USB: serial: add generic wait_until_sent implementation

2013-05-17T00:32:21Z

Add generic wait_until_sent implementation which polls for empty hardware buffers using the new port-operation tx_empty. The generic implementation will be used for all sub-drivers that implement tx_empty but does not define wait_until_sent. Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: serial: add wait_until_sent operation

2013-05-17T00:32:21Z

Add wait_until_sent operation which can be used to wait for hardware buffers to drain. Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: serial: remove unused MSR-wait queue

2013-03-25T20:54:30Z

Remove the port MSR-wait queue now that all drivers have been migrated to the tty-port queue. Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: serial: add generic get_icount implementation

2013-03-25T20:50:51Z

Add generic get_icount implementation that subdrivers relying on the port interrupt counters can use. Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: serial: add generic TIOCMIWAIT implementation

2013-03-25T20:50:51Z

Add generic TIOCMIWAIT implementation which correctly handles hangup, USB-device disconnect, does not rely on the deprecated sleep_on functions and hence does not suffer from the races currently affecting several usb-serial drivers. This makes it much easier to add TIOCMIWAIT support to subdrivers as the tricky details related to hangup and disconnect (e.g. atomicity, that the private port data may have been freed when woken up, and waking up processes at disconnect) have been handled once and for all. To add support to a subdriver, simply set the tiocmiwait-port-operation field, update the port icount fields and wake up any process sleeping on the tty-port modem-status-change wait queue on changes. Note that the tty-port initialised flag can be used to detect disconnected as the port will be hung up as part of disconnect (and cannot be reactivated due to the disconnected flag). However, as the tty-port implementation currently wakes up processes before calling port shutdown, the tty-hupping flag must also be checked to detect hangup for now.

USB: serial: add tiocmiwait subdriver operation

2013-03-25T20:50:50Z

Add tiocmiwait operation to struct usb_serial_driver. Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: serial: remove generic release callback

2013-03-25T20:48:26Z

Remove empty generic release implementation and make the release callback non-mandatory (like attach, probe and disconnect). Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: serial: remove generic disconnect callback

2013-03-25T20:48:26Z

Remove the now empty generic disconnect callback and make the disconnect callback non-mandatory. Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: serial: add modem-status-change wait queue

2013-03-21T22:59:02Z

Add modem-status-change wait queue to struct usb_serial_port that subdrivers can use to implement TIOCMIWAIT. Currently subdrivers use a private wait queue which may have been released when waking up after device disconnected. Note that we're adding a new wait queue rather than reusing the tty-port one as we do not want to get woken up at hangup (yet).

USB: ezusb: add support for Cypress FX2LP

2012-09-18T16:23:47Z

This Patch adds support for the newer Cypress FX2LP. It also adapts three drivers currently using ezusb to the interface change. (whiteheat and keyspan[_pda]) Signed-off-by: René Bürgel Signed-off-by: Greg Kroah-Hartman
