The time_t type and time_to_tm() function are deprecated because
of y2038 problems. In this driver, they are used to pretty-print
the timestamp of the firmware build. This is fine as long as
we don't get a firmware build past 2038.
Converting to time64_t and time64_to_tm() avoids the deprecated
interfaces and works until 2106, when the firmware-defined
data structure overflows.

Fix to return error code -ENOMEM from the usb_create_shared_hcd()
error handling case instead of 0, as done elsewhere in this function.

Add support for the on-chip XUSB controller present on Tegra SoCs. This
controller, when loaded with external firmware, exposes an interface
compliant with xHCI. This driver loads the firmware, starts the
controller, and is able to service host-specific messages sent by the
controller's firmware.
The controller also supports USB device mode as well as powergating
of the SuperSpeed and host-controller logic when not in use, but
support for these is not yet implemented.
