2018-01-15staging: speakup: remove redundant license textGreg Kroah-Hartman1-10/+0
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.

2018-01-15staging: speakup: add SPDX identifier.Greg Kroah-Hartman1-0/+1
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.

2017-06-27staging: speakup: make ttyio synths use device nameOkash Khawaja1-0/+3
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.

2017-05-16staging: speakup: flush tty buffers and ensure hardware flow controlOkash Khawaja1-0/+1
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.

2017-05-15staging: speakup: make input functionality swappableOkash Khawaja1-2/+2
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.

2017-04-25staging: speakup: add send_xchar and tiocmset methodsOkash Khawaja1-8/+1
This adds two methods to spk_synth struct: send_xchar and tiocmset, and creates serial implementation for each of them. It takes existing code in apollo, audptr and spkout which already fits the behaviour of send_xchar and tiocmset. In follow-up patches there will be TTY-based implementations of these methods. Then migrating the synths to TTY will include repointing these methods to their TTY implementations Rest of the changes simply make use of serial implementation of these two functions.

2017-03-17staging: speakup: move those functions which do outgoing serial comms, into serialio.cOkash Khawaja1-2/+2
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.

2017-03-16staging: speakup: add spk_io_ops struct to spk_synthOkash Khawaja1-1/+2
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.

2017-03-16staging: speakup: spk_serial_out and spk_wait_for_xmitr to take synth argOkash Khawaja1-1/+1
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.

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?
