USB: serial: add generic wait_until_sent implementation

2013-06-13T17:49:48+00:00

commit dcf0105039660e951dfea348d317043d17988dfc upstream.

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.

TTY: switch tty_flip_buffer_push

2013-01-16T06:30:15+00:00

Now, we start converting tty buffer functions to actually use
tty_port. This will allow us to get rid of the need of tty in many
call sites. Only tty_port will needed and hence no more
tty_port_tty_get in those paths.

Now, the one where most of tty_port_tty_get gets removed:
tty_flip_buffer_push.

IOW we also closed all the races in drivers not using tty_port_tty_get
at all yet.

Also we move tty_flip_buffer_push declaration from include/linux/tty.h
to include/linux/tty_flip.h to all others while we are changing it
anyway.

TTY: switch tty_insert_flip_string

2013-01-16T06:22:35+00:00

Now, we start converting tty buffer functions to actually use
tty_port. This will allow us to get rid of the need of tty in many
call sites. Only tty_port will needed and hence no more
tty_port_tty_get in those paths.

tty_insert_flip_string this time.

TTY: switch tty_insert_flip_char

2013-01-16T06:21:36+00:00

Now, we start converting tty buffer functions to actually use
tty_port. This will allow us to get rid of the need of tty in many
call sites. Only tty_port will needed and hence no more
tty_port_tty_get in those paths.

tty_insert_flip_char is the next one to proceed. This one is used all
over the code, so the patch is huge.

USB: serial: export usb_serial_generic_chars_in_buffer

2012-10-30T20:19:30+00:00

Export generic chars_in_buffer implementation so it can be used in
subdrivers in combination with checks of any hardware buffers.

USB: Serial: usb-serial: remove debug module parameter

2012-09-18T15:05:17+00:00

Now that all usb-serial modules are only using dev_dbg()
the debug module parameter does not do anything at all, so
remove it to reduce any confusion if someone were to try
to use it.

USB: serial: remove debug parameter from usb_serial_debug_data()

2012-09-18T08:58:57+00:00

We should use dev_dbg() for usb_serial_debug_data() like all of the rest
of the usb-serial drivers use, so remove the debug parameter as it's not
needed.

USB: serial-generic: use a single set of device IDs

2012-06-13T21:01:56+00:00

The usb-serial-generic driver uses different device IDs for its USB
matching and its serial matching.  This can lead to problems: The
driver can end up getting bound to a USB interface without being
allowed to bind to the corresponding serial port.

This patch (as1557) fixes the problem by using the same device ID
table (the one that can be altered by the "vendor=" and "product="
module parameters) for both purposes.  The unused table is removed.
Now the driver will bind only to the intended devices.

USB: generic.c: remove dbg() usage

2012-05-15T23:27:18+00:00

dbg() is a usb-serial specific macro.  This patch converts
the generic.c driver to use dev_dbg() instead to tie into the
dynamic debug infrastructure.

USB: serial: rework usb_serial_register/deregister_drivers()

2012-05-08T22:46:14+00:00

This reworks the usb_serial_register_drivers() and
usb_serial_deregister_drivers() to not need a pointer to a struct
usb_driver anymore.  The usb_driver structure is now created dynamically
and registered and unregistered as needed.

This saves lines of code in each usb-serial driver.  All in-kernel users
of these functions were also fixed up at this time.  The pl2303 driver
was tested that everything worked properly.

Thanks for the idea to do this from Alan Stern.
