Greg Kroah-Hartman a407235bf2 staging: speakup: remove redundant license text
Now that the SPDX tag is in all drivers/staging/speakup/ files, that
identifies the license in a specific and legally-defined manner.  So the
extra GPL text wording can be removed as it is no longer needed at all.

This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text.  And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.

No copyright headers or other non-license-description text was removed.

Greg Kroah-Hartman 6496922817 staging: speakup: add SPDX identifier.
It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Fix up the remaining staging speakup files to have a proper SPDX
identifier, based on the license text in the file itself.  The SPDX
identifier is a legally binding shorthand, which can be used instead of
the full boiler plate text.

This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

Okash Khawaja 8a21ff775f staging: speakup: make ttyio synths use device name
This patch introduces new module parameter, dev, which takes a string
representing the device that the external synth is connected to, e.g.
ttyS0, ttyUSB0 etc. This is then used to communicate with the synth.
That way, speakup can support more than ttyS*. As of this patch, it
only supports ttyS*, ttyUSB* and selected synths for lp*. dev parameter
is only available for tty-migrated synths.

Users will either use dev or ser as both serve same purpose. This patch
maintains backward compatility by allowing ser to be specified. When
both are specified, whichever is non-default, i.e. not ttyS0, is used.
If both are non-default then dev is used.

Okash Khawaja 1c5973675c staging: speakup: flush tty buffers and ensure hardware flow control
This patch fixes the issue where TTY-migrated synths would take a while
to shut up after hitting numpad enter key. When calling synth_flush,
even though XOFF character is sent as high priority, data buffered in
TTY layer is still sent to the synth. This patch flushes that buffered
data when synth_flush is called.

It also tries to ensure that hardware flow control is enabled, by
setting CRTSCTS using tty's termios.

Okash Khawaja ca693dcd5c staging: speakup: make input functionality swappable
This moves functions which take input from external synth, into struct
spk_io_ops. The calling code then uses serial implementation of those methods
through spk_io_ops. That way we can add a parallel TTY-based implementation and
simply replace serial with TTY. That is what the next patch in this series does.

speakup_decext.c has get_last_char function which reads the most recent
available character from the synth. This patch changes that by defining
read_buff_add callback method of spk_syth and letting that update the last_char
global character read from the synth. read_buff_add is called from ISR, so
there is a possibility for last_char to be stale. Therefore it is marked as
volatile. It also pulls a repeated get_index implementation into synth.c, to
be used as a utility function.

Okash Khawaja 98c1fda752 staging: speakup: move those functions which do outgoing serial comms, into serialio.c
This moves spk_synth_immediate and spk_serial_synth_probe functions into
serialio.c. These functions do outgoing serial comms. The move is a step
towards collecting all serial comms in serialio.c. This also renames
spk_synth_immediate to spk_serial_synth_immediate.

Code inside those functions has not been changed. Along the way, this patch
also fixes a couple of spots which were calling spk_synth_immediate directly,
so that the calls now happen via the spk_syth struct.

Okash Khawaja 1e441594e5 staging: speakup: add spk_io_ops struct to spk_synth
This patch adds spk_io_ops struct which contain those methods whose job is to
communicate with synth device. Currently, all comms with external synth
device use raw serial i/o. The idea is to group all methods which do the
actual communication with external device into this new struct. Then migrating
a serial-based synth over to an alternative to raw serial i/o will mean
swapping serial spk_io_ops instance with the io_ops instance of the new
method, making the migration simpler.

At the moment, this struct only contains one method, synth_out but more will
be added in future when migrating synths which require input functionality.
Also at the moment, synth_out method has one implementation which uses
serial i/o. Plan is to add an alternative.

Okash Khawaja 9176d156ca staging: speakup: spk_serial_out and spk_wait_for_xmitr to take synth arg
These two functions are always called from a context where spk_synth instance
is available. They also use the spk_synth instance but instead of taking it
as an argument, they rely on a global spk_synth instance inside synth.c which
points to the same synth as the one being passed in as argument.

Samuel Thibault 89fc2ae80b speakup: extend synth buffer to 16bit unicode characters
This extends the synth buffer slots to 16bit, so as to hold 16bit
unicode characters.

synth_buffer_getc and synth_buffer_peek now return 16bit characters.
Speech synthesizers which do not support characters beyond latin1 can
use the synth_buffer_skip_nonlatin1() helper to skip the non-latin1
characters before getting or peeking. All synthesizers are made to use
it for now.

This makes synth_buffer_add take a 16bit character. For simplicity for
now, synth_printf is left to using latin1 formats and strings.
synth_putwc, synth_putwc_s, synth_putws and synth_putws_s helpers are
however added to put 16bit characters and strings.

It uses the unnecessary S_IFREG bit which broke when my
stricter-checking-for-mode patch went in.

Since we're fixing it anyway, the extra level of indirection is
confusing for readers (ROOT_W == rw-r--r-- for example).

Also, many of these are other-writable.  Is that really intended?
