Policy engine receives an alert message in PD 3.0 SINK ready
state and caches alert data object. It sends Get_Status to receive
status information from port partnet to check for alert specific
changes. Once status information is received send uevent to
notify the same. This message is recommended to be supported
by PD 3.0 SINK.

Send following two control messages using sysfs in SINK
ready state and cache response:-
1) Get_Source_Cap_Extended and Source_Capabilities_Extended
as response
2) Get_PPS_Status and PPS_Status as response.
These two control messages are recommended for PD 3.0 SINK.

PD 3.0 requires the Not Supported message to be sent after
receiving a message that is not supported. Add this to both
PE_SNK_READY and PE_SRC_READY states when there is an
unhandled message. If 3.0 sink-only mode is enabled, also
disallow PR_SWAP, VCONN_SWAP, and GET_SOURCE_CAP, so that the
state machine can fall through to responding with Not Supported.

Add support for receiving extended messages. Since the underlying
PD PHY only supports a fixed 30 byte payload, longer messages up
to 260 bytes must use chunking, which requires the receiver to request
the next chunk until the entire payload is delivered.
When receiving a chunk, call a helper from phy_msg_received() to stage
the received bytes into a long rx_msg and queue a request for the
next chunk. Refactor struct rx_msg to use a flexible array member to
accommodate the larger potential sizes.
Finally, add new enum definitions for the new PD 3.0 message types.

In this case gsi_ctrl_clear_cpkt_queues function is called
which is holding spinlock and in the meantime dwc3_interrupt
occurred on same CPU which in turn is calling gsi_ctrl_clear_cpkt_queues
function and it is trying to acquire the same spinlock causing
deadlock.
This change disables the interrupts when spinlock is acquired
in gsi_ctrl_clear_cpkt_queues function.

DWC3 driver uses wakeup_source and allows pm_suspend only after
entering low power mode as part of runtime suspend. This prevents
PM suspend in host mode if connected device's driver doesn't
support runtime or selective suspend.
Add support in driver where user can specify using dtsi attribute
to not use wakeup source in host mode. It will allow system to enter
deep sleep or pm_suspend irrespective of runtime PM state of XHCI.
On high level below are the changes in default behavior:
-Do not use wakeup_source for DWC3 when operating in host mode.
-For host mode, devices will suspend upon PM suspend and resumed
after PM resume.

Currently we allocate IPC log buffer when instance is created,
and free IPC log buffer when instance is freed.
So we can't get IPC log when issue happens after the instance
is freed.
Move IPC log buffer allocate and free to module init and exit.

Currently driver is enabling hsphy_irq and ssphy_irq at the end
of dwc3_msm_suspend() without any spinlock/mutex protection. But
if it happens that hsphy_irq or ssphy_irq gets fired right after
enablement of irqs, there is a chance that we might see warnings
related to unbalanced irq enable. This could happen due to flag
is not yet set to indicate phy irqs enabled in suspend(). This
might cause phy irq left enabled after resume and could cause
crash due to unclocked access in host mode. Fix the unbalance irq
enable by having mutex protection and also extend mutex protection
for dwc3_msm_suspend() and dwc3_msm_resume().

composite driver is using sprintf() function to expose value to
userspace. This sprintf() is banned function and instead required
to use snprintf() function. Hence replace sprintf() with snprintf()
function to fix static analysis tool error.

This allows Host to load NDIS 6.0 driver for RNDIS over ethernet.
Design objectives of NDIS 6.0 is to enhance driver performance
and scalability. Observing higher peak tput (308Mbps --> 480Mbps)
for FTP transfer on live network. It resolves the data stall that
is being caused by the sudden transfer abort coming from the NDIS
5.0 Host driver.

commit ed18c5fa945768a9bec994e786edbbbc7695acf6 upstream.
This optimization significantly reduces xhci driver load time.
In ACPI tables the acpi companion port devices are children of
the hub device. The port devices are identified by their port number
returned by the ACPI _ADR method.
_ADR 0 is reserved for the root hub device.
The current implementation to find a acpi companion port device
loops through all acpi port devices under that parent hub, evaluating
their _ADR method each time a new port device is added.
for a xHC controller with 25 ports under its roothub it
will end up invoking ACPI bytecode 625 times before all ports
are ready, making it really slow.
The _ADR values are already read and cached earler. So instead of
running the bytecode again we can check the cached _ADR value first,
and then fall back to the old way.
As one of the more significant changes, the xhci load time on
Intel kabylake reduced by 70%, (28ms) from
initcall xhci_pci_init+0x0/0x49 returned 0 after 39537 usecs
to
initcall xhci_pci_init+0x0/0x49 returned 0 after 11270 usecs

If the request->length is zero, a ZLP should already be sent due to that
and another ZLP is not needed to terminate the transfer.

So far, dwc3 has always missed request->zero
handling for every endpoint. Let's implement
that so we can handle cases where transfer must
be finished with a ZLP.
Note that dwc3 is a little special. Even though
we're dealing with a ZLP, we still need a buffer
of wMaxPacketSize bytes; to hide that detail from
every gadget driver, we have a preallocated buffer
of 1024 bytes (biggest bulk size) to use (and
share) among all endpoints.

The req->complete seems to presist the callback pointer for
the control requests. This causes the serial of the accessory
to be overridden when an accessory function specific out
control request is issued right after the ACCESSORY_SEND_STRING
control request. Therefore, assign a no-op req complete function
when nothing needs to be done once the request is completed.

