2017-04-30ASoC: sti: Fix error handling if of_clk_get() failsDan Carpenter
We intended to return here. The current code has a static checker warning because we set "ret" but don't use it. Fixes: 76c2145ded6b ("ASoC: sti: Add CPU DAI driver for playback") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Acked-by: Arnaud POULIQUEN <arnaud.pouliquen@st.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2017-04-06ASoC: STI: Fix null ptr deference in IRQ handlerArnaud Pouliquen
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.

2016-09-14ASoC: sti: suppress inappropriate DT fieldsArnaud Pouliquen
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. Signed-off-by: Arnaud Pouliquen <arnaud.pouliquen@st.com> Signed-off-by: Mark Brown <broonie@kernel.org>

In case of error, the function syscon_regmap_lookup_by_phandle() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-04-18ASoC: sti: select player for I2S/TDM TX busMoise Gergaud

2016-04-12ASoC: sti: unip player tdm modeMoise Gergaud
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.

2015-11-25ASoC: sti: set iec958 channel status sampling freqMoise Gergaud
Previously, the iec958 channels status sampling freq was set only if not already set. It means that it is not updated for next PCM sessions. With this patch, we ensure the iec958 channels status sampling freq is set to the runtime rate for each PCM session.
