2018-03-01ASoC: Intel: sst: Free streams on suspend, re-alloc on resumeHans de Goede
The Bay Trail SST-DSP firmware version looses track of all streams over a suspend/resume, failing any attempts to resume and/or free streams, with a SST_ERR_INVALID_STREAM_ID error. This commit adds support for free-ing the streams on suspend and re-allocating them on resume, fixing suspend/resume issues on devices using this firmware version. This new behavior gets triggered by a new flag in sst_platform_info which only gets set on Bay Trail platforms. This has been tested on the following devices: -Asus T100TA, Bay Trail + ALC5642 codec -Ployer MOMO7W, Bay Trail CR + ALC5652 codec Tested-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2018-03-01ASoC: Intel: sst: Add sst_realloc_stream() functionHans de Goede
Move the struct snd_sst_alloc_mrfld alloc parameters from the stack into struct stream_info and add a new sst_realloc_stream() function which can re-alloc a stream with the same parameters as before. This is a preparation patch for fixing suspend/resume issues with some SST / DSP firmware versions. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2018-03-01ASoC: Intel: sst: Remove unnecessary sst_init_stream() functionHans de Goede
sst_init_stream() has only one caller and all its function arguments are unused. Inline it on the one call site and remove it. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2018-03-01ASoC: Intel: sst: Fix error-code check in sst_pause_stream()Hans de Goede
The value returned by sst_prepare_and_post_msg() is a negated SST_ERR_* value, so we must check for -SST_ERR_INVALID_STREAM_ID. Note that sst_pause_resume() already has the correct check. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2018-01-08ASoC: Intel: sst: Fix some styleChristophe JAILLET
This patch fixes 3 small issues: - missing 2nd '*' at the beginning of a doxygen comment - extra space after a '\n' in a dev_dbg message - extra tab before a 'return" statement Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Mark Brown <broonie@kernel.org>
2018-01-08ASoC: Intel: sst: Fix the return value of 'sst_send_byte_stream_mrfld()'Christophe JAILLET
In some error handling paths, an error code is assiegned to 'ret'. However, the function always return 0. Fix it and return the error code if such an error paths is taken.

Don't use BUG_ON() for a non-critical sanity check on production systems. This patch either removes useless BUG_ON() calls. Signed-off-by: Takashi Iwai <tiwai@suse.de> Acked-By: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2016-11-29ASoC: Intel: atom: Make some messages to debug levelTakashi Iwai
Intel sst driver spews lots of kernel messages in INFO level; typically, it gives a kernel message at each time it allocates or frees a stream, or at each time when a stream is started or stopped. This will piles up quickly, and it's almost useless for normal users, so let's hide them to KERN_DEBUG level.

2015-11-21ASoC: Intel: pass correct parameter in sst_alloc_stream_mrfld()Dan Carpenter
"data" is always NULL in this function. I think we should be passing "&data" to sst_prepare_and_post_msg() instead of "data".
