usb: host: ehci-sys: delete useless bus_to_hcd conversion

2015-10-28T02:14:42+00:00

[ Upstream commit 0521cfd06e1ebcd575e7ae36aab068b38df23850 ]

The ehci platform device's drvdata is the pointer of struct usb_hcd
already, so we doesn't need to call bus_to_hcd conversion again.

usb: dwc3: ep0: Fix mem corruption on OUT transfers of more than 512 bytes

2015-10-28T02:14:42+00:00

[ Upstream commit b2fb5b1a0f50d3ebc12342c8d8dead245e9c9d4e ]

DWC3 uses bounce buffer to handle non max packet aligned OUT transfers and
the size of bounce buffer is 512 bytes. However if the host initiates OUT
transfers of size more than 512 bytes (and non max packet aligned), the
driver throws a WARN dump but still programs the TRB to receive more than
512 bytes. This will cause bounce buffer to overflow and corrupt the
adjacent memory locations which can be fatal.

Fix it by programming the TRB to receive a maximum of DWC3_EP0_BOUNCE_SIZE
(512) bytes.

USB: symbolserial: Use usb_get_serial_port_data

2015-10-28T02:14:40+00:00

[ Upstream commit 951d3793bbfc0a441d791d820183aa3085c83ea9 ]

The driver used usb_get_serial_data(port->serial) which compiled but resulted
in a NULL pointer being returned (and subsequently used). I did not go deeper
into this but I guess this is a regression.

These two headphones need a reset-resume quirk to properly resume to
original volume level.

usb: Add device quirk for Logitech PTZ cameras

2015-10-28T02:14:08+00:00

[ Upstream commit 72194739f54607bbf8cfded159627a2015381557 ]

Add a device quirk for the Logitech PTZ Pro Camera and its sibling the
ConferenceCam CC3000e Camera.
This fixes the failed camera enumeration on some boot, particularly on
machines with fast CPU.

Tested by connecting a Logitech PTZ Pro Camera to a machine with a
Haswell Core i7-4600U CPU @ 2.10GHz, and doing thousands of reboot cycles
while recording the kernel logs and taking camera picture after each boot.
Before the patch, more than 7% of the boots show some enumeration transfer
failures and in a few of them, the kernel is giving up before actually
enumerating the webcam. After the patch, the enumeration has been correct
on every reboot.

usb: musb: cppi41: allow it to work again

2015-10-28T02:14:07+00:00

[ Upstream commit b0a688ddcc5015eb26000c63841db7c46cfb380a ]

since commit 33c300cb90a6 ("usb: musb: dsps:
don't fake of_node to musb core") we have been
preventing CPPI 4.1 from probing due to NULL
of_node. We can't revert said commit otherwise
a different regression would show up, so the fix
is to look for the parent device's (glue layer's)
of_node instead, since that's the thing which
is actually described in DTS.

usb: Use the USB_SS_MULT() macro to get the burst multiplier.

2015-10-28T02:14:06+00:00

[ Upstream commit ff30cbc8da425754e8ab96904db1d295bd034f27 ]

Bits 1:0 of the bmAttributes are used for the burst multiplier.
The rest of the bits used to be reserved (zero), but USB3.1 takes bit 7
into use.

Use the existing USB_SS_MULT() macro instead to make sure the mult value
and hence max packet calculations are correct for USB3.1 devices.

Note that burst multiplier in bmAttributes is zero based and that
the USB_SS_MULT() macro adds one.

usb: chipidea: udc: using the correct stall implementation

2015-10-28T02:14:05+00:00

[ Upstream commit 56ffa1d154c7e12af16273f0cdc42690dd05caf5 ]

According to spec, there are functional and protocol stalls.

For functional stall, it is for bulk and interrupt endpoints,
below are cases for it:
- Host sends SET_FEATURE request for Set-Halt, the udc driver
needs to set stall, and return true unconditionally.
- The gadget driver may call usb_ep_set_halt to stall certain
endpoints, if there is a transfer in pending, the udc driver
should not set stall, and return -EAGAIN accordingly.
These two kinds of stall need to be cleared by host using CLEAR_FEATURE
request (Clear-Halt).

For protocol stall, it is for control endpoint, this stall will
be set if the control request has failed. This stall will be
cleared by next setup request (hardware will do it).

It fixed usbtest (drivers/usb/misc/usbtest.c) Test 13 "set/clear halt"
test failure, meanwhile, this change has been verified by
USB2 CV Compliance Test and MSC Tests.

usb: xhci: Add support for URB_ZERO_PACKET to bulk/sg transfers

[ Upstream commit 4758dcd19a7d9ba9610b38fecb93f65f56f86346 ]

This commit checks for the URB_ZERO_PACKET flag and creates an extra
zero-length td if the urb transfer length is a multiple of the endpoint's
max packet length.
