In OS descriptors handling, if ctrl->bRequestType is USB_RECIP_DEVICE
and w_index != 0x4 or (w_value >> 8) is true, it will not reset
req->length, but use the default value(-EOPNOTSUPP), and queue an
OS desc request with an invalid req->length. It always happens
on the platforms which use os_desc(for example: rk3366,rk3399),
and cause kernel panic as follows(use dwc3 driver):

This adds thermal zone node to rk3399 dtsi, rk3399 thermal data is
including the cpu and gpu sensor zone node.
At the moment, remove the rk3368 thermal data from rk399 dtsi.
The thermal zone node is the node containing all the required info
for describing a thermal zone, including its cooling device bindings. The
thermal zone node must contain, apart from its own properties, one sub-node
containing trip nodes and one sub-node containing all the zone cooling maps
The following is the parameter is introduced:
* polling-delay:
The maximum number of milliseconds to wait between polls
* polling-delay-passive:
The maximum number of milliseconds to wait between polls when performing
passive cooling.
* trips:
A sub-node which is a container of only trip point nodes required to describe
the thermal zone.
* cooling-maps:
A sub-node which is a container of only cooling device map nodes, used to
describe the relation between trips and cooling devices.
* cooling-device:
A phandle of a cooling device with its specifier, referring to which cooling
device is used in this cooling specifier binding. In the cooling specifier,
the first cell is the minimum cooling state and the second cell is the maximum
cooling state used in this map.

Whenever the current temperature is updated, the trip points immediately
below and above the current temperature are found. A sensor driver
callback `set_trips' is then called with the temperatures.
Lastly, The sensor will trigger the hardware high temperature interrupts
to increase the sampleing rate and throttle frequency to limit the temperature
rising When performing passive cooling.

This adds support for hardware-tracked trip points to the device tree
thermal sensor framework.
The framework supports an arbitrary number of trip points. Whenever
the current temperature is updated, the trip points immediately
below and above the current temperature are found. A sensor driver
callback `set_trips' is then called with the temperatures.
If there is no trip point above or below the current temperature,
the passed trip temperature will be LONG_MAX or LONG_MIN respectively.
In this callback, the driver should program the hardware such that
it is notified when either of these trip points are triggered.
When a trip point is triggered, the driver should call
`thermal_zone_device_update' for the respective thermal zone. This
will cause the trip points to be updated again.
If the `set_trips' callback is not implemented (is NULL), the framework
behaves as before.

Normally, the display regulator would be kept powered on by the
display/backlight driver, but we don't yet have a DT representation or
driver for this, as the PWM is controlled by the EC. Just force the
regulator on for now.
This wasn't needed on some boards yet, since they were forcing this
regulator "on." But for those where we might be controlling it, we need
this. (And it's harmless otherwise.)
This is necessary but not sufficient for getting UI up on my board.
