2020-09-03ASoC: fsl_sai: Support multiple data channel enable bitsShengjiu Wang
One data channel is one data line. From imx7ulp, the SAI IP is enhanced to support multiple data channels. If there is only two channels input and slots is 2, then enable one data channel is enough for data transfer. So enable the TCE/RCE and transmit/receive mask register according to the input channels and slots configuration. Move the data channel enablement from startup() to hw_params().

2020-08-18ASoC: fsl-asoc-card: Get "extal" clock rate by clk_get_rateShengjiu Wang
On some platform(.e.g. i.MX8QM MEK), the "extal" clock is different with the mclk of codec, then the clock rate is also different. So it is better to get clock rate of "extal" rate by clk_get_rate, don't reuse the clock rate of mclk.

2020-08-17ASoC: fsl_sai: Refine enable/disable TE/RE sequence in trigger()Shengjiu Wang
Current code enables TCSR.TE and RCSR.RE together, and disable TCSR.TE and RCSR.RE together in trigger(), which only supports one operation mode： 1. Rx synchronous with Tx: TE is last enabled and first disabled Other operation mode need to be considered also: 2. Tx synchronous with Rx: RE is last enabled and first disabled. 3. Asynchronous mode: Tx and Rx are independent. So the enable TCSR.TE and RCSR.RE sequence and the disable sequence need to be refined accordingly for #2 and #3. There is slightly against what RM recommennds with this change. For example in Rx synchronous with Tx mode, case "aplay 1.wav; arecord 2.wav" enable TE before RE. But it should be safe to do so, judging by years of testing results.

2020-08-03ASoC: fsl-asoc-card: Remove fsl_asoc_card_set_bias_level functionShengjiu Wang
With this case: aplay -Dhw:x 16khz.wav 24khz.wav There is sound distortion for 24khz.wav. The reason is that setting PLL of WM8962 with set_bias_level function, the bias level is not changed when 24khz.wav is played, then the PLL won't be reset, the clock is not correct, so distortion happens. The resolution of this issue is to remove fsl_asoc_card_set_bias_level. Move PLL configuration to hw_params and hw_free. After removing fsl_asoc_card_set_bias_level, also test WM8960 case, it can work.

In IEC958 spec, "The validity bit is logical "0" if the information in the main data field is reliable, and it is logical "1" if it is not". The default value of "ValCtrl" is zero, which means "Outgoing Validity always set", then all the data is not reliable, then some spdif sink device will drop the data. So set "ValCtrl" to 1, that is to clear "Outgoing Validity" in default.

2020-06-22ASoC: soc-component: merge snd_soc_component_read() and ↵Kuninori Morimoto
snd_soc_component_read32() We had read/write function for Codec, Platform, etc, but these has been merged into snd_soc_component_read/write(). Internally, it is using regmap or driver function. In read case, each styles are like below regmap ret = regmap_read(..., reg, &val); driver function val = xxx->read(..., reg); Because of this kind of different style, to keep same read style, when we merged each read function into snd_soc_component_read(), we created snd_soc_component_read32(), like below. commit 738b49efe6c6 ("ASoC: add snd_soc_component_read32") (1) val = snd_soc_component_read32(component, reg); (2) ret = snd_soc_component_read(component, reg, &val); Many drivers are using snd_soc_component_read32(), and some drivers are using snd_soc_component_read() today. In generally, we don't check read function successes, because, we will have many other issues at initial timing if read function didn't work. Now we can use soc_component_err() when error case. This means, it is easy to notice if error occurred. This patch aggressively merge snd_soc_component_read() and _read32(), and makes snd_soc_component_read/write() as generally style. This patch do 1) merge snd_soc_component_read() and snd_soc_component_read32() 2) it uses soc_component_err() when error case (easy to notice) 3) keeps read32 for now by #define 4) update snd_soc_component_read() for all drivers Because _read() user drivers are not too many, this patch changes all user drivers.

For mono channel, SSI will switch to Normal mode. In Normal mode and Network mode, the Word Length Control bits control the word length divider in clock generator, which is different with I2S Master mode (the word length is fixed to 32bit), it should be the value of params_width(hw_params). The condition "slots == 2" is not good for I2S Master mode, because for Network mode and Normal mode, the slots can also be 2. Then we need to use (ssi->i2s_net & SSI_SCR_I2S_MODE_MASK) to check if it is I2S Master mode. So we refine the formula for mono channel, otherwise there will be sound issue for S24_LE.

If we select the dma channel of ASRC, there is an issue for ideal ratio case, the speed of copy data is faster than sample frequency, because ASRC output data is very fast in ideal ratio mode. So it is reasonable to use the dma channel of Back-End peripheral. then copying speed of DMA is controlled by data consumption speed in the peripheral FIFO, Signed-off-by: Shengjiu Wang <shengjiu.wang@nxp.com> Reviewed-by: Nicolin Chen <nicoleotsuka@gmail.com> Link: https://lore.kernel.org/r/424ed6c249bafcbe30791c9de0352821c5ea67e2.1591947428.git.shengjiu.wang@nxp.com Signed-off-by: Mark Brown <broonie@kernel.org>
