Subject: [RFC PATCH v1 00/14] Introduced new Cadence USBSS DRD Driver

This patch set introduce new Cadence USBSS DRD driver
to linux kernel.

The Cadence USBSS DRD Driver s a highly
configurable IP Core which can be
instantiated as Dual-Role Device (DRD),
Peripheral Only and Host Only (XHCI)
configurations.

The current driver has been validated with
FPGA burned. We have support for PCIe
bus, which is used on FPGA prototyping.

The host site of USBSS controller is compliance
with XHCI specification, so it works with
standard XHCI linux driver.
