The Notes says that Pin A5 (CC) of the USB Type-C plug shall be connected

However, there is a large amount of such double Rp connected to Vbus

The USB host on Tegra3 works with 32-bit alignment. Previous code tried
to align the buffer, but it did align the wrapper struct instead, so
the buffer was at a constant offset of 8 bytes (two pointers) from
expected alignment. Since kmalloc() guarantees at least 8-byte
alignment already, the alignment-extending is removed.

In _dwc2_hcd_urb_enqueue(), "urb->hcpriv = NULL" is executed without

...
out:

When _dwc2_hcd_urb_enqueue() and _dwc2_hcd_urb_dequeue() are
concurrently executed, the NULL check of "urb->hcpriv" can be executed
before "urb->hcpriv = NULL". After urb->hcpriv is NULL, it can be used
in the function call to dwc2_hcd_urb_dequeue(), which can cause a NULL
pointer dereference.
This possible bug is found by an experimental static analysis tool
developed by myself. This tool analyzes the locking APIs to extract
function pairs that can be concurrently executed, and then analyzes the
instructions in the paired functions to identify possible concurrency
bugs including data races and atomicity violations. The above possible
bug is reported, when my tool analyzes the source code of Linux 6.5.
To fix this possible bug, "urb->hcpriv = NULL" should be executed with
holding the lock "hsotg->lock". After using this patch, my tool never
reports the possible bug, with the kernelconfiguration allyesconfig for
x86_64. Because I have no associated hardware, I cannot test the patch
in runtime testing, and just verify it according to the code logic.

DWC3 driver needs access to XHCI Extended Capabilities registers to
read number of usb2 ports and usb3 ports present on multiport controller.
Since the extcaps header is sufficient to parse this info, move port_count
related macros and structure from xhci.h to xhci-ext-caps.h.

Add the compatible string for SC8280 Multiport USB controller from
Qualcomm.
There are 4 power event irq interrupts supported by this controller
(one for each port of multiport). Added all the 4 as non-optional
interrupts for SC8280XP-MP
Also each port of multiport has one DP and oen DM IRQ. Add all DP/DM
IRQ's related to 4 ports of SC8280XP Teritiary controller.
Also added ss phy irq for both SS Ports.

The OS, such as ChromeOS, uses Android Runtime to run Android applications.
This necessitates supporting tools, for example, Android Debugger (ADB).
On host to host setup xHC.DbC shall support ADB with USB. This requires
user space to control USB roles.
Enable user space control to modify the USB Type-C role. At run time
it will create a role attribute in /sys/class/usb_role/<switch>/.
Attribute can be modified based on the values suggested in the
Documentation/ABI/testing/sysfs-class-usb_role.

Enabling the tps65217-charger driver/module causes an interrupt conflict
with the vbus driver resulting in a probe failure.
The conflict is resolved by changing both driver's threaded interrupt
request function from IRQF_ONESHOT to IRQF_SHARED.
