staging/speakup: Move out of staging

The nasty TODO items are done. Signed-off-by: Samuel Thibault Link: https://lore.kernel.org/r/20200729003531.907370-1-samuel.thibault@ens-lyon.org Signed-off-by: Greg Kroah-Hartman

staging: speakup: add SPDX identifier.

2018-01-15T15:03:44Z

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.

staging: speakup: flush tty buffers and ensure hardware flow control

2017-05-16T12:19:41Z

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.

staging: speakup: make input functionality swappable

2017-05-15T10:31:43Z

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.

staging: speakup: add send_xchar and tiocmset methods

2017-04-25T18:45:12Z

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.

staging: speakup: fix warning for static declaration
