USB: serial: handle Data Carrier Detect changes

2011-01-23T02:53:26+00:00

Alan's commit 335f8514f200e63d689113d29cb7253a5c282967 introduced
.carrier_raised function in several drivers.  That also means
tty_port_block_til_ready can now suspend the process trying to open the serial
port when Carrier Detect is low and put it into tty_port.open_wait queue.  We
need to wake up the process when Carrier Detect goes high and trigger TTY
hangup when CD goes low.

Some of the devices do not report modem status line changes, or at least we
don't understand the status message, so for those we remove .carrier_raised
again.

USB: gadget: Fix endpoint representation in ci13xxx_udc

2011-01-23T02:49:24+00:00

Fix a bug where only half the number of endpoints supported by the
hardware are exposed to gadget.  If DEN filed in the DCCPARAMS
register has 'N' then 'N' IN endpoints and 'N" OUT endpoints can be
supported.  But only 'N' bidirectional endpoints are added to the
gadget ep_list.  This patch also ensures that the data and handshake
transactions of previous setup packet are flushed upon a new setup
packet arrival on ep0.

USB: gadget: Fix error path in ci13xxx_udc gadget probe function

2011-01-23T02:49:02+00:00

Don't call gadget driver's unbind when bind is failed.  Initialize
udc->driver only after gadget driver bind is successful.  Otherwise
pull-up can be enabled upon VBUS session even when no gadget is
bounded.

USB: serial: Updated support for ICOM devices

2011-01-23T02:48:10+00:00

I found the original patch on the db0fhn repeater wiki (couldn't find the email
of the origial author) I guess it was never commited.
I updated and added some Icom HAM-radio devices to the ftdi driver.
Added extra comments to make clear what devices it are.

drivers: update to pl2303 usb-serial to support Motorola cables

2011-01-23T02:44:38+00:00

Added 0x0307 device id to support Motorola cables to the pl2303 usb
serial driver. This cable has a modified chip that is a pl2303, but
declares itself as 0307. Fixed by adding the right device id to the
supported devices list, assigning it the code labeled
PL2303_PRODUCT_ID_MOTOROLA.
