On Intel platforms, if the debug target is connected with debug
host, enabling DCE bit in command register leads to a port hung
state. In the hung state, the host system will not see a port
connected status bit set. Hence debug target fails to be probed.
The state could be resolved by performing a

This patch series adds support for early printk through USB3 debug port.
USB3 debug port is described in xHCI specification as an optional extended

This patch adds a sysfs file for users to check 1) whether the debug
capability is implemented by hardware; 2) if supported, which state
does it stay at.

xHCI debug capability (DbC) is an optional functionality provided
by an xHCI host controller. Software learns this capability by
walking through the extended capability list in mmio of the host.
This patch introduces the code to probe and initialize the debug
capability hardware during early boot.
xHCI compatible USB3 host controller may provide debug capability
which enables low-level system debug over USB. In order to probing
this debug capability, Linux kernel needs to map and access the
mmio of the host controller during early boot.
This patch adds permenent fixmap pages in fixed_addres
This patch adds interfaces for bulk out and bulk in ops. These
interfaces could be used to implement early printk bootconsole
or hook to various system debuggers.

The microframe scheduler did a lot of work to pick the proper
microframe. Then dwc2_sched_periodic_split() went ahead and ignored
which microframe we picked if it ever needed to re-assign things.
Let's keep track of the uframe and then we'll always use it.
