The xHCI driver currently has the IMOD set to 160, which
translates to an IMOD interval of 40,000ns (160 * 250)ns
Commit 0cbd4b34cda9 ("xhci: mediatek: support MTK xHCI host controller")
introduced a QUIRK for the MTK platform to adjust this interval to 20,
which translates to an IMOD interval of 5,000ns (20 * 250)ns. This is
due to the fact that the MTK controller IMOD interval is 8 times
as much as defined in xHCI spec.
Instead of adding more quirk bits for additional platforms, this patch
introduces the ability for vendors to set the IMOD_INTERVAL as is
optimal for their platform. By using device_property_read_u32() on
"imod-interval-ns", the IMOD INTERVAL can be specified in nano seconds.
If no interval is specified, the default of 40,000ns (IMOD=160) will be
used.
No bounds checking has been implemented due to the fact that a vendor
may have violated the spec and would need to specify a value outside of
the max 8,000 IRQs/second limit specified in the xHCI spec.

xHCI compatible USB host controllers(i.e. super-speed USB3 controllers)
can be implemented with the Debug Capability(DbC). It presents a debug
device which is fully compliant with the USB framework and provides the
equivalent of a very high performance full-duplex serial link. The debug
capability operation model and registers interface are defined in 7.6.8
of the xHCI specification, revision 1.1.
The DbC debug device shares a root port with the xHCI host. By default,
the debug capability is disabled and the root port is assigned to xHCI.
When the DbC is enabled, the root port will be assigned to the DbC debug
device, and the xHCI sees nothing on this port. This implementation uses
a sysfs node named <dbc> under the xHCI device to manage the enabling
and disabling of the debug capability.
When the debug capability is enabled, it will present a debug device
through the debug port. This debug device is fully compliant with the
USB3 framework, and it can be enumerated by a debug host on the other
end of the USB link. As soon as the debug device is configured, a TTY
serial device named /dev/ttyDBC0 will be created.

At present, TCPM code assumes that local device supports
variable/batt pdos and always selects the pdo with highest
possible power within the board limit. This assumption
might not hold good for all devices. To overcome this,
this patch makes TCPM only accept a source_pdo when there is
a matching sink pdo.
For Fixed pdos: The voltage should match between the
incoming source_cap and the registered snk_pdo
For Variable/Batt pdos: The incoming source_cap voltage
range should fall within the registered snk_pdo's voltage
range.
Also, when the cap_mismatch bit is set, the max_power/current
should be set to the max_current/power of the sink_pdo.
This is according to:
"If the Capability Mismatch bit is set to one
The Maximum Operating Current/Power field may contain a value
larger than the maximum current/power offered in the Source
Capabilities message’s PDO as referenced by the Object position field.
This enables the Sink to indicate that it requires more current/power
than is being offered. If the Sink requires a different voltage this
will be indicated by its Sink Capabilities message.

The source and sink caps should follow the following rules.
This patch validates whether the src_caps/snk_caps adheres
to it.
6.4.1 Capabilities Message
A Capabilities message (Source Capabilities message or Sink
Capabilities message) shall have at least one Power
Data Object for vSafe5V. The Capabilities message shall also
contain the sending Port’s information followed by up to
6 additional Power Data Objects. Power Data Objects in a
Capabilities message shall be sent in the following order:
1. The vSafe5V Fixed Supply Object shall always be the first object.
2. The remaining Fixed Supply Objects, if present, shall be sent
in voltage order; lowest to highest.
3. The Battery Supply Objects, if present shall be sent in Minimum
Voltage order; lowest to highest.
4. The Variable Supply (non-battery) Objects, if present, shall be
sent in Minimum Voltage order; lowest to highest.
Errors in source/sink_caps of the local port will prevent
the port registration. Whereas, errors in source caps of partner
device would only log them.

which matches the new usb_of_get_interface_node() helper that is used to

This code looks up a USB device node from a given parent USB device but
never dropped its reference to the returned node.
As only the address of the node is used for a later matching, the
reference can be dropped immediately.
Note that this trigger implementation confuses the description of the
USB device connected to a port with the port itself (which does not have
a device-tree representation).

