USB: add new zte 3g-dongle's pid to option.c

2012-02-13T19:17:04+00:00

commit 1608ea5f4b5d6262cd6e808839491cfb2a67405a upstream.

As ZTE have and will use more pid for new products this year,
so we need to add some new zte 3g-dongle's pid on option.c ,
and delete one pid 0x0154 because it use for mass-storage port.

usb: Skip PCI USB quirk handling for Netlogic XLP

2012-02-13T19:17:03+00:00

commit e4436a7c17ac2b5e138f93f83a541cba9b311685 upstream.

The Netlogic XLP SoC's on-chip USB controller appears as a PCI
USB device, but does not need the EHCI/OHCI handoff done in
usb/host/pci-quirks.c.

The pci-quirks.c is enabled for all vendors and devices, and is
enabled if USB and PCI are configured.

If we do not skip the qurik handling on XLP, the readb() call in
ehci_bios_handoff() will cause a crash since byte access is not
supported for EHCI registers in XLP.

usb: gadget: zero: fix bug in loopback autoresume handling

2012-02-13T19:17:03+00:00

commit 683da59d7b8ae04891636d4b59893cd4e9b0b7e5 upstream.

ab943a2e125b (USB: gadget: gadget zero uses new suspend/resume hooks)
introduced a copy-paste error where f_loopback.c writes to a variable
declared in f_sourcesink.c. This prevents one from creating gadgets
that only have a loopback function.

USB: cp210x: initialise baud rate at open

commit cdc32fd6f7b2b2580d7f1b74563f888e4dd9eb8a upstream.

The newer cp2104 devices require the baud rate to be initialised after
power on. Make sure it is set when port is opened.

commit be125d9c8d59560e7cc2d6e2b65c8fd233498ab7 upstream.

We do not implement B0 hangup yet so map low baudrates to 300bps.

USB: cp210x: fix CP2104 baudrate usage

2012-02-03T17:22:23+00:00

commit 7f482fc88ac47662228d6b1f05759797c8936a30 upstream.

This fix changes the way baudrates are set on the CP210x devices from
Silicon Labs. The CP2101/2/3 will respond to both a GET/SET_BAUDDIV
command, and GET/SET_BAUDRATE command, while CP2104 and higher devices
only respond to GET/SET_BAUDRATE. The current cp210x.ko driver in
kernel version 3.2.0 only implements the GET/SET_BAUDDIV command.

This patch implements the two new codes for the GET/SET_BAUDRATE
commands. Then there is a change in the way that the baudrate is
assigned or retrieved. This is done according to the CP210x USB
specification in AN571. This document can be found here:
http://www.silabs.com/pages/DownloadDoc.aspx?FILEURL=Support%20Documents/TechnicalDocs/AN571.pdf&src=DocumentationWebPart

Sections 5.3/5.4 describe the USB packets for the old baudrate method.
Sections 5.5/5.6 describe the USB packets for the new method. This
patch also implements the new request scheme, and eliminates the
unnecessary baudrate calculations since it uses the "actual baudrate"
method.

This patch solves the problem reported for the CP2104 in bug 42586,
and also keeps support for all other devices (CP2101/2/3).

This patchfile is also attached to the bug report on
bugzilla.kernel.org. This patch has been developed and test on the
3.2.0 mainline kernel version under Ubuntu 10.11.
