
-        apll_pcie_ck: apll_pcie_ck@4a008200 {
+        apll_pcie_ck: apll_pcie_ck {
                 #clock-cells = <0>;
