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

In case when some EP IN is frequently reused, i.e. enabled/disabled by
function driver. It is required to clear TxFIFO number field in DIEPCTL
register before setting new number. Otherwise there is probability to
have same TxFIFO number for different EP's because of OR operator.

Dear All,
While playing with FunctionFS I have noticed that high speed descriptors passed
from userspace get overwritten by usb_ep_autoconfig() function. It happens for
bulk endpoints, to be precise.
At the time of this writing (5.0-rc4) there are 6 users of usb_ep_autoconfig(),
who call it for d
usb_ep_autoconfig() treats the passed descriptor as if it were an fs
descriptor. In particular, for bulk endpoints, it clips wMaxPacketSize
to 64. This patch preserves the original value.

The moved code refers to non-super speed endpoints only. This patch also
makes the comment stress the fact, that autoconfigured descriptor might
need some adjustments.
