USB: serial: handle Data Carrier Detect changes

2011-03-21T19:45:47+00:00

commit d14fc1a74e846d7851f24fc9519fe87dc12a1231 upstream.

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.

Fix usb_serial_probe() problem introduced by the recent kfifo changes

2009-12-23T16:53:31+00:00

The USB serial code was a new user of the kfifo API, and it was missed
when porting things to the new kfifo API.

Please make the write_fifo in place.  Here is my patch to fix the
regression and full ported version.

usb_serial: Kill port mutex

2009-12-11T23:18:04+00:00

The tty port has a port mutex used for all the port related locking so we
don't need the one in the USB serial layer any more.

USB OTG: Add generic driver for ULPI OTG transceiver

2009-12-11T19:55:16+00:00

This adds a minimal generic driver for ULPI connected transceivers,
using the OTG framework functions recently introduced.

The driver got a table to match the ULPI chips, which currently only has
one entry for NXP's ISP 1504 transceiver.

USB OTG: add support for ulpi connected external transceivers

2009-12-11T19:55:16+00:00

This adds support for OTG transceivers directly connected to the ULPI
interface. In particular, the following details are added

- a struct for low level io functions (read/write)
- a priv field to be used as 'viewport' by low level access functions
- an (*init) and (*shutdown) callbacks, along with static inline helpers
- a (*set_vbus) callback to switch the port power on and off
- a flags field for per-transceiver settings
- some defines for the flags bitmask to configure platform specific
  details

USB gadget: Handle endpoint requests at the function level

2009-12-11T19:55:15+00:00

Control requests targeted at an endpoint (that is sent to EP0 but
specifying the target endpoint address in wIndex) are dispatched to the
current configuration's setup callback, requiring all gadget drivers to
dispatch the requests to the correct function driver.

To avoid this, record which endpoints are used by each function in the
composite driver SET CONFIGURATION handler and dispatch requests
targeted at endpoints to the correct function.
