ASoC: fsl_sai: Enable BCI bit if SAI works on synchronous mode with BYP asserted There's an issue on SAI synchronous mode that TX/RX side can't get BCLK from RX/TX it sync with if BYP bit is asserted. It's a workaround to fix it that enable SION of IOMUX pad control and assert BCI. For example if TX sync with RX which means both TX and RX are using clk form RX and BYP=1. TX can get BCLK only if the following two conditions are valid: 1. SION of RX BCLK IOMUX pad is set to 1 2. BCI of TX is set to 1 Signed-off-by: Chancel Liu <chancel.liu@nxp.com> Acked-by: Shengjiu Wang <shengjiu.wang@gmail.com> Link: https://lore.kernel.org/r/20230530103012.3448838-1-chancel.liu@nxp.com Signed-off-by: Mark Brown <broonie@kernel.org>

ASoC: fsl_sai: MCLK bind with TX/RX enable bit On i.MX8MP, the sai MCLK is bound with TX/RX enable bit, which means the TX/RE enable bit need to be enabled then MCLK can be output on PAD. Some codec (for example: WM8962) needs the MCLK output earlier, otherwise there will be issue for codec configuration. Add new soc data "mclk_with_tere" for this platform and enable the MCLK output in startup stage. As "mclk_with_tere" only applied to i.MX8MP, currently The soc data is shared with i.MX8MN, so need to add an i.MX8MN own soc data with "mclk_with_tere" disabled.

ASoC: fsl_sai: add tdm slots operation support Add tdm slots operation support. If tdm slots and slot width have been configured in machine driver, we should use these values. Otherwise, using relevant channels and word length to set slots and slot width. SAI will generate BCLK depends on sample rate, slots and slot width. And there may be unused BCLK cycles before each LRCLK transition.

ASoC: fsl_sai: add sai master mode support When sai works on master mode, set its bit clock and frame clock. SAI has 4 MCLK source, bus clock, MCLK1, MCLK2 and MCLK3. fsl_sai_set_bclk will select proper MCLK source, then calculate and set the bit clock divider. After fsl_sai_set_bclk, enable the selected mclk in hw_params(), and add hw_free() to disable the mclk.

ASoC: fsl-sai: using 'lsb-first' property instead of 'big-endian-data'. The 'big-endian-data' property is originally used to indicate whether the LSB firstly or MSB firstly will be transmitted to the CODEC or received from the CODEC, and there has nothing relation to the memory data. Generally, if the audio data in big endian format, which will be using the bytes reversion, Here this can only be used to bits reversion. So using the 'lsb-first' instead of 'big-endian-data' can make the code to be readable easier and more easy to understand what this property is used to do. This property used for configuring whether the LSB or the MSB is transmitted first for the fifo data.

ASoC: fsl_sai: Add asynchronous mode support SAI supports these operation modes: 1) asynchronous mode Both Tx and Rx are set to be asynchronous. 2) synchronous mode (Rx sync with Tx) Tx is set to be asynchronous, Rx is set to be synchronous. 3) synchronous mode (Tx sync with Rx) Rx is set to be asynchronous, Tx is set to be synchronous. 4) synchronous mode (Tx/Rx sync with another SAI's Tx) 5) synchronous mode (Tx/Rx sync with another SAI's Rx) * 4) and 5) are beyond this patch because they are related with another SAI. As the initial version of this SAI driver, it supported 2) as default while the others were totally missing. So this patch just adds supports for 1) and 3).

ASoC: fsl_sai: Add clock controls for SAI The SAI mainly has the following clocks: bus clock control and configure registers and to generate synchronous interrupts and DMA requests. mclk1, mclk2, mclk3 to generate the bit clock when the receiver or transmitter is configured for an internally generated bit clock. So this patch adds these clocks and their clock controls to the driver. [ To concern the old DTB cases, I've added a bit of extra code to make the driver compatible with them. And by marking clock NULL if failed to get, the clk_prepare() or clk_get_rate() would easily return 0 so no further path should be broken. -- by Nicolin ] Signed-off-by: Nicolin Chen <Guangyu.Chen@freescale.com> Acked-by: Xiubo Li <Li.Xiubo@freescale.com> Signed-off-by: Mark Brown <broonie@linaro.org>

ASoC: fsl_sai: Separately enable interrupts for Tx and Rx streams We only enable one side interrupt for each stream since over/underrun on the opposite stream would be resulted from what we previously did, enabling TERE but remaining FRDE disabled, even though the xrun on the opposite direction will not break the current stream.

ASoC: fsl_sai: Fix buggy configurations in trigger() The current trigger() has two crucial problems: 1) The DMA request enabling operations (FSL_SAI_CSR_FRDE) for Tx and Rx are now totally exclusive: It would fail to run simultaneous Tx-Rx cases. 2) The TERE disabling operation depends on an incorrect condition -- active reference count that only gets increased in snd_pcm_open() and decreased in snd_pcm_close(): The TERE would never get cleared. So this patch overwrites the trigger function by following these rules: A) We continue to support tx-async-while-rx-sync-to-tx case alone, which's originally limited by this fsl_sai driver, but we make the code easy to modify for the further support of the opposite case. B) We enable both TE and RE for PLAYBACK stream or CAPTURE stream but only enabling the DMA request bit (FSL_SAI_CSR_FRDE) of the current direction due to the requirement of SAI -- For tx-async-while-rx-sync-to-tx case, the receiver is enabled only when both the transmitter and receiver are enabled. Tested cases: a) aplay test.wav -d5 b) arecord -r44100 -c2 -fS16_LE test.wav -d5 c) arecord -r44100 -c2 -fS16_LE -d5 | aplay d) (aplay test2.wav &); sleep 1; arecord -r44100 -c2 -fS16_LE test.wav -d1 e) (arecord -r44100 -c2 -fS16_LE test.wav -d5 &); sleep 1; aplay test.wav -d1 Signed-off-by: Nicolin Chen <Guangyu.Chen@freescale.com> Acked-by: Xiubo Li <Li.Xiubo@freescale.com> Signed-off-by: Mark Brown <broonie@linaro.org>

ASoC: fsl_sai: Add isr to deal with error flag It's quite cricial to clear error flags because SAI might hang if getting FIFO underrun during playback (I haven't confirmed the same issue on Rx overflow though). So this patch enables those irq and adds isr() to clear the flags so as to keep playback entirely safe.
