a5b4466d33 usb: dwc3: Add support to select maximum speed via extcon notification
Use extcon notification to select the maximum speed for host as well
as for peripheral mode. Notification handler sets maximum speed based
on the extcon cable state flag. This provides an option to start host
or peripheral in high speed only mode and leave ss phy suspended.

This change reverts Commit f3af36511e ("usb: dwc3: gadget: always
enable IOC on bulk/interrupt transfers") which sets IOC bit for both
bulk/interrupt transfers resulting into interrupt for each TRB
completion with event as XFERINPROGRESS. In some cases it has been
observed that controller is not able to complete provided TRB on
bulk-in endpoint causing stall conditions. Hence Fix this issue by not
setting IOC bit for each TRB to receive XFERCOMPLETE interrupt with it.

94a976091c dwc3: gadget: Avoid starting next transfer if transfer is active
XFERNOTREADY event provides status about current transfer. Hence
if transfer is active, then avoid starting next transfer by calling
__dwc3_gadget_kick_transfer() API. Otherwise USB controller stalls to
perform data transfer on that endpoint due to starting new transfer
without completing in progress transfer.

This reverts commit 6bb4fe12ea
("usb: dwc3: gadget: use update transfer command"). If we get
a Xfer Not Ready event with reason "Transfer Active" issuing
update transfer for the endpoint for any pending request
results into transfer stall on the endpoint. Hence do not use
update transfer command for on-demad transfers.

commit c7de573471832dff7d31f0c13b0f143d6f017799 upstream.

When using SG lists, we would end up setting

	num_mapped_sgs * (request->length - count)

Let's fix that up by incrementing request->actual
only once.

commit 9cad39fe4e4a4fe95d8ea5a7b0692b0a6e89e38b upstream.

commit f3af36511e ("usb: dwc3: gadget: always

regressing Isochronous endpoints by clearing
DWC3_EP_BUSY flag too early, which resulted in
choppy audio playback over USB.

Fix that by partially reverting original commit and
making sure that we check for isochronous endpoints.

ffedac1717 usb: dwc3-msm: Only set vbus_draw for SDP type
When gadget driver sets VBUS current draw, this should
only be applicable if the charger type is SDP. For
other downstream types, such as CDP, it can draw up up
to the maximum (1.5A) without having to follow the rules of
configured/suspended current limits. Further, with Power
Delivery role swap supported, it's possible the gadget (UFP)
is a power source, so vbus_draw() should be no-op'ed.

1cb5c91b99 usb: dwc3: Remove tasklet bottom half handler
There is a possibility of tasklet bottom half handler racing
with dwc3_msm_suspend(). As a result before disabling the dwc3
irq, dwc3 interrupts are fired and once the suspend routine
disables the clocks bottom half handler gets a chance to run
and tries to access dwc3 register resulting into un-clocked
register access. Since dwc3 interrupt is already running in
threaded irq context, interrupt can be directly handled in
same context and avoid this race.

c24e9fe614 usb: dwc3: Fix NULL ptr dereference in ep disable ops
In RNDIS composition when windows PC is suspended RNDIS
driver sends flow control enable which frees the trb pool
of the RNDIS endpoints and trb pool pointer is set to NULL.
When bus suspend happens RNDIS gsi driver performs endpoint
disable operation because remote wake up is disabled. Endpoint
disable perform memset 0 on trb pool which is already set to
NULL causing the NULL pointer dereference. Fix this by adding
NULL check for trb pool before doing memset 0.

4d0a155ed7 usb: dwc3: Determine connection speed for HS PHY
DP/DM linestate is needed by the QUSB2 PHY driver to configure the
polarity of DP/DM transition triggers for exiting low power mode.
This was previously available via the  QUSB2PHY_PORT_UTMI_STATUS
PHY register which is now deprecated. In order to correctly determine
the interrupt polarity we need to pass the current operating speed
to the QUSB2 PHY driver. The PHY driver uses mode, speed and
cable connection status to determine the linestate and configure
interrupt polarities for wake up. Add logic to determine operating
speed for host and device mode cases.

endpoints are less than DWC3_TRB_NUM. This results in
to memory corruption. Fix this bug by introducing
num_trbs member in dwc3_ep structure to save number of
trbs allocated in a dma pool upon dma pool creation.
Ep disable operation will use num_trbs of a dwc3_ep to
perform memset 0.

36fc1c1e29 usb: dwc3: exynos: Fix deferred probing storm.
commit 4879efb34f7d49235fac334d76d9c6a77a021413 upstream.

dwc3-exynos has two problems during init if the regulators are slow
to come up (for instance if the I2C bus driver is not on the initramfs)
and return probe deferral. First, every time this happens, the driver
leaks the USB phys created; they need to be deallocated on error.

Second, since the phy devices are created before the regulators fail,
this means that there's a new device to re-trigger deferred probing,
which causes it to essentially go into a busy loop of re-probing the
device until the regulators come up.

Move the phy creation to after the regulators have succeeded, and also
fix cleanup on failure. On my ODROID XU4 system (with Debian's initramfs
which doesn't contain the I2C driver), this reduces the number of probe
attempts (for each of the two controllers) from more than 2000 to eight.

