When choose randconfig for kernel build, it reports below warning:
"warning: (USB_OTG_FSM && FSL_USB2_OTG && USB_MV_OTG) selects USB_OTG
which has unmet direct dependencies (USB_SUPPORT && USB && PM)"
In fact, USB_OTG is visible symbol and depends on PM, so the driver
needs to depend on it to reduce dependency problem.

Clear device initiated resume variables once device is fully up and running
in U0 state.
Resume needs to be signaled for 20ms for usb2 devices before they can be
moved to U0 state.
An interrupt is triggered if a device initiates resume. As we handle the
event in interrupt context we can not sleep for 20ms, so we instead set
a resume flag, a timestamp, and start the roothub polling.
The roothub code will later move the port to U0 when it finds a port in
resume state with the resume flag set, and timestamp passed by 20ms.
A host initiated resume is however not done in interrupt context, and
host initiated resume code will directly signal resume, wait 20ms and then
move the port to U0.
These two codepaths can race, if we are in the middle of a host initated
resume, while sleeping for 20ms, we may handle a port event and find the
port in resume state. The port event handling code will assume the resume
was device initiated and set the resume flag and timestamp.
Root hub code will however not catch the port in resume state again as the
host initated resume code has already moved the port to U0.
The resume flag and timestamp will remain set for this port preventing port
from suspending again (LPM setting port to U3)
Fix this for now by always clearing the device initated resume parameters
once port is in U0

Function ep_ring_is_processing() checks the dequeue pointer
in endpoint context to know whether an endpoint is busy with
processing TRBs. This is not correct since dequeue pointer
field in an endpoint context is only valid when the endpoint
is in Halted or Stopped states. This buggy code causes audio
noise when playing sound with USB headset connected to host
controllers which support CFC (one of xhci 1.1 features).

Existing Intel xHCI controllers require a delay of 1 mS,
after setting the CMD_RESET bit in command register, before
accessing any HC registers. This allows the HC to complete
the reset operation and be ready for HC register access.
Without this delay, the subsequent HC register access,
may result in a system hang, very rarely.
Verified CherryView / Braswell platforms go through over
5000 warm reboot cycles (which was not possible without
this patch), without any xHCI reset hang.

some fixes for Rockchip SoCs on dwc2 and a fix on
dwc3 to let it report lower speeds than

Following changes that appeared in lk 4.0.0, the gadget udc driver for
some ARM based Atmel SoCs (e.g. at91sam9x5 and sama5d3 families)
incorrectly deduced full-speed USB link speed even when the hardware
had negotiated a high-speed link. The fix is to make sure that the
UDPHS Interrupt Enable Register value does not mask the SPEED bit
in the Interrupt Status Register.
For a mass storage gadget this problem lead to failures when the host
had a USB 3 port with the xhci_hcd driver. If the host was a USB 2
port using the ehci_hcd driver then the mass storage gadget worked
(but probably at a lower speed than it should have).

In some SoCs, dwc3 is implemented as a USB2.0 only
core, meaning that it can't ever achieve SuperSpeed.
Currect driver always sets gadget.max_speed to
USB_SPEED_SUPER unconditionally. This can causes
issues to some Host stacks where the host will issue
a GetBOS() request and we will reply with a BOS
containing Superspeed Capability Descriptor.
At least Windows seems to be upset by this fact and
prints a warning that we should connect $this device
to another port.

Here are a few changes in musb_h_tx_flush_fifo().
- It has been observed that sometimes (if not always) musb is unable
to flush tx fifo during urb dequeue when disconnect a device. But
it seems to be harmless, since the tx fifo flush is done again in
musb_ep_program() when re-use the hw_ep.
But the WARN() floods the console in the case when multiple tx urbs
are queued, so change it to dev_WARN_ONCE().
- applications could queue up many tx urbs, then the 1ms delay could
causes minutes of delay in device disconnect. So remove it to get
better user experience. The 1ms delay does not help the flushing
anyway.
- cleanup the debug code - related to lastcsr.
----
Note: The tx fifo flush issue has been observed during device disconnect
on AM335x.
To reproduce the issue, ensure tx urb(s) are queued when unplug the usb
device which is connected to AM335x usb host port.
I found using a usb-ethernet device and running iperf (client on AM335x)
has very high chance to trigger the problem.
Better to turn on dev_dbg() in musb_cleanup_urb() with CPPI enabled to
see the issue when aborting the tx channel.

In commit 734643dfbd ("usb: dwc2: host: add flag to reflect bus
state") we changed dwc2_port_suspend() not to set the lx_state
anymore (instead it sets the new bus_suspended variable). This
introduced a bug where we would fail to detect device insertions if:
1. Plug empty hub into dwc2
2. Plug USB flash drive into the empty hub.
3. Wait a few seconds
4. Unplug USB flash drive
5. Less than 2 seconds after step 4, plug the USB flash drive in again.
The dwc2_hcd_rem_wakeup() function should have been changed to look at
the new bus_suspended variable.
Let's fix it. Since commit b46146d59f ("usb: dwc2: host: resume root
hub on remote wakeup") talks about needing the root hub resumed if the
bus was suspended, we'll include it in our test.
It appears that the "port_l1_change" should only be set to 1 if we were
in DWC2_L1 (the driver currently never sets this), so we'll update the
former "else" case based on this test.

