    This patch is to add debugfs support for ptp_qoriq. Current debugfs
    supports to control fiper1/fiper2 loopback mode. If the loopback mode
    is enabled, the fiper1/fiper2 pulse is looped back into trigger1/
    trigger2 input. This is very useful for validating hardware and driver
    without external hardware. Below is an example to enable fiper1 loopback.