Add OF device-tree support for USB interfaces.
USB "interface nodes" are children of USB "device nodes" and are
identified by an interface number and a configuration value:
&usb1 { /* host controller */
dev1: device@1 { /* device at port 1 */
compatible = "usb1234,5678";
reg = <1>;
#address-cells = <2>;
#size-cells = <0>;
interface@0,2 { /* interface 0 of configuration 2 */
compatible = "usbif1234,5678.config2.0";
reg = <0 2>;
};
};
};
The configuration component is not included in the textual
representation of an interface-node unit address for configuration 1:
&dev1 {
interface@0 { /* interface 0 of configuration 1 */
compatible = "usbif1234,5678.config1.0";
reg = <0 1>;
};
};
When a USB device of class 0 or 9 (hub) has only a single configuration
with a single interface, a special case "combined node" is used instead
of a device node with an interface node:
&usb1 {
device@2 {
compatible = "usb1234,abcd";
reg = <2>;
};
};
Combined nodes are shared by the two device structures representing the
USB device and its interface in the kernel's device model.
Note that, as for device nodes, the compatible strings for interface
nodes are currently not used.
For more details see "Open Firmware Recommended Practice: Universal
Serial Bus Version 1" and the binding documentation.

The expectation in the FUSB302 driver is that a TX_SUCCESS event
should occur after a message has been sent, but before a GCRCSENT
event is raised to indicate successful receipt of a message from
the partner. However in some circumstances it is possible to see
the hardware raise a GCRCSENT event before a TX_SUCCESS event
is raised. The upshot of this is that the GCRCSENT handling portion
of code ends up reporting the GoodCRC message to TCPM because the
TX_SUCCESS event hasn't yet arrived to trigger a consumption of it.
When TX_SUCCESS is then raised by the chip it ends up consuming the
actual message that was meant for TCPM, and this incorrect sequence
results in a hard reset from TCPM.
To avoid this problem, this commit updates the message reading
code to check whether a GoodCRC message was received or not. Based
on this check it will either report that the previous transmission
has completed or it will pass the msg data to TCPM for futher
processing. This way the incorrect ordering of the events no longer
matters.

* GICv4 Support for KVM/ARM
All ARM patches were in next-20171113. I have postponed most x86 fixes
to 4.15-rc2 and UMIP to 4.16, but there are fixes that would be good to
have already in 4.15-rc1:
* re-introduce support for CPUs without virtual NMI (cc stable)
and allow testing of KVM without virtual NMI on available CPUs
* fix long-standing performance issues with assigned devices on AMD
(cc stable)

...
A small batch of fixes, about 50% tagged for stable and the rest for recently
merged code.
There's one more fix for the >128T handling on hash. Once a process had
requested a single mmap above 128T we would then always search above 128T. The
correct behaviour is to consider the hint address in isolation for each mmap
request.
Then a couple of fixes for the IMC PMU, a missing EXPORT_SYMBOL in VAS, a fix
for STRICT_KERNEL_RWX on 32-bit, and a fix to correctly identify P9 DD2.1 but in
code that is currently not used by default.

Pull SCSI target updates from Nicholas Bellinger:
"This series is predominantly bug-fixes, with a few small improvements
that have been outstanding over the last release cycle.
As usual, the associated bug-fixes have CC' tags for stable.
Also, things have been particularly quiet wrt new developments the
last months, with most folks continuing to focus on stability atop 4.x
stable kernels for their respective production configurations.
Also at this point, the stable trees have been synced up with
mainline. This will continue to be a priority, as production users
tend to run exclusively atop stable kernels, a few releases behind
mainline.
The highlights include:
- Fix PR PREEMPT_AND_ABORT null pointer dereference regression in
v4.11+ (tangwenji)
- Fix OOPs during removing TCMU device (Xiubo Li + Zhang Zhuoyu)
- Add netlink command reply supported option for each device (Kenjiro
Nakayama)
- cxgbit: Abort the TCP connection in case of data out timeout (Varun
Prakash)
- Fix PR/ALUA file path truncation (David Disseldorp)
- Fix double se_cmd completion during ->cmd_time_out (Mike Christie)
- Fix QUEUE_FULL + SCSI task attribute handling in 4.1+ (Bryant Ly +
nab)
- Fix quiese during transport_write_pending_qf endless loop (nab)
- Avoid early CMD_T_PRE_EXECUTE failures during ABORT_TASK in 3.14+
