+* This macro polls an address periodically until a condition is met or till the
+* timeout occurs.
+* The minimum timeout for calling this macro is 100us. If the timeout is less
+* than 100us, it still waits for 100us. Also the unit for the timeout is 100us.
+* If the timeout is not a multiple of 100us, it waits for a timeout of
+* the next usec value which is a multiple of 100us.
+*
+* @param            IO_func - accessor function to read the register contents.
+*                   Depends on the register width.
+* @param            ADDR - Address to be polled
+* @param            VALUE - variable to read the value
+* @param            COND - Condition to checked (usually involves VALUE)
+* @param            TIMEOUT_US - timeout in micro seconds
+*
+* @return           0 - when the condition is met
+*                   -1 - when the condition is not met till the timeout period
+*
+* @note             none