The comment for ahbcfg for rk3066 parameters (also used for rk3288)
claimed that ahbcfg was INCR16, but it wasn't. Since the bits weren't
shifted properly, the 0x7 ended up being masked and we ended up
programming 0x3 for the HBstLen. Let's set it to INCR16 properly.
As per Wu Liang Feng at Rockchip this may increase transmission
efficiency. I did blackbox tests with writing 0s to a USB-based SD
reader (forcefully capping CPU Freq to try to measure efficiency):
cd /sys/devices/system/cpu/cpu0/cpufreq
echo userspace > scaling_governor
echo 126000 > scaling_setspeed
for i in $(seq 10); do
dd if=/dev/zero of=/dev/sdb bs=1M count=750
done
With the above tests I found that speeds went from ~15MB/s to ~18MB/s.
Note that most other tests I did (including reading from the same USB
reader) didn't show any difference in performance.

The DEVICE_HWI type was added under the faulty assumption that Huawei
devices based on Qualcomm chipsets and firmware use the static USB
interface numbering known from Gobi devices. But this model does
not apply to Huawei devices like the HP branded lt4112 (Huawei me906e).
Huawei firmwares will dynamically assign interface numbers. Functions
are renumbered when the firmware is reconfigured.
Fix by changing the DEVICE_HWI type to use a simplified version
of Huawei's subclass + protocol scheme: Blacklisting known network
interface combinations and assuming the rest are serial.

Here are a collection of small fixes tha have been gathered for
4.4-rc1. The only significant changes are those in PCI drivers
Kconfig, to use "depends on" instead of "select" for CONFIG_ZONE_DMA.
A reverse select is often more user-friendly, but in this case, it
makes hard to manage with the conflict with ZONE_DEVICE, so changed in
such a way for now.
Others are all small fixes and quirks: an error check in soundcore
reigster_chrdev(), HD-audio HDMI/DP phantom jack fix, Intel Broxton DP
quirk, USB-audio DSD device quirk, some constifications, etc.

ARC: cpu_relax() to be compiler barrier even for UP
ARC: use ASL assembler mnemonic
ARC: [arcompact] Handle bus error from userspace as Interrupt not exception
ARC: remove extraneous header include
ARCv2: lib: memcpy: use local symbols
cpu_relax() on ARC has been barrier only for SMP (and no-op for UP). Per
recent discussions, it is safer to make it a compiler barrier
unconditionally.

ARCompact and ARCv2 only have ASL, while binutils used to support LSL as
a alias mnemonic.
Newer binutils (upstream) don't want to do that so replace it.
Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
Bus errors from userspace on ARCompact based cores are handled by core
as a high priority L2 interrupt but current code treated it as interrupt
Handling an interrupt like exception is certainly not going to go unnoticed.
(and it worked so far as we never saw a Bus error from userspace until
IPPK guys tested a DDR controller with ECC error detection etc hence
needed to explicitly trigger/handle such errors)
- So move mem_service exception handler from common code into ARCv2 code.
- In ARCompact code, define mem_service as L2 interrupt handler which
just drops down to pure kernel mode and goes of to enqueue SIGBUS

Here's the branch of chrome platform changes for v4.4. Some have been queued
up for the full 4.3 release cycle since I forgot to send them in for that
round (rebased early on to deal with fixes conflicts).
Most of these enable EC communication stuff -- Pixel 2015 support, enabling
building for ARM64 platforms, and a few fixes for memory leaks.
There's also a patch in here to allow reading/writing the verified boot
context, which depends on a sysfs patch acked by Greg.

Pull SCSI target updates from Nicholas Bellinger:
"This series contains HCH's changes to absorb configfs attribute
->show() + ->store() function pointer usage from it's original
tree-wide consumers, into common configfs code.
It includes usb-gadget, target w/ drivers, netconsole and ocfs2
changes to realize the improved simplicity, that now renders the
original include/target/configfs_macros.h CPP magic for fabric drivers
and others, unnecessary and obsolete.
And with common code in place, new configfs attributes can be added
easier than ever before.
Note, there are further improvements in-flight from other folks for
v4.5 code in configfs land, plus number of target fixes for post -rc1
code"

through the char/misc tree in commit 7bd1d4093c ("stm class: Introduce
an abstraction for System Trace Module devices").
This merge resolution comes from Alexander Shishkin, who updated his stm
class tracing abstraction to account for the removal of the old
show_attribute and store_attribute methods in commit 517982229f
("configfs: remove old API") from this pull. As Alexander says about
that patch:
"There's no need to keep an extra wrapper structure per item and the
awkward show_attribute/store_attribute item ops are no longer needed.
This patch converts policy code to the new api, all the while making
the code quite a bit smaller and easier on the eyes.
