* ASoC: sti: uniperif: fix 'defined by not used' warningPierre-Louis Bossart2020-07-101-1/+1
| | | | | | | | | | | | | | | | | Fix W=1 warning. The table uni_tdm_hw is declared in a header included by multiple C file. This isn't really a good practice but for now using __maybe_unused makes the following warning go away. sound/soc/sti/sti_uniperif.c:12: sound/soc/sti/uniperif.h:1351:38: warning: ‘uni_tdm_hw’ defined but not used [-Wunused-const-variable=] 1351 | static const struct snd_pcm_hardware uni_tdm_hw = { | ^~~~~~~~~~ Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Acked-by: Arnaud Pouliquen <arnaud.pouliquen@st.com> Link: https://lore.kernel.org/r/20200709162328.259586-2-pierre-louis.bossart@linux.intel.com Signed-off-by: Mark Brown <broonie@kernel.org>

* ASoC: STI: Fix null ptr deference in IRQ handlerArnaud Pouliquen2017-04-061-0/+1
| | | | | | | | | | | | | | | With RTlinux a race condition has been found that leads to NULL ptr crash: - On CPU 0: uni_player_irq_handler is called to treat XRUN "(player->state == UNIPERIF_STATE_STOPPED)" is FALSE so status is checked, dev_err(player->dev, "FIFO underflow error detected") is printed and then snd_pcm_stream_lock should be called to lock stream for stopping. - On CPU 1: application stop and close the stream. Issue is that the stop and shutdown functions are executed while "FIFO underflow error detected" is printed. So when CPU 0 calls snd_pcm_stream_lock, player->substream is already null.

* ASoC: sti: suppress inappropriate DT fieldsArnaud Pouliquen2016-09-141-16/+12
| | | | | | | | | | Update to suppress some DT nodes that can be handled in driver using compatible string. "dai-name", "st,version"and "st,mode" are suppressed "st,tdm-mode" is added to handle TDM mode.

* ASoC: sti: unip player tdm modeMoise Gergaud2016-04-121-0/+11
| | | | | | | | | | | | | | | | here are the changes to enable player tdm mode: - When TDM_ENABLE is set to 1, the i2s format should be automatically configured. Unfortunately this is not the case (HW bug). Then, we shall force DATA_SIZE setting. - Compute the transfer size for tdm mode: transfer size = user frame size - Manage tdm slots configuration given in DT. - Don't use mclk-fs when unip in tdm mode; use tdm slot config to compute frame size and to set mclk rate. - Refine the hw param (channels & format) according to tdm slot config.
