USB: serial: mos7840: Fixed MCS7820 device attach problem

2012-04-02T17:31:36+00:00

commit 093ea2d3a766cb8a4c4de57efec6c0a127a58792 upstream.

A MCS7820 device supports two serial ports and a MCS7840 device supports
four serial ports. Both devices use the same driver, but the attach function
in driver was unable to correctly handle the port numbers for MCS7820
device. This problem has been fixed in this patch and this fix has been
verified on x86 Linux kernel 3.2.9 with both MCS7820 and MCS7840 devices.

usb: cp210x: Update to support CP2105 and multiple interface devices

2012-04-02T17:31:36+00:00

commit a5360a53a7ccad5ed9ccef210b94fef13c6e5529 upstream.

This patch updates the cp210x driver to support CP210x multiple
interface devices devices from Silicon Labs. The existing driver
always sends control requests to interface 0, which is hardcoded in
the usb_control_msg function calls. This only allows for single
interface devices to be used, and causes a bug when using ports on an
interface other than 0 in the multiple interface devices.

Here are the changes included in this patch:
- Updated the device list to contain the Silicon Labs factory default
  VID/PID for multiple interface CP210x devices
- Created a cp210x_port_private struct created for each port on
  startup, this struct holds the interface number
- Added a cp210x_release function to clean up the cp210x_port_private
  memory created on startup
- Modified usb_get_config and usb_set_config to get a pointer to the
  cp210x_port_private struct, and use the interface number there in the
  usb_control_message wIndex param

USB: qcserial: don't grab QMI port on Gobi 1000 devices

2012-04-02T17:31:36+00:00

commit c192c8e71a2ded01170c1a992cd21aaedc822756 upstream.

Gobi 1000 devices have a different port layout, which wasn't respected
by the current driver, and thus it grabbed the QMI/net port.  In the
near future we'll be attaching another driver to the QMI/net port for
these devices (cdc-wdm and qmi_wwan) so make sure the qcserial driver
doesn't claim them.  This patch also prevents qcserial from binding to
interfaces 0 and 1 on 1K devices because those interfaces do not
respond.

USB: serial: fix console error reporting

2012-04-02T17:31:35+00:00

commit 548dd4b6da8a8e428453d55f7fa7b8a46498d147 upstream.

Do not report errors in write path if port is used as a console as this
may trigger the same error (and error report) resulting in a loop.

USB: ftdi_sio: add support for FT-X series devices

2012-04-02T17:31:32+00:00

commit dc0827c128c0ee5a58b822b99d662b59f4b8e970 upstream.

Add PID 0x6015, corresponding to the new series of FT-X chips
(FT220XD, FT201X, FT220X, FT221X, FT230X, FT231X, FT240X).  They all
appear as serial devices, and seem indistinguishable except for the
default product string stored in their EEPROM.  The baudrate
generation matches FT232RL devices.

Tested with a FT201X and FT230X at various baudrates (100 - 3000000).

USB: Microchip VID mislabeled as Hornby VID in ftdi_sio.

2012-04-02T17:31:32+00:00

commit c1cee1d84001815a1b4321c49b995254c0df3100 upstream.

Microchip VID (0x04d8) was mislabeled as Hornby VID according to USB-IDs.

A Full Speed USB Demo Board PID (0x000a) was mislabeled as
Hornby Elite (an Digital Command Controller Console for model railways).

Most likely the Hornby based their design on
PIC18F87J50 Full Speed USB Demo Board.

USB: ftdi_sio: add support for BeagleBone rev A5+

commit 444aa7fa9bd752d19ce472d3e02558b987c3cc67 upstream.

BeagleBone changed to the default FTDI 0403:6010 id in rev A5 to make life
easier for Windows users, so we need a similar workaround as the Calao
board to support it.
