I entered the following USB bug into kernel
This patch set adds Service Interval support for device mode.
When this mode is enabled core is able to send data any u(f) in current
service interval.
Also in this mode core is able to accept L1 tokens for ISOC IN endpoints.
Reference clock was added in the core to track SOF number internally.
Added GHWCFG4_SERVICE_INTERVAL_SUPPORTED and
DCTL_SERVICE_INTERVAL_SUPPORTED bits definitions to support
service interval based scheduling.

Added dwc2_gadget_dec_frame_num_by_one() function in gadget.c.
This function will be used to calculate descriptor frame number field
value. For service interval mode frame number in descriptor should point
to last (u)frame in the interval.

Latest NVIDIA GPU cards have a Cypress CCGx Type-C controller
over I2C interface.
This UCSI I2C driver uses I2C bus driver interface for communicating
with Type-C controller.

Latest NVIDIA GPU card has USB Type-C interface. There is a
Type-C controller which can be accessed over I2C.
This driver adds I2C bus driver to communicate with Type-C controller.
I2C client driver will be part of USB Type-C UCSI driver.
