+ * - Enable the PCI device using pci_enable_device

+ * init_waitqueue_head API
+ * - Set the memory address to be used by the HAL
+ * using ioh_1588_blpl_base_address_set API
+ * - Register the interrupt handler using request_irq
+ * API
+ * - Register the charecter driver using
+ * sregister_chrdev_region/
+ * alloc_chrdev_region APIs based on whether major
+ * number has been
+ * provided by the user or not.
+ * - Add the device to the system using the APIs
+ * cdev_init and
+ * cdev_add.
+ * - If any of the above calls fail, undo the steps
+ * performed before the failure and return
+ * appropraite error
+ * status.
+ * - Depending on the parameters passed during module
+ * load,
+ * enable/disable PTP clock synchronization control
+ * on GbE
+ * (using ioh_1588_eth_enable/ioh_1588_eth_disable
+ * API). /CAN
+ * (using ioh_1588_can_enable/ioh_1588_can_disable

+ * API
+ * -Note: For A0/A1 sample, test mode setting is enabled for
