Add a timestamping mechanism for buffer that provides accurate
event timestamps when using watermark. This mechanism estimates
device internal clock by comparing FIFO interrupts delta time and
device elapsed time computed by parsing FIFO data.
Take interrupt timestamp in hard irq handler and add IIO device
specific timestamp structures in device private allocation.

Core component of a new driver for InvenSense ICM-426xx devices.
It includes registers definition, main probe/setup, and device
utility functions.
ICM-426xx devices are latest generation of 6-axis IMU,
gyroscope+accelerometer and temperature sensor. This device
includes a 2K FIFO, supports I2C/I3C/SPI, and provides
intelligent motion features like pedometer, tilt detection,
and tap detection.

This patch changes the function uvc_video_pump to be a separate
scheduled worker. This way the completion handler of each usb request
and every direct caller of the pump has only to schedule the worker
instead of doing the request handling by itself.
Moving the request handling to one thread solves the locking problems
between the three queueing cases in the completion handler, v4l2_qbuf
and video_enable.
Many drivers handle the completion handlers directly in their interrupt
handlers. This patch also reduces the workload on each interrupt.
Test on RK3568 EVB1 USB 3.0 UVC, use the high priority dedicated
workqueue instead of the system_wq can help to improve the uvc
transfer performance.

(cherry picked from commit 43cd002387)
If miss isoc event happens, the current code just move the
current req to the tail of the pending list, and then stop
the active transfer with cmd DWC3_DEPCMD_ENDTRANSFER. After
these operations, the isoc endpoint wait for a XferNotReady
event to restart the transfer with the first pending req
from the pending_list.
If there are already reqs in the pending list when move the
miss isoc reqs to the tail of the pending list, some of the
reqs are out of order.
This patch first moves all of the reqs in the started list
to the tail of the cancelled list, and then move all of the
reqs in the pending list to the tail of the cancelled list.
At last move all of the reqs in the cancelled list to the
pending list. This can make sure all of the reqs are in order
when restart the isoc transfer later.