197598e593 usb: dwc3: Change dwc3 irq to oneshot threaded irq
There is a possibility of dwc3 irq being fired as soon as
it gets enabled by tasklet handler. As a result dwc3 hard irq
handler disables the irq and schedules tasklet. If tasklet is
still running, tasklet_schedule becomes no op and dwc3 irq
remains disabled permanently. Fix this issue by handling irq
in threaded context with IRQF_ONESHOT flag set. Also update
the shared irq flag in xhci platform driver for irq registration
in HCD driver.

15fb7f86a0 usb: gadget: Use mult as 3 for GSI related USB IN endpoint always
Interfaces like MBIM or ECM is having multiple data interfaces.
In this case, SET_CONFIG() happens before set_alt with data interface 1.
Due to this, TXFIFO of GSI IN endpoint is not resized causing low
throughput in DL direction. Fix this issue by using mult as 3 for
GSI related USB IN endpoint irrespective of super-speed or high-speed
mode.

99cc257e08 Revert "usb: dwc3: core: only setting the dma_mask when needed"
commit 19bacdc925 ("usb: dwc3: core: only setting the
dma_mask when needed") does not allow to modify dma mask if it
is already set. Since the platform device has default 32-bit
dma mask set change prevents to update the dma mask to 64-bit.
This leads to kernel panic due to out of SW-IOMMU space when a
function driver tries to map more than 32-bit wide address.

2142069a88 usb: dwc3: Fix extcon notification for non-type-c usb cable
In case of non-type-c usb cable extcon cable state for
EXTCON_USB_CC returns error and driver bails out. This
causes usb enumeration failure. Hence set the typec_orientation
to ORIENTATION_NONE and continue with usb enumeration.
In case of super speed mode with type-c usb cable even if extcon
cable state return error for EXTCON_USB_CC then also usb device
will get enumerated falling back to high speed mode.

e89026c0e2 usb: dwc3: Add support handle type-c plug orientation
Register callbacks for plug orientations in order to
cache the current plug orientation reported by extcon.
This allows super speed phy driver to configure the
appropriate lane upon phy initialization.

4a09bafb4c USB: dwc3: debugfs: Add boundary check in dwc3_store_ep_num()
User can pass arguments as part of write to requests and endpoint number
will be calculated based on the arguments. There is a chance that driver
can access ep structue that is not allocated due to invalid arguments
passed by user. Hence fix the issue by having check and return error in
case of invalid arguments.

a75c7c67bd usb: gadget: Iterate over all IN EPs for allocation of TX FIFOs
GSI EPs are assigned to the last 2 IN EPs. While allocating
the TX FIFO sizes we need to iterate over all IN EPs to correctly
allocate larger TX FIFOs for GSI accelerated endpoints.
Update the logic from using min_t(int, dwc->num_in_eps,
cdev->config->num_ineps_used + 1) to just use dwc->num_in_eps.
The EPs that are not enabled will be given the default TX FIFO
size while the ones that are enabled are given TX FIFO sizes
based on the burst size configured for that EP.

d8179dff9e usb: dwc3: Fix dep name handling upon ep disable
dep name needs to be updated only for non-gsi endpoints
since gsi endpoints are statically assigned. Due to merge
from previous kernel dep name is updated twice upon ep
disable. This is causing gsi ep names to get modified
resulting into failure in finding the original gsi ep name
upon function bind. Hence update the dep name only once
at the end of ep disable and skip it for gsi eps.

f217c8f353 usb: dwc3: Add support for gsi endpoint disable operation
gsi driver does not call the gadget API usb_ep_enable()
instead uses gsi ep operation call back to enable gsi ep.
As a result ep->enabled flag remains clear. Later function
driver calls usb_ep_disble() API from gadget framework and
ep disable operation gets skipped. Fix this by adding gsi ep
operation for ep disable. This makes the enable and
disable ep operations both handled by gsi ep ops.

32592a9660 dwc3: Enable and disable core IRQ from dwc3 suspend/resume only
dwc3 core IRQ's depth (disable depth) is going out of sync due to
disabling it from dwc3's state machine when there are multiple
time USB composition switch is being performed before USB cable
connect. Linux IRQ framework doesn't decrement disable depth
count with enable_irq() when IRQ is enabled previously but it does
increment disable depth every time disable_irq() is called. This
results into dwc3 core IRQ to remain disable causing USB enumeration
failure as unknown device due to USB controller driver is not
seeing any of RESET and CONNECT DONE interrupt although USB controller
has posted those events into event buffer. Fix this issue by
making sure that USB core IRQ is disabled by default, and
enable/disable it from dwc3 suspend/resume only.

606410ceac usb: dwc3: Request dwc3 irq in driver probe
request_irq() for dwc irq is called in dwc3_gadget_start()
when msm-dwc3 is in suspended state because usb cable is not
connected. dwc3 resume happens upon USB connect, it enables
already enabled irq. This result into unbalanced enable irq
warning. Fix this by moving request_irq to dwc3_probe().

29a79eb7ca dwc3-msm: Don't perform bus voting from dwc3 driver probe
Currently dwc3 driver's probe is doing bus voting. This voting remains
until USB cable is connected and disconnected. Due to this voting, XOSD
is not happening. Fix this issue by removing voting from driver's probe
context and let USB's suspend and resume take care of bus unvoting and
voting respectively.