There's a race between usb_gadget_udc_stop() which is likely
to set the gadget driver to NULL in the udc driver and this drivers
gadget disconnect fn which likely checks for the gadget driver to
a null ptr. It happens that unbind (doing set_gadget_data(NULL))
is called before the gadget driver is set to NULL and the udc driver
calls disconnect fn which results in cdev being a null ptr.
As a workaround we check cdev in android_disconnect() to prevent
the following panic:

unplug and plug in again the usb connector which causes the change
from device to host and back to device mode.

commit e788787ef4f9c24aafefc480a8da5f92b914e5e6 upstream.
Certain HP keyboards would keep inputting a character automatically which
is the wake-up key after S3 resume
On some AMD platforms USB host fails to respond (by holding resume-K) to
USB device (an HP keyboard) resume request within 1ms (TURSM) and ensures
that resume is signaled for at least 20 ms (TDRSMDN), which is defined in
USB 2.0 spec. The result is that the keyboard is out of function.
In SNPS USB design, the host responds to the resume request only after
system gets back to S0 and the host gets to functional after the internal
HW restore operation that is more than 1 second after the initial resume
request from the USB device.
As a workaround for specific keyboard ID(HP Keyboards), applying port reset
after resume when the keyboard is plugged in.

commit 7496cfe5431f21da5d27a8388c326397e3f0a5db upstream.
Moshi USB to Ethernet Adapter internally uses a Genesys Logic hub to
connect to Realtek r8153.
The Realtek r8153 ethernet does not work on the internal hub, no-lpm quirk
can make it work.
Since another r8153 dongle at my hand does not have the issue, so add
the quirk to the Genesys Logic hub instead.

commit 2eac13624364db5b5e1666ae0bb3a4d36bc56b6e upstream.
While unlink an urb, if the urb has been programmed in the controller,
the controller driver might do some hw related actions to tear down the
urb.
Currently usb_hcd_flush_endpoint() passes each urb from the head of the
endpoint's urb_list to the controller driver, which could make the
controller driver think each urb has been programmed and take the
unnecessary actions for each urb.
This patch changes the behavior in usb_hcd_flush_endpoint() to pass the
urbs from the tail of the list, to avoid any unnecessary actions in an
controller driver.

commit 94c43b9897abf4ea366ed4dba027494e080c7050 upstream.
Some buggy USB disk adapters disconnect and reconnect multiple times
during the enumeration procedure. This may lead to a device
connecting at full speed instead of high speed, because when the USB
stack sees that a device isn't able to enumerate at high speed, it
tries to hand the connection over to a full-speed companion
controller.
The logic for doing this is careful to check that the device is still
connected. But this check is inadequate if the device disconnects and
reconnects before the check is done. The symptom is that a device
works, but much more slowly than it is capable of operating.
The situation was made worse recently by commit 22547c4cc4fe ("usb:
hub: Wait for connection to be reestablished after port reset"), which
increases the delay following a reset before a disconnect is
recognized, thus giving the device more time to reconnect.
This patch makes the check more robust. If the device was
disconnected at any time during enumeration, we will now skip the
full-speed handover.

commit cd5a6a4fdaba150089af2afc220eae0fef74878a upstream.
Make usb_hc_died() clear the HCD_FLAG_RH_RUNNING flag for the shared
HCD and set HCD_FLAG_DEAD for it, in analogy with what is done for
the primary one.
Among other thigs, this prevents check_root_hub_suspended() from
returning -EBUSY for dead HCDs which helps to work around system
suspend issues in some situations.
This actually fixes occasional suspend failures on one of my test
machines.

commit 45d73860530a14c608f410b91c6c341777bfa85d upstream.
commit 68fe05e2a451 ("usb: musb: fix tx fifo flush handling") drops the
1ms delay trying to solve the long disconnect time issue when
application queued many tx urbs. However, the 1ms delay is needed for
some use cases, for example, without the delay, reconnecting AR9271 WIFI
dongle no longer works if the connection is dropped from the AP.
So let's add back the 1ms delay in musb_h_tx_flush_fifo(), and solve the
long disconnect time problem with a separate patch for
usb_hcd_flush_endpoint().

If glue driver's probe failed, it tries to remove child devices
as part of of_platform_depopulate during cleanup. This results in
calling dwc3 core platform device's remove callback dwc3_remove().
This function is calling phy_set_suspend() for both HSPHY and SSPHY
to suspend them. But it is resulting in crash due to unclocked access.
Remove those calls, which are not required as glue driver will take
care of suspend/resume PHYs.

Update the TUNE2 parameter by adjusting the programmed tune2 value
with the correction value, if mentioned in dtsi to improve rise/fall times.
In case efuse register value is zero after correction, write previous TUNE2
register value as it is instead of writing hardcoded value. And correction
value should be between [-10 5] in order to take into consideration while
updating TUNE2 register with fused value.

Add some delay between two consecutive register reads in while loop
so that to avoid traffic congestion on NOCs.

lfps_rxterm interrupt is not seen on attaching USB super speed device when
USB is into LPM with USB host mode without device attach case. This change
fixes below issues to get lfps_rxterm interrupt to resume USB.
1. Correct polarity of lfps rxterm interrupt from edge trigger to level
trigger
2. Notify USB SS PHY driver about USB host cable status to allow required
configuration while USB SS PHY is being suspended.
3. Also it is required to clear ALFPS_DTCT_EN and set ARCVR_DTCT_EVENT_SEL
when USB SS PHY is being suspended with host cable connected case to detect
next super speed device attach condition using lfps_rxterm interrupt.

Remove the timeout_ms parameter as this can be part of the
function implementation itself. Define tReceiverResponse (15ms)
for message writes which is a reasonable value to allow for
up to 3 retries without receiving GoodCRC before determining
the send failed. On successful transmission simply return 0
to unburden the caller from having to check against the
data_len param.
For signals set the timeout as tHardResetComplete (5ms).
