  * Description:
- *   Perform architecture-specific initialization of the touchscreen.
- *   This function must be called directly from application.
+ *   Each board that supports a touchscreen device must provide this function.
+ *   This function is called by application-specific, setup logic to
+ *   configure the touchscreen device.  This function will register the driver
+ *   as /dev/inputN where N is the minor device number.
+ *
+ * Input Parameters:
+ *   minor   - The input device minor number
+ *
+ * Returned Value:
+ *   Zero is returned on success.  Otherwise, a negated errno value is
+ *   returned to indicate the nature of the failure.
